Warhammer FanLore X Asura's Wrath.

The Angry Marines get so PISSED OFF that their collective rage causes Asura to get dragged out of his peaceful afterlife in Naraka, raked through the Immaterium, and spat out in The Warp as the newest Chaos God! Only, he wants to go back home because his wife will probably kill him for running out on her. And that pisses him off so much that his anger flows down the line to the Angry Marines making them even more pissed off, which increases Asura's level of pissed off, ad nauseum until a singularity occurs and the entire galaxy ragequits.
