Sonic Speed Simulator Pets and Trails Guide: Leveling, Upgrades and Best Choices

What Are Friends in Sonic Speed Simulator?

Friends are Sonic Speed Simulator's pet system.

They include Chao, Wisps, Koco, Omochao, and many other collectible companions.

When equipped, Friends follow your character and add bonuses to your account. Core Friend stats commonly include:

• XP;

• Rings;

• Damage.

Some Friends can also provide secondary stats such as:

• Luck;

• Magnet;

• Stamina;

• Event bonuses;

• other specialized effects.

Friends are obtained through several systems, including Friend Machines, quests, events, rewards, shops, and other content.

How Many Friends Can You Equip?

Players normally have three Friend slots.

An optional +2 Pet Slots gamepass can increase this to five equipped Friends.

That makes equipment selection important.

If you only have three slots, filling them with random Friends because they look good can significantly reduce your progression efficiency.

Instead, choose Friends that support what you are currently doing.

What Are Trails?

Trails are another type of equippable item.

They create a visual effect behind your character while also providing useful stat bonuses.

Unlike Friends, you can normally equip only one Trail at a time.

That makes your Trail particularly important.

A strong Trail can provide substantial bonuses to:

• XP;

• Rings;

• Damage.

Some Trails may also offer additional specialized stats depending on the item.

Friends vs Trails: Which Matters More?

Both matter, but Friends generally deserve greater attention in modern Sonic Speed Simulator.

Historically, Trails could be extremely important because Fast Friend calculations interacted differently with equipment.

That changed.

Current community documentation notes that Fast Friends no longer use Trail stats when calculating their main XP, Ring, and Damage values. As a result, your regular Friends are now the more important foundation for Fast Friend builds.

That does not make Trails weak.

A powerful Trail still adds a large independent bonus to your build.

Think of the system like this:

Friends establish much of your core equipment power, while your Trail provides one additional specialized boost.

Understanding Friend and Trail Stats

Before choosing equipment, understand what each stat actually helps you do.

XP

XP bonuses increase the value of XP collected from Chaos Orbs.

The XP you receive from Chaos Orbs is affected by Friends, Trails, your base multipliers, and active XP boosts.

XP is especially valuable when:

• leveling;

• pushing Rebirths;

• completing level-based Main Quests;

• progressing through newly unlocked worlds.

For most progression-focused players, XP is one of the most useful equipment stats.

Rings

Ring bonuses increase how many Rings you receive from Ring pickups.

Rings are used by several systems, including equipment upgrades and machines.

Ring-focused Friends and Trails are useful when you specifically need currency rather than levels.

Damage

Damage affects how much damage you deal to enemies.

A damage setup becomes more useful for:

• enemy objectives;

• combat events;

• boss-related content when available;

• quests involving Badniks or other targets.

Damage is much less important while simply grinding Chaos Orbs.

Magnet

Magnet effects improve how easily nearby collectibles are pulled toward you.

This can make farming more comfortable because your route does not need to pass directly through every collectible.

Magnet can be particularly useful for:

• event items;

• Rings;

• Chaos Orbs;

• densely packed collectibles.

Luck

Luck is connected to systems where additional luck can improve outcomes or collection efficiency.

It is more specialized than XP or Rings and becomes increasingly useful once you understand exactly what content you are farming.

Stamina

Stamina supports gameplay systems that use stamina.

It is usually a secondary consideration compared with XP for standard leveling, but it can be valuable in specialized movement or character setups.

Event Stats

Certain Friends can provide Event bonuses.

These are useful when an active or permanent event calculates progress using Event stats.

However, an Event-focused Friend is not automatically your best Friend for general leveling.

Always match equipment to the activity.

How Friend and Trail Leveling Works in 2026

This is one of the most important recent changes.

Since the March 14, 2026 Systems Revamp, equipped pets and Trails can level up while you collect Chaos Orbs. Upgrade Machines remain available if you want to increase levels manually.

That means you now have two main approaches.

Natural Leveling

Equip the Friend or Trail you want to improve and collect Chaos Orbs.

As you continue running and farming XP, the equipped item gains its own progression.

This is usually the most resource-efficient approach because you are simultaneously:

• leveling your player;

• progressing toward Rebirths;

• leveling Friends;

• leveling your Trail.

You are accomplishing several objectives through the same activity.

Upgrade Machine

Upgrade Machines can still increase Friend and Trail levels directly.

