Deathstroke the Terminator is an anti hero you can't ignore. He is also known as Slade in Teen Titans.
As a scientist, an accident in the lab exposes him to magnetic particles, that alter his body - giving him magnetic powers. His wife makes a special suit to contain these powers and keep metal from being drawn to him while in public.
I used grey guidelines to draw this mid shot of Deathstroke. Half his face is in darkness. His muscles bulge beneath his armour. I sketched in the main lines with a black pencil. Then colored it with fills using the paint bucket by moving the opacity slider to 70%
Over this I airbrushed the darker shades and finally pencilled in the scales of the armoured suit.
