Mega Cat (メガにゃんこ mega nyanko) is an event enemy that appeared in Final Boss Advent!? Event and one of the Monthly Event All-Stars Stage, Elite Corps (Insane). When the stage is beaten, the player will receive the special cat, Singer Cat. In Battle Cats POP, Singer Cat is a super rare cat you can get through the Rare Cat Capsules.
The next schedule for this event is unknown.
It has extremely long range (longer than Nerd Cat and even Assassinlan Pasalan) and deals very high damage. However, it has very low health and has slow attack rate and movement speed. Oddly enough, this enemy is metal.
Spawn non-stop normal Cats and/or fast attackers like Mr. or Cow Cat and after multiple attacks, the boss will die and you will win the battle.
