Crazed Titan Cat (狂乱の巨神ネコ Kyōran no kyoshin neko, Frenzy Titan Cat, Frenzy Giant Cat) is Titan Cat's counterpart that appears in Crazy Cats (Insane). Completing the stage will unlock the cat unit.
It looks like a regular Titan Cat, but has a blank stare, black fists, a tattoo over its right shoulder, and a purple aura surrounding it. It attacks by charging up a punch, then smashing the ground.
Occasionally (it's random, but happens about every 8-12 attacks), his punch creates a shockwave that spans a little more than 1/3 the battle field. Most cats will die in the shockwave, and the ones that do survive may be slowed for a long time. However, the shockwave does not damage your base.
He has a 100% chance to knock back all cats units, and a 40% chance to slow all your cat units for 200f; that is, if they survive the attack.
