WPM has claimed his source has told him the following English names for the Pokémon:
Gogoat -> The same
Yancham -> Panchum
Yayakoma -> Fletchling
Elikiteru -> Helioptile
However, I still think WPM (or at least his source) is full of crap. Why? Because if Gogoat's name is the same...why was the "basis" for his source being "legit" the fact that there's an electric-type move that heals you as it does damage and not y'know...GOGOAT?
