Suggested by Destroyer Roulette is a skilled entrepreneur who did a good job of kidnapping pretty powerful DC characters. That said, she did this with tech and not physically. She has no real powers and being a good hand to hand fighter is not nearly enough to take down a Kaiju. King Ghidorah can just keep firing off his energy blasts and eventually one of them will land. Roulette really has no good defense against such a strategy and will ultimately end up going down. This is not a fight she can win. King Ghidorah wins.
