Oliver Sullivan
Subway
Skills: Molecular Oscillation
Thankfully for Oli, he was able to keep himself from phasing through things, but this fight was still going to have him at a major disadvantage if he had to be spending this much mental effort to not pass through things. That meant that this had to be ended as quickly as possible, so the best avenue for that was probably getting that armor off of Other!Cass, and the easiest route to accomplish that would be to simply phase it off of her. Closing the distance between himself and his alternate universe boss, he went to try to rip it off of her, only to walk straight through her.
Oli had another option though, he could just cut off the armor with his trusty flaming laser sword. Giving it a flourish, his fingers slipped, and accidentally turned it on while spinning it about, resulting in the blade cleanly cutting through the arm of the Cass in front of him. "Oh fuck." He said, as the arm fell to the ground, the metal clanging to the ground. "Shit, I'm sorry, I honestly didn't mean to- I'm sure you can reattach that." He said, the shock and survival instinct telling him he needed to phase, and so he did, too successfully in fact, falling out of the train entirely.
