yo ok so this is how u get a level 100 buterfree e-z. ok so then you capture a metopod in the forest. then you give him lucky egg so he will get 2 X xperiance. then you battle the elite 4. IMPORTAT: DO NOT EVOLOVE HIM OR HE WILL LEVEL SLOW. then you battle the elite 4 many times then when he is level 99 EVOLVE HIM NOW BECAUSE IT IS YOUR LAST CHANCE. the level up 1 more time.

CONGRADULATION you have a level 100 butterfree e-z!!!!!!!!!!!!!!

it is really good one time i beat the elite 4 with it alone any i only used 3 potions!!!!!!!!!!!!!!!!!!!!!!!!!!
