Roll Anime to Fight Mutations Guide (August 2026)
Mutations are special variants of anime fighters — the official game description lists "rare animes and mutations" as part of the core rolling loop. A mutated unit outperforms its normal version, which changes how you should roll, merge and spend Trait Shards. Here's everything verifiable about the system.
Known mutation variants
| Variant | How you get it | Verified by |
|---|---|---|
| Normal | Default roll result — no mutation. | Baseline for every unit in the roll pool. |
| Gold | Rolls can land Gold variants; several codes grant them directly. | Gold Kashimo (FACTIONUPDATE!), Gold Megumi, Gold Gyomei, Gold Kenpachi — all verified code rewards. |
| Diamond | Rarer than Gold — from rolls and top-end code rewards. | Diamond Tobi (NINJAUPDATEPART1!), Diamond Rengoku, Diamond Toji, Diamond Ulquiorra, Diamond Broly, Diamond Ace — all verified code rewards. |
Mutations and the roll loop
Every roll can produce a rarity (Common through Legendary and above) and a mutation variant on top. Luck bonuses affect what you pull, so mutation hunting is really luck stacking: codes with Luck Potions (SORCERERPART2! shipped two), upgrades on the Gold economy, and event boosts during Admin Abuse and update events.
What to do when you hit one
- Protect it immediately — keep it out of your merge fodder pool.
- Make it the merge target: feed normal duplicates into the mutated copy (merge guide).
- Spend Trait Shards on it — mutated units are the correct place for trait rerolls, since the variant plus trait bonus compounds.
- Compare before benching a code unit: an active-code Gold unit (like Gold Kashimo) is a guaranteed baseline; a rolled Diamond may still beat it. Check the tier list.
Mutation FAQ
What are the exact mutation odds?
Another Slop has not published official mutation rates, and no source we cross-check has verified them by data collection. We list mechanics we can verify and skip invented percentages — treat any precise odds you see elsewhere with skepticism.
How do I get Diamond mutations?
Two verified routes: roll with stacked luck bonuses (see the roll mechanics below), or redeem codes that grant Diamond units outright — the fastest guaranteed route while a Diamond code is active.
Do mutations stack with traits?
Yes — mutation variant and traits are separate systems. A Gold unit can carry trait bonuses on top, which is what makes mutated units the preferred Trait Shard targets.
Should I merge a mutated unit into a normal one?
No. Keep the mutated copy as the merge target, never the fodder. Feeding a Gold or Diamond variant into a normal copy throws the variant away.
