Okay, all of you people ragging on Mega Manectric stop for a minute.

Manectric is based on the Raiju, the same basis for Raikou. In particular, it is based on the creature's ability to take on the form of a wolf.

The Raiju had the ability to travel as a bolt of lightning. It was CREATED to explain the concept of lightning.

Learn to freaking design theory, morons. Making Mega Manectric look like a giant furry Lightningbolt is clever as fuck.
