ATK

ATK/Attack is amount of damage a hero does to a enemy,

ATK is on both sides which on your side is good as it can defeat the enemy, but it can be bad as the enemies can KO your allies

there is only 4 ATK damages, these being 20, 15, 10, and 5,

Attacking is the only way to defeat a enemy, but it is also the only way to KO a ally

You can attack everybody with an attack, Even your own allies which I wouldn't recommend.

Enemies usually die when being defeated, but a enemy that will join you after Faints instead,
