Brawl Stars has never shied away from gut-busting chaos, and the Mutation system is proof. These limited-time abilities pop up during the Godzilla City Smash Mode and turn ordinary Brawlers into absolute menaces. Players unlock them through Monster Eggs, which also hand out other goodies. In 2026, the same 40 Mutations still get plenty of love and salt from the community. This tier list takes all 40 limited-time abilities and sorts them from the ones that make enemies run for the hills to the ones that barely move the needle.

One thing to keep in mind: Mutations only work in Godzilla City Smash Mode. Outside of that, they are about as useful as a screen door on a submarine. But inside the event, a good Mutation can turn a match into a 3v2 before the enemy even knows what hit them.

🔥 S-Tier: The Cream of the Crop

These are the absolute best Mutations in Brawl Stars. If a player rolls one of these from a Monster Egg, they should count their lucky stars.

  • Gray – Six dimensional doors at once make Gray the sneakiest Brawler in the mode. The real kicker is a glitch with his Walking Cane Gadget that can drag Godzilla players into unescapable spots. It is basically a free numbers advantage.

  • Meg – Two extra projectiles outside her mech means her Super charges constantly. She rarely leaves mech form, which makes her a certified pain to eliminate.

  • Eve – Between her Super, gadgets, Star Powers, and Mutation, Eve can spawn a literal army. Single-projectile opponents simply run out of ammo trying to clear everything.

  • Hank – His Super goes off every time he takes damage, causing pure mayhem in both close and ranged fights.

  • Carl – A faster Tailspin and pickaxe speed turn Carl into a wrecking ball. He can destroy buildings and reposition across the map in record time.

  • Ruffs – Extra bounciness on his main attack makes the map look like a bullet-hell game. Walls stop being cover when Ruffs is around.

  • Rico – The same bounce treatment as Ruffs makes Rico even more lethal than he already is. Players can sit back from safety and still melt buildings and enemies.

⚡ A-Tier: Almost There, And Still Scary

A-Tier Mutations are not flat-out broken, but they punch well above their weight. Anyone who says these are weak has not been on the receiving end of a good Tick or Surge.

  • Tick – Mines, Hypercharge, and Mutation make him a nightmare. He stays squishy, though, and his mines are not great at bringing down buildings fast.

  • Sprout – An extra Seed Bomb helps from long range. The splash damage also chips away at buildings.

  • Melodie – Two extra notes orbiting her body keep close-range Brawlers honest. If they do not wait for the notes to vanish, they might just get deleted.

  • Ash – More Little Helpers distract single-projectile Brawlers and give Ash extra time to rush or sweep buildings.

  • Max – Unlimited ammo lets Max keep pressure up forever, charge her Super nonstop, and boost teammates around the map.

  • Brock – An extra rocket on each shot adds width, damage, and AoE to an already explosive kit.

  • Angelo – Two extra projectiles on a fully charged attack can wipe several opponents. The lack of healing while aiming keeps him out of S-tier.

  • Gale – A wider attack is a death sentence with Freezing Snow. Slowing enemies down and pushing them away becomes laughably easy.

  • Poco – Taking damage now heals Poco, which is wild. Pair him with tanks and they refuse to die.

  • Stu – A permanently charged Nitro Boost means Stu can dash around like he had one too many energy drinks. It is great for map control, but over-dashing can put him in bad spots.

  • Surge – Party Tricks instantly brings Surge to Stage IV. Once there, he becomes one of the strongest Brawlers in the game.

✅ B-Tier: Solid, But Situational

B-Tier is where solid Mutations live. They can absolutely pop off in the right hands, but they are not automatic win buttons.

  • Colt – More range and destruction. A good Colt can make this look S-tier.

  • Spike – Extra needles add chip damage against enemies and buildings.

  • Bea – Rattled Hive helps with map control, but it can be dodged in open areas.

  • Bonnie – Extra projectile in Clyde form and a stunning Star Launcher make her dangerous.

  • Piper – Another projectile can one-shot many enemies from range.

  • Pam – Unlimited ammo is nice, but her slower speed means Max outshines her.

  • Shelly – Double shotgun blasts make close-quarters combat even more lopsided.

  • Lola – A second Ego adds extra damage and can be used as cover.

  • Janet – Faster Super charge and extra bombs make her deadly from the sky.

  • Grom – The X-shaped Super is almost impossible to avoid and wrecks buildings.

  • Mandy – An extra Sugar Ray across the map makes snipes even harder to dodge.

  • Crow – Returning blades keep enemy healing down, though Crow himself is not a building destroyer.

🟡 C-Tier: Decent On Paper

These Mutations look better on paper than they are in practice. They can work, but players will need to work for it.

  • Bo – Unlimited mines sound crazy, but he cannot cover the map as fast as people expect. Still decent with Snare a Bear.

  • Squeak – Extra Super projectiles and faster charge help, but it does not make him an optimal pick.

  • Nita – A second Bruce is cool until Godzilla or Mutated enemies blow it up immediately.

  • El Primo – Faster travel, extra HP, and faster Super charge sound great, but the destroyed maps leave little cover for him to close distance.

  • Belle – Shocker splitting into five attacks feels more like a 5v5 tool than a 3v3 game-changer.

🟠 D-Tier: Pretty Weak Sauce

These Mutations do not do much to help their Brawlers win matches.

  • Penny – An extra cannon can work if placed well, but it shoots too slowly and gets blown up easily.

  • Buzz – More Super range is okay, but he needs perfect aim and gets no help after latching on.

  • Rosa – Spawning bushes is nearly useless because they get destroyed instantly, and the maps have little natural shrubbery.

❌ F-Tier: Bottom Of The Barrel

These two Mutations feel more like minor Star Powers than actual game-changing abilities.

  • Frank – Extra movement speed and health sound fine, but increased damage from other Mutations makes the HP buff meaningless. Breaking walls can also backfire.

  • Leon – Two clones after Smoke Bomb feels like an extra gadget, not a Mutation. Compared to everything else, it lands at the bottom.

🎯 Final Verdict

All 40 Mutations have a home in Godzilla City Smash, but some are clearly built different. Players should not treat this list as law, because team comps and play styles can make lower-tier Mutations shine. The real goal is to crack open as many Monster Eggs as possible, score rewards for the club, and enjoy the limited-time mayhem. Whether someone mains Gray or is stuck with Leon, the best play is to experiment, adapt, and send Godzilla crying back to the sea.
