Rocker was one of those guard dogs who should make sure that Kaibutsu didn't escape from a scientific institute. When Kaibutsu escapes anyway, Rocker followed his leader Jerome to do everything they could to stop him.

As they find the monster and stand together for the final fight, Rocker attacks Kaibutsu after his pack mate Robert. He runs like lightning and aims at Kaibutsu's main heart vain. He bits hard, but doesn't succeed in destroying the vain.

Kaibutsu closes his jaws around Rocker's head and crushes his skull. Rocker gets thrown dead to the ground.
