Hey! Sorry I took so long to respond, been busy playing
Yeah Ononox is a perfectly sensible romanization, but I believe the *official* one (which doesn't always reflect where the name is derived from) has been confirmed to be Ononokus.
I'm Dawnfaligi, also from VGD. Here at Serebii, unlike at VGD, are full of some members who know what they're talking about when it comes to Nintendo games like Brawl, and they don't say stuff like Nintendo abandoning the hardcore and know how screwed up the fanbase is.
