Watching the video, it looks like his battery exploded. Stuff like that is not uncommon. But as big as eCig batteries can get, plus that fact that he had it right up to his face when it happened, it's a bit more dangerous than having a AAA battery or phone battery blow. I hope the guy makes a full recovery. :/

It's hard to pick a "most loved", but one that sticks out in my mind is Raoh from Legends of the Dark King. His one-track mind in the source of all kinds of badassery. Thoroughly enjoyable. Izaya Orihara from Durarara!! also sticks out in my mind. He's extremely clever and twisted, so it's fun to watch his plots unfold.
