Pokédex entries

What each game says about it, in the games' own words.

Black	Countless charred remains mar the landscape of places through which Thundurus has passed.
White / X / Omega Ruby	The spikes on its tail discharge immense bolts of lightning. It flies around the Unova region firing off lightning bolts.
Black 2 / White 2 / Y / Alpha Sapphire	As it flies around, it shoots lightning all over the place and causes forest fires. It is therefore disliked.

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
