In Co-op mode, Seagull's REC stat is increased from 4 to 5, due to its base ATK of +1. Seagull's passive does not visibly change; however, part of Seagull's passive does not function:
- Seagull does not lose 1/4 stars when KO'd in battle, but loses 1/8 stars like any other character.
Seagull's Hyper, Jonathan Rush, does not visibly change in Co-op, but has a slightly different effect. The Hyper can only target enemies and not players, but otherwise functions the same as in Normal mode.
Seagull's passive and Hyper are unchanged in Bounty Hunt mode.
Seagull's base stats give it 42 starting stars and a discount of -5% at shops.
