Pandora

Pandora is a Devil Arm that Dante obtains in Devil May Cry 4. At rest it looks like a grey, cracked briefcase marked with a three-eyed skull, but it can transform into 666 different forms, some of them powered by a built-in Disaster Gauge; the player has access to seven of them, including Epidemic, a double-barreled bow-rocket launcher, Hatred, a triple-barreled shoulder rocket launcher, and Revenge, a laser cannon the size of Dante.
