Absolutely do not believe that Basara's bey is Bahamut. His last name translates to emerald green dragon and that's not at all what Bahamut is. I'm hard predicting his bey to be named Basalisk but that's getting into speculation.
I really dig the idea of attachments for belial based off each bey. Can't help but think belial is gonna look like a mess with all of them attached but hey it might be a really good bey.
Final thing: It looks like there's a straight up picture of Fafnir on the picture we have but I haven't seen a spread of Fafnir itself yet which is really weird. Maybe we'll just have to wait until TT themselves show off Fafnir
