Under other circumstances Magnus might have been impressed but as it was he was caught off guard and incredibly annoyed as he felt the seismic energy wash over his barrier and shatter it. The electromagnetic shield absorbed most of the initial impact but what was left was enough to knock him back, break his concentration, and the girl who attacked him got the helicarrier dropping several more feet for her efforts. He struggled to hold it again even as he reformed his personal shield, wondering whether this young woman was superhuman or mutant. If it was the former then this was such a prolific waste and she was a fool- he could have used someone with her kind of power for the Brotherhood. Wasted potential.
Once he'd regained control of the vessel again he turned his focus on the idiot who'd dared to attack him. She was passionate, he'd give her that. And now she was going to regret it. Magneto tilted his head and he smiled. One of the jets on deck jerked into motion, dragging across the helicarrier straight at the girl, knocking several people off the deck unfortunate enough to be in its path.
