I don’t have my PC for PKHeX and I only have a previous thunderous I was working on. Is it worth trying it with Tornadus to get Landorus in BW and OrAs?
And why are the forces of nature name spellings so hard?
As far as I know, you can get Tornadus in OR, and Thunderous in AS, and if you have both, and you go flying in the sky, fly into the stormy cloud and you should find him, Tornadus and Thunderous can be found in the stormy cloud when Castform is in your party, sorry if I missunderstood the question.
