Here's a flashback for y'all... Graphic Mouse Amalgam D/O circa 2008! I was prescient enough to save my brief outlines at the time, so here's the setup for...
HEX-HULK The DC Universe's Old West Bounty Hunter get's himself irradiated with some doggawn Marvel Universe gamma particles and winds up bustin' out of his hat inta the Hex-Hulk. Yeehaw. The greenest - and meanest gun in the Old West. Plus, he's real ugly! I don't know that much about Jonah Hex - just what I saw in the Animated Batman episode 'Showdown' really. He did appear occasionally in the DC event comics - but to a very limited cameo-level degree as I recall. As for the Hulk? Well, you wouldn't like him when he's angry.
