She seems very confidant. Though with her track record she seems to have little to fear.
I have taken notice that besides maybe Fracture and getting caught off guard by a (thankfully) childishly-minded hypno supervillain, Fusion has never really been in any serious danger in her super-career. Even with the supposed "Hero Holocaust" member Thermo he felt like a pushover for her.
Its not a complaint, mostly an observation of the story so far and how she's fared. I do wonder how Fusion will react when she faces a foe she may not easily take care of in 1-5 pages.
Remember, the mission is slow them down, maybe stop them until the refugees are across the border. Try to avoid actions that injure, incapacitate or kill. Hmm, maybe they are just there to pick up the helicopter crews that you managed to strand.
she seems a bit overconfident, if she doesn't get knocked down a peg then it could mean that she will learn to use her power a bit much to try and do what she thinks should be, which is a slippery slope. i have confidence that she will meet her match though and be humbled before too long.
