"Mine doesn't." As far as he knows. He hasn't figured out weapon summoning yet, and while Balthier may think this is a grand time to try untested spells, Sephiroth isn't thinking of it. It's uncomfortable enough making use of this body's physical abilities.

Uncomfortable, that is, in that it doesn't feel as uncomfortable as he thinks it should. There's something easy about using this wing as a weapon, almost like muscle memory. But it would be worse to remain trapped here. He doesn't care what it looks like, he just wants out.

When they seem to have made enough damage to the barrier, he pulls back and slams a foot into it, hoping to kick loose enough of an opening.
