Fang's pet dragon, the last host he fled to, killed by the EMP pulse before he could finish taking her over.
Mordecai explains that after escaping Donut's War Crime spell as a speck of machinery, Fang could not sustain himself for long and went straight to the only other member of his team he had left: his pet dragon.
He installed himself into her and was probably in the process of taking her over — or waiting for another body to be printed — when Carl's No Disassemble EMP Bomb pulse killed the dragon and splattered him with her.
A dragon large enough to be a warlord's pet and mount, downed by an electromagnetic pulse.
Fang's last refuge, destroyed along with him by the EMP bomb.
