Personality: The self named Dru-Head-of-Many is difficult to provoke to anger, he doesn't even remember the last time he snapped. This particular Hydra Head is patient, though possesses a kind of... we'll call it "low cunning." He tries to act as arbiter between the other heads, but his own abilities cause as much, if not more chaos than a simple disagreement. Dismemberment is all well and good until everyone's on fire.
Dru-head has quite the repetiore of wisdoms and sayings he enjoys sharing, and the other heads don't exactly have much ability to shut him up. He thinks they like it when he does so. Typically they manifest as a poor rendition of half-heard human phrases. "You know what they say, Six heads are better than one, so... two birds in the hand..."
Dru-head-of-Many is as curious about his origins as anyone would be. He's spent his years and limited mental capacity in an attempt to better understand his nature... to limited success. He's certainly grown powerful, but even Dru-head knows how poor his chances are of gleaning any kind of information from academic studying would be. Where would he even go to school? He ain't got no hands. Instead he turns to the whispers of nature.