The traditional Upgrader supports Friend progression up to level 25, with costs involving Rings and Red Star Rings depending on the item and upgrade stage.

This is useful when:

• you need an item upgraded immediately;

• you have abundant currency;

• you do not want to naturally level it;

• a quest specifically interacts with upgrading.

However, because natural leveling now exists, spending currency is no longer automatically the smartest choice.

What Is the Maximum Friend Level?

Regular Friends currently have a maximum level of 25.

The same level cap applies to Trails.

As equipment levels increase, their bonuses improve.

A level 25 Friend should therefore be evaluated differently from the same Friend at level 1.

When comparing equipment, always compare items at equivalent levels when possible.

Should You Use the Upgrade Machine?

Sometimes.

Before the 2026 revamp, Upgrade Machines were far more important for ordinary equipment progression.

Now, a useful rule is:

Naturally level equipment when you are already farming. Use the Upgrade Machine when speed matters more than currency efficiency.

Natural Leveling Is Better When

You are actively:

• pushing Rebirths;

• farming XP;

• exploring worlds;

• completing Chaos Orb objectives.

Simply equip the item and let normal gameplay improve it.

Upgrade Machines Are Better When

You:

• need a maxed Friend immediately;

• are preparing equipment before a specific activity;

• have more Rings than you need;

• want to finish an upgrade-related objective.

Do not spend Red Star Rings automatically just because an upgrade button exists.

What Is Fusion?

Fusion lets you combine identical max-level Friends or Trails into a stronger evolved version.

For regular Friends, the Fusion Machine requires five fully leveled identical Friends.

For Trails, it accepts three to five fully leveled identical Trails, depending on the fusion setup.

Fusion costs Red Star Rings.

The cost depends partly on where the item originates.

How Much Stronger Is Fused Equipment?

Fusion provides a major stat increase.

Current Fusion Machine documentation states:

• a fused Friend receives 2.5× stats;

• a fused Trail receives 5× stats.

That is significant.

It means a strong fused Friend can be dramatically more useful than collecting many unrelated Friends that remain unupgraded.

Should You Fuse Every Friend?

No.

Fusion is valuable, but you should consider the cost.

You need:

• multiple identical copies;

• fully leveled items;

• Red Star Rings.

Before committing, ask whether the Friend will remain useful once fused.

Good Fusion Candidate

A Friend that has:

• excellent XP;

• excellent Rings;

• excellent Damage;

• a strong secondary stat;

• long-term usefulness;

• value as a Fast Friend stat source.

Poor Fusion Candidate

A weak early-game Friend that you will replace shortly afterward.

Fusion should improve equipment you actually intend to use.

Should You Fuse Trails?

The same principle applies.

Fused Trails gain a large stat increase, but copies and Red Star Rings still have value.

A strong Trail that supports your primary activity is a much better fusion target than an early Trail you obtained simply because three copies happened to be available.

What Are Fast Friends?

Fast Friends are a separate, advanced type of Friend.

They do not work exactly like ordinary Chao.

Fast Friends use a Star Rank system and can reach 6 Stars. They are upgraded through their own evolution mechanics using Red Star Rings and other Friends as upgrade material or success-chance contributors.

Fast Friends become particularly valuable because their main stats scale from your best regular Friend stats.

How Fast Friend Stats Work

This is one of the most important equipment mechanics to understand.

Fast Friends derive their core:

• XP;

• Rings;

• Damage

from the best corresponding stats among your regular Friends.

Current Fast Friend documentation gives these scaling values:

• 1 Star: 90% of the reference stat;

• 2 Stars: 100%;

• 3 Stars: 110%;

• 4 Stars: 120%;

• 5 Stars: 130%;

• 6 Stars: 150%.

This creates a powerful interaction.

Suppose your inventory contains:

• one extremely strong XP Friend;

• one extremely strong Ring Friend;

• one extremely strong Damage Friend.

Your Fast Friends can use those best values as their statistical foundation.

You therefore do not necessarily need five copies of the strongest regular Chao.

You need strong benchmark Friends for the individual stats you care about.

Community discussions from April 2026 also consistently report that Fast Friends reference the highest appropriate regular Friend stat in your inventory rather than requiring multiple copies of that Friend.

Do Your Best Regular Friends Need to Be Equipped?

Current player testing indicates that Fast Friend scaling uses strong regular Friends from your inventory, rather than requiring each reference Friend to be actively equipped.

