Mutation Alpha: Inverts effectiveness of this Pokemon's stab moves.
(So a grass move would hit grass, fire, flying etc super effectively and not be effective against water, rock, ground etc)
Mutation Beta: Inverts effectiveness against this Pokemon's typing.
It's basically the rules of the inverse battles split into two abilities. Offensively and defensively. Could make for an interesting shake up. The names are just for show....they could be anything that sounds remotely cool or mysterious.
Berserker: Increases attack power by 75%, however has a chance to hit itself or team members.
Entangled: Lowers speed by 25%. The ability of a Pokemon that make physical contact with this pokemon changes to the entangled ability. Grass and Bug types are not effected.
Frostbite: Lowers Attack, Defence, Sp. Attack, Sp. Defence and Speed by 10% (or 5%, not sure...) each. Deals minor damage each turn. The ability of a Pokemon that make physical contact with this pokemon changes to Frostbite. Ice types are unaffected.
Last Laugh: When this pokemon faints, the held items of the opposing team are shuffled around randomly. Does not work if the pokemon faints due to friendly fire, burn, poison or weather effects. Works if the pokemon faints due to a physical or special attack from an opposing pokemon or if it faints due to a move such as Stealth Rock.
Some of them might be OP but I figured Grass and Ice types could use a boost.
