Pidgeot

Speedy brought his Pidgeot and his Golem along to run the Kalos Pokémon League. This is where Pidgeot's abilities shone through, becoming his third ace.
Through additional training, Pidgeot can resist Electric-type moves, causing them to not be super effective. They now do regular damage.

Design Differences:
Physically, this Pidgeot doesn't seem all that different from other Pidgeots, except for the fact it's crest is quite a bit shorter.
