Only can be learned when the victim.. I mean Pokeman... Err wait.... Pokemon learns every single move and becomes level 9000. Then Chuck Norris will appear and magically teach your Pokeman Roundhouse Kick.
It does infinite damage and the Pokeman its used on will never be able to be healed, it will forever stay in the fainted state. It can hit any types, even ghost. It also has infinite Power Points.
