his shield has repelled mjollnir in the past, and mags gave the entire avengers a good run. bloodlust, i still go with thor, but i don't think it would be easy . . .
and it is ACTS of vengeance, and i don't THINK loki and mags squared off. loki didn't reveal himself until the last part in west coast avengers, and mags wasn't there. if they did meet, i don't recall it, and would love for someone to point it out. could you have been thinking about loki fighting apocalypse? THEY briefly fought in the acts of vengeance . . .
Magneto can rip metal from the earth and hurl it as BBs towards Thor rending him blind for as long as he wishes. At the same time he can create thousand pound spikes and send them flying at Thor's Back, Neck, Head... He can wrap steel around his "boys" and squeeze with incredible force. He can do many many many things at the same time. Don't underestimate Mags!
No way! I'll continue...
He can wrap cable around Thor's throat... weld his legs together ... send liquid metal into his ears, nose, eyes and shove a ton of it down into his lungs and guts. Then he can work that metal from the inside turning it into sharp jagged blades and zipping them around ripping things. Meanwhile he's spinning him all over the place in circles, crashing him into things, still throwing sharpened metal spikes at him, grinding him into the core of the earth...
I think Mags can do better than 4/10!
