Anime Adventures Fishi in our tier list
S Players report each hit adds 10% insanity, and a full meter costs the target 35% of its max health as true damage plus a 3.5-second stun. A hit that grows with the target is worth most on bosses, so on paper Fishi belongs in S. See the full Anime Adventures Tier List.
Anime Adventures Fishi strengths and weaknesses
Strengths
- The full-meter hit scales with the target, so it keeps its value on bosses and tough enemies (35% of max health in the creator videos we watched).
- The 3.5-second stun that several videos show at full insanity buys time for the rest of your lineup.
- Fishi gains from Water Goddess, since the creators we compared say its attacks count as water damage.
Weaknesses
- The payoff takes time: at 10% per hit, the big hit needs about ten hits on the same enemy, so weak enemies may die or walk past before it ever lands.
- Fishi sits on a limited banner at about 0.083% per summon, and we have not confirmed whether it can be obtained after the event ends.
Our take
- Our read: Fishi is a boss answer first. The max-health hit does the most work where health bars are largest, so we would place it in boss-heavy stages before wave clearing.
- Do not treat pity as a Fishi guarantee. The 400-summon pity promises a Featured Mythic, and all three Summer Mythics are Featured, so it can land on Water Goddess or Armored Crusader.
How to get Fishi
Fishi is one of three Featured Mythics on the banner that came with UPD 21 and its Summer 2026 Event. The banner gives Mythics a 0.25% rate and splits it evenly between Water Goddess, Armored Crusader and Fishi. We worked that out to about 0.083% per summon for Fishi.
Each summon costs 150 SummerPearls. The banner guarantees a Featured Mythic within 400 summons, but that pull can be any of the three, so pity is not a sure route to Fishi. Any unit from this banner has a 1% chance to be Shiny.
The summon screen flags the whole banner as a time-limited one with exclusive units. We have not confirmed whether Fishi can be obtained after the event ends. See our anime adventures summer event guide for the rest.
What Fishi does
Fishi builds an insanity meter on whatever it hits. In the creator videos we watched, each hit adds 10% insanity and the meter keeps stacking. When it fills, the target takes 35% of its max health as true damage and is stunned for 3.5 seconds.
The creators we compared also say the max-health hit works on bosses, and that bosses are where it does the most. On paper, a boss with a huge health bar loses the same share as a small enemy, so the damage grows with the target. That is why Fishi sits in S on our anime adventures tier list.
The trade-off is speed: the big hit only comes after about ten hits on the same enemy.
Best traits for Fishi
Our picks on paper, based on the effects shown on the in-game Trait Chances screen:
- Divine: lifts damage and reach by a fifth each and trims the cooldown, and faster attacks fill the meter sooner.
- Celestial: a small damage and range bump, plus a fifth of every hit repeated as true damage.
- Reaper: a general damage boost with a larger one against bosses, which is where Fishi earns its place.
- Unique: quadruples the damage line, yet the game lets you field just one unit carrying it, so save it for a lone Fishi.
We have not confirmed whether damage traits raise the 35% max-health hit itself. Our read is that they raise the regular hits that build the meter. Full odds are on our anime adventures traits page.
Fishi evolution
Fishi can evolve. The Event tab of the quest menu has two quests that name it. Fishi is one of five names on them; evolving any single one clears Sunny Evolution, and three of them clear Sunny Evolution II. Two creators report the recipe: the Captain’s Hat, bought with Summer event currency at Nami’s market, plus 7,500 takedowns, and one of them adds that no Star Fruit is needed. Two sources name the evolved form Fishi (Obsession); we have not seen that name in game yet, and we have not confirmed what the evolution adds. Our anime adventures evolution guide covers the general steps.
Other new UPD 21 units

Anime Adventures Fishi FAQ
Is Fishi good in Anime Adventures?
Yes. Fishi sits in S on our list. In the videos we compared, its hits build insanity until a full meter deals 35% of the target's max health as true damage, and this is strongest on bosses.
How do you get Fishi in Anime Adventures?
Summon on the Summer 2026 Event banner. Fishi shares the 0.25% Mythic rate with two other Featured Mythics, which works out to about 0.083% per summon. Pity at 400 summons gives a Featured Mythic, not always Fishi.
What does Fishi do in Anime Adventures?
Several videos show each Fishi hit adding 10% insanity to the target. At full insanity the target takes 35% of its max health as true damage and is stunned for 3.5 seconds, and the attacks count as water damage.
What is the best trait for Fishi in Anime Adventures?
In our ranking, Divine is the top pick for its damage, range and cooldown together. Celestial and Reaper come next, and Unique fits if you only place one Fishi, since Unique allows a single copy on the field.
Is there a Shiny Fishi?
The Summer banner shows that any unit has a 1% chance to be Shiny, so a Fishi pull can come out Shiny. It uses the same banner and the same 1% chance as the other units there.
Can Fishi evolve?
Yes. The Sunny Evolution quests name Fishi as one of five units to evolve. Two creators report it takes the Captain's Hat from the Summer event market plus 7,500 takedowns, and two sources name the result Fishi (Obsession), a name we have not checked in game.
