This was a quick practice with a tecnique I thought about for  Sparksairpirate request. It went a bit far and came out nicely. Ebony pencil on butcher paper.

Bomb Stripe was a police bomb squad expert. A chemical explosion, that should have killed him, spread cancer through those, ahem, certain glands located near his backside. After it was removed he discovered he had a form of psychokinesis in which the energy manifests itself almost like a phantom limb. The energy appears as a gaseous cloud. He has also developed a small amout of regenerative abilities.
Try not to punch too many holes in this story. :) This may just go into scraps later.
