Xavin declined to allow himself to be thrown by a dead thing. It wasn't even a living enemy. But he didn't know how strong bone things were (Kree level? Lower? Higher?) but knew better than most that the Thing was not the strongest in the universe. Very strong and very tough... but enough? Who knew?

The bone thing was grabbing high. Xavin dropped the Thing's powerset, transitioning smoothly to the Invisible Woman's powers and his male human shape. A few invisible slashing fields would hopefully take off the creature's hands. If it couldn't grab, Xavin could go back to punching it without concern for his allies.
