Pokemon Mega Venasaur

Take a look at one of the first new amazing Mega Evolution Pokémon, Mega Venusaur-EX (2/146)! This Pokémon evolves from Venusaur-EX. When you evolve it, your turn ends—so choose your timing wisely! Mega Venusaur-EX has an outstanding 230 HP, making it incredibly difficult to Knock Out. Plus, its Crisis Vine attack is unbelievably powerful, doing 120 damage and leaving the opponent’s Active Pokémon Paralyzed and Poisoned! With a withering attack like Crisis Vine, Mega Venusaur-EX is simply a phenomenal Pokémon.
