It's Hal Jordan during his 5 minutes as a Red Lantern. I tried for the whole "spewing blood" thing that accompanies being a RL, but I couldn't get it just right, so I said "the heck with it". Let me know what you think.
Note: As with my previous Hal cubee, the head art belongs to Adrian-Nation; it was borrowed, with permission, from Adrian-Nation's Robin III template found here [link]
Character is (c) DC Comics (as far as I'm aware).