That means you should be extremely careful when cleaning your inventory.

Deleting an apparently unused Chao with an exceptional XP, Ring, or Damage stat could weaken your Fast Friend setup.

Fast Friend Secondary Stats

Fast Friends also have specialized secondary bonuses.

Current documentation associates different Fast Friend families with stats such as Luck, Stamina, and Magnet.

This means two Fast Friends with similar core scaling can still serve different purposes.

For example, one may be better when you want:

• Luck;

while another may support:

• Magnet;

• Stamina;

• Event progression.

Do not judge Fast Friends only by appearance.

Regular Friends Are Still Important

Once players unlock Fast Friends, it is tempting to believe normal Chao become useless.

That is incorrect.

Your strongest normal Friends are still extremely important because they provide the benchmark stats Fast Friends use.

A good endgame inventory therefore contains strong regular Friends even if many of your active slots are eventually occupied by Fast Friends.

Best Friends for XP

According to the current community-maintained equipment rankings available during this guide's research, the Metal Sonic 3.0 Omochao is listed as the strongest Friend for raw XP.

Its listed fused level 25 stats include approximately:

• +2,575,000 XP

• +14,250 Rings

• +20 Luck

• +4 Magnet.

Other highly ranked XP choices currently include:

• Jet Chao;

• Rockstar Silver Chao;

• Holographic Omochao;

• Koco Mask Chao.

Best Choice for Leveling

If your goal is:

level → Rebirth → level again

then raw XP should generally be your priority.

A strong XP Friend provides value every time you collect Chaos Orbs.

Best Friends for Rings

The current equipment ranking lists Sunstone Chao as the strongest Ring-focused regular Friend, at approximately +355,000 Rings when fused and maxed.

Other highly ranked Ring options include:

• Orange Shadow Omochao;

• Blue Shadow Omochao;

• Astral Chao;

• Rouge Chao;

• Metal Sonic Omochao.

When to Use Ring Friends

Use them when:

• farming regular Rings;

• preparing for equipment costs;

• trying to build a strong Ring benchmark for Fast Friends.

Do not keep a Ring build equipped while pushing Rebirth levels unless you actually need the currency.

Best Friends for Damage

The current ranking lists the You Friend as the strongest raw Damage Friend, with a listed fused level 25 Damage value far ahead of normal alternatives.

Conveniently, the 1billion code was still being reported as active in early September 2026 and awards the You pet, although code availability can change.

Other strong documented Damage choices include:

• Kronos Island Koco 1;

• Kronos Island Koco 2;

• Thundercloud Chao;

• Samurai Chao.

Why Keep a Damage Friend?

Even if you rarely equip it directly, a powerful Damage Friend can remain valuable as the Damage reference for your Fast Friends.

That makes strong specialist Friends worth keeping.

Best Trail for XP

The current community ranking places Emerald Energy Trail at the top for raw XP.

Its listed fused level 25 stats include:

• +500,000 XP

• +3,500 Rings

• +287 Damage.

Other strong XP options include:

• Cyloop Trail;

• Trick O' Treat Trail;

• Ice Breaker Trail;

• Phantom Copy Trail;

• Luminosity Green Trail.

For pure Rebirth leveling, choose the highest XP Trail you currently own.

Best Trail for Rings

The current ranking identifies Ice Breaker Trail as the strongest Ring Trail, with approximately:

• +202,500 XP;

• +202,500 Rings;

• +21,600 Damage

at fused level 25.

That makes it particularly useful because it is not purely a Ring item.

It provides strong balanced stats across several categories.

Other documented Ring-oriented choices include:

• Golden Style Trail;

• Phantom Copy Trail;

• Dark Star Trail;

• Resistance Trail.

Best Trail for Damage

Ice Breaker Trail also currently leads the community ranking for Trail Damage, with its listed +21,600 Damage value.

Other Damage alternatives include:

• Golden Style Trail;

• Luminosity Green Trail;

• Eggstreme Trail;

• Dark Star Trail;

• Rose Petal Trail;

• Frontier Blur Trail.

Best Permanently Available Choices

There is an important difference between:

best item in the game

and:

best item you can reasonably obtain.

Many top Friends and Trails come from previous events, limited content, trading, or rotating systems.

