So we have good Mega Pokémon, the best Mega Pokémon, and the most OP Mega Pokémon. But what are the worst Mega Pokémon, or Pokémon that were a missed opportunity when they mega evolved. What Mega Pokémon needed a Mega yet it didn't really help them as much as it could have. For me I have 3 Choices but I will only list the Pokémon, and not why, I rather have you guys explain your reasoning behind why you felt some Mega Pokémon were just missed opportunities, whether it be the abilities, stats, or design(only include this with the other two). My choices are Abomasnow, Ampharos, and Heracross. What about you?
