He's not a robot, Just fyi lolz I w I)
He's a goo/latex skinned, Flight Challenged, Zombie/vampire/General Cannibal
Dragon but not a robot. That would just be ridiculous. T wT)

Still, though, I updated his visual look here, Really going into how I want him to come off and the general feel/vibe of the dood.

Got major inspiration for the skeleton type deal with this one character Eliza from a game called Skullgirls. https://youtu.be/krbFgDzlx44?t=3m45s

Gave it's own unique spin on the skin/goo tones and complete goo look with a skeleton to by over Eliza's Guts along with the skin so that Jack would come off as more of a Skelton with just this huge layer of latex like goo muscle.

Tbh, I'm really glad about how he comes out and really look forward to drawing him more in the future n_n
