I... I just OHKO'd Nuclear Actan...

[Dragonstrike]

*Sigh* And here I thought that the Devs re-added an interesting Nuclear Legendary for people to play around with, or just collect at the very least. I mean, story wise it doesn't make much since Actan purifies itself from the corrupting radiation, but I'd still like to see the glowing green brute implement someway in the game, as Corrupt Legendary Pokémon sounds like a really neat concept! Maybe a future Mystery Trade event in the future could provide this? Nintendo has done similar for some of its Legendaries , so why not in this case too?

Well, you can still catch it in version 1.0, technically.  Having a N-Actan that knows Inferno and Nuclear Slash is certainly interesting...

I'm not really a big fan of Nintendo doing the whole thing with Shiny Locking legends and mythicals ever since gen 5 and then giving them out as event only later, and only having them be available as in-game shinies if they appear in the wild in a game where they aren't significant to the story.  Sure it makes no sense for that Rayquaza you just saw in the overworld to be black instead of green, but come on, developers...
