Pokémon X and Pokémon Y

Mega Manectric is still fugly as f'uck. Same with Mega Scizor and Mega Heracross. Mega Gyarados is passable. Neither the art, nor their sprites, nor their model makes them any less fugly or redeemable.

Mega Scizor is clearly too much for you to handle, casual.

Though, I'll give you credit in that you can tell they ran out of ideas when they got to Heracross and Manectric. I think they came up with a list of mons to give Megas to but didn't necessarily have any ideas for some of them.
