At first the robot is upset that it can't hit her with its attacks, due to her powers, which also mess up its calculations and cause things to be unpredictable. Then, after coming close to knocking her out with some gas, her hide gets saved by Cable, then Shatterstar. Still though, she survives for a long time on her own, and this IS Nimrod.
-They need to hold back a lot because they don't want to hurt their team. Shatterstar goes after her, she disarms him of one sword with ease (which few people, if any, have ever done), but gets stabbed in the shoulder. It also seems very odd.. in the last two panels, she goes from parrying a blow, to having her sword stuck in the ground, with her lieing down defenseless...
-Also note her pain threshold. She tells Nate to carry on, she's been hurt worse, she'll be fine.
-In a scenario where each member of the team is given a chance to live in their most desired situation (for instance, Warpath was with his late brother, herding bison), Domino just wanted to be in the dark, alone and away from her past.
