Aquaman vs Winter Guard

Aquaman

vs

Crimson Dynamo (Bukharin)
Red Guard (Nikolai)
Darkstar
Ursa Major

Fight on New York.

1. No TP.
2. All out battle.

Nikolai would be Vanguard.

Darkstar wins (unless Aquaman gets lucky with TP). People seriously underestimate her because writers ignore most of her powers. She encases him in tar-like Darkforce and that's that. If she wants she can even suffocate him with it.
