Grubba

Grubba was a Scrafty who managed the Glitz Pit. After the GTS became the champions, they discovered that he was actually slowly draining the other fighters of their life force and draining that of those who discovered what he was doing entirely in order to achieve immortality. The GTS stopped him by destroying his machine and causing the Gold Star to suck away all the life force he stole and turn him to dust, then return it to those who were still alive.
