Horror

What the hell is that thing? That Sir is Horror! A living, breathing, radiated portal. When Horror is running low on ammunition or feeling threatened it will vomit a beam or irradiated matter that that melts its way through any target!!

Horror is one of the many playable characters in the Rogue like Arcade shooter Nuclear Throne, http://nuclearthrone.com

Yeah... Might be a good idea not to touch that thing...
