Junjei

Junjei was with Shane's gang, in a battle against Dr. Black. They didn't have many slugs left, and some were tired, until they heard a motorcycle behind Shane's gang and Junjei. It was airborne above them, and someone was driving it, but their face was hidden by a helmet. They only saw the person fire their launcher, releasing a black and purple slug that had already transformed. It unleashed black fire that surrounded Dr. Black and his henchmen. It was a strange slug; it simply returned to the person, who only looked at Shane's gang before accelerating away.
