>>39382751Bulbasaur is so good that it doesn't need mega anyway.
Chlorophyll makes it a beast under the sun.
Thick Fat makes it have only 2 weaknesses and too much bulk that literally nothing in the game can stand on its way if it has a good moveset.
Charizard is completely garbage and useless without megas.
Charizard X, only good if you want physical moves.
Charizard Y, the better option but still die from rock moves.
and since this is Gen6, there are tons of great Fire Pokemon but there aren't much good Grass pokemon.
