P.E.N.I.S. were the most pathetic Phoenix Avatars..........ever, and that's saying something seeing as how the PF was wielded for years by Rachel Summers.
IMHO, he could clear it. Hell, if this fight actually went down in a comic, I think the PF would leave P.E.N.I.S. and merge with Sentry (like it did with the Madelyn clones).
