The more I look at the artwork, the more I'm drawn to the xray of the arms. I see the regular looking arm bones. Makes me wonder if TOWTMs is an actual Zed or not. He's "more than human" for sure (jumping ability, running speed, ability to take punishment...).

I wonder if we don't have some sort of "Super Soldier" thing going on here. The original formula worked once but the creator was killed before it could be completely reproduced. Now, in an attempt to replicate it, the <insert organization nobody likes> has unleashed a form that creates more powerful humans - but at a cost!

Unforeseen problems include the infection aspect, loss of control of creations, evil genius alterations of formula for more nefarious purposes....

Please ignore the ramblings of the crazy old coot in the corner....