Current community documentation identifies several strong, consistently available options:

• Astral Chao

• Sunstone Chao

• Kronos Island Koco 1

• Kronos Island Koco 2

• Ice Breaker Trail

These are useful targets because you do not have to build your entire progression plan around a discontinued event item.

Best Equipment Depends on Your Goal

There is no single loadout that is best for everything.

Build around the objective.

Best Setup for Leveling and Rebirths

Prioritize:

1. highest available XP Friends;

2. Fast Friends benefiting from a strong XP benchmark;

3. highest available XP Trail.

XP matters more than Ring or Damage bonuses when your objective is reaching the next level cap.

Best Setup for Ring Farming

Prioritize:

1. highest Ring Friend;

2. Fast Friends scaling from that Friend;

3. highest Ring Trail.

Do not sacrifice Ring stats for Damage unless your farming method actually requires fighting enemies.

Best Setup for Combat

Prioritize:

1. strongest Damage Friend;

2. Fast Friends scaling from strong Damage;

3. strongest Damage Trail.

Secondary stats become less important unless the activity specifically rewards them.

Best Setup for Events

Check what the event actually requires.

If the objective involves:

• collecting items → Magnet may help;

• earning Event progress → Event stats may matter;

• defeating enemies → Damage becomes more valuable;

• collecting Chaos Orbs → XP equipment can help progression simultaneously.

Do not assume your normal XP build is automatically best for every event.

Balanced vs Specialized Equipment

A common mistake is always choosing the Friend with the largest total number of stats.

That is not necessarily optimal.

Consider two hypothetical Friends:

Friend A

• huge XP;

• almost no Rings.

Friend B

• moderate XP;

• moderate Rings;

• moderate Damage.

Friend B may look more balanced.

But if you are grinding Rebirths, Friend A can still be much better.

Use Specialized Builds

The most efficient players switch their equipment based on the activity rather than trying to create one mediocre setup for everything.

Keep:

• XP equipment;

• Ring equipment;

• Damage equipment;

• useful secondary-stat items.

Then swap when your goal changes.

Rarity Does Not Automatically Mean Best

Higher rarity often correlates with stronger items, but rarity alone should never determine your equipment choice.

Compare actual stats.

An older Exotic may be weaker than a newer item with better scaling.

Likewise, a Friend with great XP may be terrible for Ring farming.

Use the numbers, not the rarity label.

Why Level 25 Stats Matter

Comparing a level 1 Friend against a fully upgraded Friend can produce misleading conclusions.

Current best-equipment rankings generally compare items at Fused Level 25.

That creates an equal baseline.

When deciding whether to invest resources, look at:

• current stats;

• level 25 potential;

• fused potential;

• secondary stats;

• availability;

• upgrade cost.

Do Not Delete Strong Specialist Friends

Inventory management becomes increasingly important as your collection grows.

The game includes locking and multi-select tools to make Friend inventory management easier.

Before deleting duplicates or old-looking equipment, check its stats.

A Friend may not belong in your active loadout but still be:

• your highest XP Friend;

• your strongest Ring Friend;

• your strongest Damage Friend;

• useful for Fast Friend scaling;

• rare or difficult to replace;

• useful for future Fusion.

Lock important items before mass-deleting inventory.

When Should You Upgrade a New Friend?

Do not immediately max every new Friend.

Compare it against what you already own.

Upgrade It When

The Friend:

• beats one of your current main stats;

• gives a secondary stat you need;

• will become significantly stronger when fused;

• improves your Fast Friend benchmark;

• is useful for a current activity.

Skip or Delay It When

The Friend:

• is immediately weaker than your existing equipment;

• has no useful secondary stat;

• will require expensive Fusion you cannot complete;

• is only being upgraded because it is new.

Saving resources gives you more flexibility when a genuinely strong item appears.

When Should You Upgrade a Trail?

Because only one Trail can be equipped, the decision is easier.

Ask:

Does this Trail improve the stat I currently need?

If your existing XP Trail is already dramatically stronger, there is little reason to spend Red Star Rings maxing another XP Trail purely for progression.

Collection goals are separate from performance goals.

Common Friend and Trail Mistakes

Spending Red Star Rings on Weak Gear

Red Star Rings are used across several important systems.

Natural leveling now makes some manual upgrades unnecessary.

Do not spend RSR simply to save a few minutes on weak equipment.

Ignoring Natural Leveling

Since March 2026, equipped pets and Trails can level through Chaos Orb collection.

