See here to know how to classify Units.
The classification does not represent Units in their niches.


This cat is a very good placeholder for meatshields due to its very fast movement speed. It can also be spammed to easily take out Floating enemies such as The Face. Its DPS against floating is the same as its attack damage against everything besides floating if you have all treasures, because it does 4 times the damage with 4 seconds between each attack.

For a super rare this cat has insanely high damage and DPS against floating enemies, and its True Form increases that even more.

The first two forms of Swimmer cat are already amazing. They are able to counter almost all floating enemies. but their biggest threat being Bun Bun variants, as Bun Bun almost guarantees that they won't get a hit in, unless timed right. True form solves this small problem.

Before True form, you can make it so this cat can be very effective against Bun Bun variants if you stun lock them with Necromancer and/or Angry Delinquent. First have a stack of Necromancer's, and some Angry Delinquent's, once Bun Bun is being repeatedly frozen send out Swimmer cat's to score some huge damage! *note it is important to make sure you send out the Necromancer cat's and Angry Delinquents FIRST so they can stun Bun Bun before Swimmer is sent out, otherwise Swimmer will get killed.

This cat can also be used as a gap closer similar to Express Cat and Crazed Cow Cat.

True Form Analysis

PONOS has done some genetic modification!

  • Fishman Cat is an improvement over an already good cat unit. The health, speed, and damage was good enough for a True Form, but the most important thing is the range! Although it only increases by 30, this range lets it outrange Bun Bun and all of its variants (except Bun Bun Symbiote's shockwave, Mecha-Bun and Relic Bun-Bun), allowing for an easy win(most of the time)! This cat can also kill Crazed Bird Cat in around 20 hits at level 30! A hypermaxed Fishman Cat (Lvl 50) with all treasures can have a whopping 24k DPS against floating with around 96k damage a hit! With talents, this becomes 115K damage per hit! Add in the 2 combos Sister Act and Scantily Clad for even more damage: a huge 152K to Floating per hit! In fact, This can shred some floating enemies faster than most Ubers can! The Fishman Cat damage is actually very good against one shot enemy, like The Sloth, the Fishman Cat would do 3-4 hits, then die, then attack again. Its cost is pretty cheap, the same amount of Hip Hop Cat.
