Daisy will be fighting the Inhuman primitives. They've got super strength and stuff but she's going to fight them hard and quake 'em. You might see her get some lift off too. Not exactly flying but BOUNCING. Or free-falling. That sounds nicer at least.
Matt will fight with the Defenders group and will probably get back to back with Elektra more than once. That just normally happens! Sais go well with fists. Um, right? Matt won't be killing anyone but he'll be trying to stop them like omg.
Killian will be focused on trapping the fuck out of that shadow with Bae and Emma. They did it with a coconut and a candle last time. I say they get somebody's sweet ass Howdy Doody lunch box.
Erik's good in a fight. Besides ripping stuff to pieces, I think he'll probably thread some scrap through a sentinel and use it as a puppet. Up to the mods whether it stays or not.
Belle is NOT cool with fighting, even though she's been learning hand to hand at Logan's gym. She'll go help Dr. Frankenstein with the medical stuff! That, at least, she can do. She's cool headed and bandages prettily.
Stefan doesn't have his sweet ass vampire skillz anymore, but he's still good at fighting hard. Also he'll stick close to his friends so they can help just in case anything gets super stressful.