Older guides may fail to mention this.

Fusing Weak Friends

Five maxed Friends plus a Fusion cost is a significant investment.

Make sure the resulting Friend deserves it.

Deleting Your Best Stat Friend

This becomes particularly damaging once you use Fast Friends.

Your strongest regular Friends can determine Fast Friend core stats.

Comparing Different Levels

A level 25 Friend will naturally look much stronger than a fresh level 1 item.

Compare equivalent progression whenever possible.

Equipping Only Balanced Gear

Balanced stats are convenient.

Specialized stats are often more efficient.

Build for what you are doing.

Assuming the Old Best Item Is Still Best

Sonic Speed Simulator receives frequent content updates, and the community's own equipment-ranking page explicitly warns that the best Friends and Trails can change with new updates.

Always check actual current stats before making a large investment.

Practical Equipment Progression

You do not need perfect equipment immediately.

Early Progression

Use whichever Friends provide your strongest XP bonuses.

Equip your best XP Trail.

Naturally level them while completing Main Quests and Rebirths.

Developing Account

Start separating your inventory into:

• XP;

• Rings;

• Damage.

Keep stronger specialist Friends even if they are not currently equipped.

Begin fusing equipment that has clear long-term value.

Advanced Account

Build powerful regular Friends for each major stat.

Then develop Fast Friends around those benchmark stats and select Fast Friend secondary bonuses that fit your preferred activities.

At this stage, optimized specialist builds become much more valuable than random high-rarity equipment.

Sonic Speed Simulator Pets and Trails FAQ

Are pets called Friends in Sonic Speed Simulator?

Yes. The game's equipment system refers to pets as Friends, although players frequently call them pets or Chao.

How do Friends level up?

Since the March 14, 2026 Systems Revamp, equipped Friends can gain levels while you collect Chaos Orbs. Upgrade Machines can still level them manually.

How do Trails level up?

Trails can also gain levels naturally while equipped and collecting Chaos Orbs, or you can use an Upgrade Machine.

What is the maximum Friend level?

Regular Friends currently reach level 25.

What is the maximum Trail level?

Trails also currently reach level 25.

How many Friends can you equip?

Players normally equip three Friends. The optional +2 Pet Slots gamepass increases this to five.

How many Trails can you equip?

One Trail can normally be equipped at a time.

How do you fuse Friends?

You need five identical fully leveled regular Friends and access to a Fusion Machine. Fusion also costs Red Star Rings.

How do you fuse Trails?

Fusion Machines allow identical max-level Trails to be combined into a stronger fused version. Current documentation allows three to five fully leveled Trails depending on the fusion.

What does Fusion do?

Current documentation lists a 2.5× stat increase for fused Friends and a 5× stat increase for fused Trails.

What is the best Friend for XP?

The current community-maintained equipment ranking lists Metal Sonic 3.0 Omochao as the strongest raw XP Friend.

The current ranking lists the You Friend as the strongest raw Damage option.

What is the best XP Trail?

The current community ranking places Emerald Energy Trail first for XP.

What is the best Ring Trail?

Ice Breaker Trail currently leads the Ring Trail ranking.

What are Fast Friends?

Fast Friends are specialized Friends with their own Star Rank system. Their main XP, Ring, and Damage stats scale from your strongest regular Friend stats.

Are Trails used to determine Fast Friend stats?

No. Current documentation states that Fast Friends no longer factor Trail stats into their core scaling. Strong regular Friends are the important benchmark.

Final Thoughts

Friends and Trails are much easier to optimize once you stop asking:

"What is the rarest pet?"

and start asking:

"Which stat do I need right now?"

For Rebirth progression, prioritize XP.

For Ring farming, build around Rings.

For combat, switch to Damage.

Keep strong specialist Friends because they can also improve your Fast Friends, and use your single Trail slot to reinforce whatever activity you are currently doing.

The 2026 natural-leveling change also makes equipment progression less expensive than it used to be. Equip the Friends and Trail you want to develop, collect Chaos Orbs while progressing normally, and use Upgrade Machines only when faster manual progression is worth the currency.

Most importantly, do not invest heavily based only on rarity or an old tier list.

Sonic Speed Simulator continues to receive new Friends and Trails, so individual "best" items can change. The most reliable long-term strategy is understanding XP, Rings, Damage, Fusion, Fast Friend scaling, and specialized builds well enough to recognize a better item when you obtain one.
