Battle Of The Vultures

Okay, so here we go. If all the members of the Villainous Vultures were fighting to the death, who do you think would come out on top? I know there were some team switches so I'm gonna confirm which members I'm talking about. The original Vultures are the ones I'm referring to. So that would be Duncan, Heather, Gwen, Jo, Scott, Alejandro, and Lightning. So yeah, who do you guys think would win if all them were to fight to the death. Not to the literal death though, as a challenge. My money is on Duncan since he's my favorite character. Who do you pick?
