You can't breed Thunderbro but you can catch it roaming in white. I mean maybe you could Ditto breed but I doubt it (tell me if it works o_0)

Well I really want to breed a legal thundurus but I don't get how lol

Oh okay that explains it.... (*faceplam*) I would still go for it I think.

No Lol I meant breeding wise

New Thundurus? You mean LO+ 4 attacks? Hmmm it's actually outclassed by NP but it's usable you can also use legends in the new games if you were wondering.

Saw your really solid rmt in the forum but I have to ask how did you make a new thundurus? I really want to try him out but I'm not sure about making legendaries in the new games
