Whats up with this Cobalion

[Noxe]

Received it from someone, doesn't work on wifi.

Is it excedingly good?

If so it might have been altered and be considered illigal by wifi

It's been badly generated by someone who looked Cobalion's Met Location on Serebii, not knowing that it's imprecise.

It shouldn't be 'Mistralton Cave', but 'Guidance Chamber' (which is a part of the Mistralton Cave). He shouldn't know Light Screen either, since that Move isn't even in his moveset.

As far as Pokémon legality is concerned, there are no exceedingly good Pokémon. A Pokémon either is legal, or isn't.
