Wizzo

From AmtWiki

This guy who was placed inside a plastic garbage can (of the 39 gallon variety) that was also filled with Fireballs and had Harden cast on it. People wheeled him around Clan and he'd pop up and chuck fireballs then duck inside again.

Eventually the other team killed his porters then wheeled him in circles at high speed and pounded on the can until he gave himself up.
