Get Fishi through the Summer event
Get Fishi from the Sunny Star capsule or Summer event summons while Fishi is listed in the Summer pool. To evolve it into Fishi (Obsession), you need the base Fishi, one Captain's Hat and 7,500 takedowns credited to Fishi.
Evolution makes Fishi a stronger Physical/Water damage-and-control pick, adding Attack, Sightless Maw and Drowning. Prioritize it if you want help controlling tougher waves, and plan your team around that role.

| Fishi (Obsession) | Gains +25% Attack, Sightless Maw and Drowning. | Evolve Fishi with one Captain's Hat and 7,500 takedowns credited to the unit. |

Read the Summer summon odds correctly
The Summer event summon screen shows a 0.25% overall Mythic-unit rate and a 33.3% share for each of its three featured Mythics. That featured share is not a 33.3% chance to receive Fishi on every summon.
Check that Fishi appears in the pool before spending Summer Pearls. Once you have the unit, consider reserving Pearls for Captain's Hat before chasing more summons, so you can move straight toward evolution.

Evolve Fishi into Fishi (Obsession)
- Keep the base Fishi you want to evolve, then work toward 7,500 takedowns attributed to that unit. Check Fishi's requirement before spending time on another evolution grind.
- Buy one Captain's Hat from the Summer Event Shop for 5,000 Summer Pearls. This is Fishi's required event item, so check its name before purchasing.
- Take Fishi to the Evolve area after completing the takedowns and obtaining Captain's Hat. Select Fishi, inspect its requirements and use Evolve when they are met.
For this Summer evolution, follow the event-item and takedown requirements rather than a standard Star Fruit recipe. Make Captain's Hat and Fishi's own takedowns your priorities.
What Fishi (Obsession) adds to your team
Fishi (Obsession) deals Physical/Water damage and combines damage with control. Evolution grants +25% Attack alongside Sightless Maw and Drowning, with Drowning applying stacking sanity loss and stuns.
That combination makes the evolved form worth considering for tougher waves. Choose it when you want damage backed by disruption, and judge the investment against the role your current team needs most.
Fishi and Water Goddess evolution questions
- I got Fishi and Water Goddess from the Summer event. How do I evolve them?
- Each needs an event-shop item and 7,500 takedowns. Fishi uses Captain's Hat, while Water Goddess uses Lotus Scepter. Check each unit separately in the Evolve panel so you purchase the correct item and track the right requirement.
- Does buying Captain's Hat finish Fishi's evolution requirements?
- No. You also need the base Fishi and 7,500 takedowns attributed to it. Captain's Hat satisfies the item requirement; complete Fishi's takedowns as well, then use the Evolve area.
