This is a raid boss, so bring as many OCs as possible and try to deal as much damage as you can until your defeated or defeat it. All damage will save across each remix/battle, EXCEPT THE SHIELD. -That's kind of it, since @DarkDragon838 controls the hp bar, the only way of being op is being impossible to hit or invincible.
