Mutant Seagull is one of the three animals that Dr. Animo mutates in the episode "Divided We Stand". It is first animal he mutates and uses in the episode. Before the seagull was mutated, Dr. Animo trained it to bring him the components he needed to build a new Transmodulator, and once he rebuilt the device Animo mutated the seagull and rode away from the prison on it. The seagull was defeated when Max Tennyson used his jetpack can push the seagull into the sea, The seagull was not seen emerging out of the ocean, It is most likely that the seagull drowned.
Its main use was to capture and keep an eye on Ben, but it was defeated alongside the Mutant Squid by Upgrade.
Three Mutant Seagulls appeared in "The Widening Gyre".
- In Resident Evil 5, when a Majini is defeated, it will make a scream similar to the mutant seagull from "Divided We Stand".
