A trap could evolve from a Bakugan. Prove me wrong. After all, they are called Dart Drago and Metal/Spyder Fencer, and Triad [El Condor[/i]. Also, the feet were a bit different, AS. Also, if it had horns, then why didn't they go up? In the show, when a Bakugan stands on a gate card, it should open up all the way.
Because it's a cheaply animated cartoon? You honestly think they do everything right all the time? Ha!"Also" your logic is off...My understanding is that Metalfencer and Spyder fencer are completely different Bakugan. Rivals of sorts. One belongs to Spectra, The other "belongs" (this is an assumption because of Maxus Drago) to Dan...Just because two Bakugan are alike doesn't mean they are an Evolution chain. That being said... things like Spin Drago, Spin Ravenoid, Dart Dragonoid and quite possibly Boost Ingram are not part of the Evo chain either. Rather they are sub-species (dart) or even more simply... Just GIMMICKS(spin).
