Absorbing Man most likely, unless Hellion can win the quickdraw and snap Creel's neck right off the bat before he gets a chance to transform... which is unlikely.
If not, then Hellion may be able to keep Creel in a forcefield for a while, levitating and prevent him from turning into anything other than air...
But eventually Hellion will tire out... and once Creel gets to touch the ground, things will turn south for Hellion very quickly.
