Hn.. well actually all he really needs to do is inject his torso, and legs, and other arm.. and then he'll be the Hulk only flesh colored..
With a tiiiiny little head. Which, I think, would be extremely awesome.
And then all we'd have only one more injection to go before... RULE THIRTY-FOUR. (hey, that rhymes)
Seriously though, I thought the arm was hilarious. I'm loving Dr. Wright's ineptitude right right now. Is he going to be a recurring villain, or was he only here to introduce us to Coldfire? It'd be a shame to be done with him so quickly...
