This may sound silly,lol but i thinking she may be able to put up a good fight,him heres why, she can withstand attcks via magnetism by using her forcefeild, use her telekenesis to throw object at him, or if he throws something via his magnetism maybe she could redirect it back and is it possible to remove his helmet via telekenesis and then use her telepathy to bring him down. How much weight can she lift via her telekenesis, and how much power can her forcefeild hold.
