Could you/your characters take my characters in a fight?

Finn can use magic, has Dragonborn powers that can do all kinds of deadly things, he uses knives and he fights dirty, so I wouldn't recommend it

Anders also uses magic, including fire, ice and lightning, or he'll just whack you with his staff if you get too close. Or Justice will tear you apart, literally. So wouldn't recommend that either.

Kurt you could take in a fight, because he's bad at it. However, he's strong enough to throw someone through the air and he bleeds acid, so that's something to keep in mind.

Thrawn is not someone you want to fight either. He's really good at hand-to-hand combat, is stronger and slightly faster than a human, and chances are even if he starts losing, he prepared a backup plan to ensure he wins.

Thrass can't fight, so you've probably got good odds with fighting him

Vector is also stronger and faster than a human, and he carries a big staff with him that he uses to fight with.

Scarecrow can't fight for peanuts, so chances are a fight will have him starting off by just poisoning his opponent with fear toxin

Would not recommend fighting Venom. He's huge, he has teeth, and he only holds back because of Eddie. Eddie minus the symbiote, you might be good.

The Grand Inquisitor is an expert in lightsaber combat and he has the Force, so unless you have the Force too, you might just want to run
