Two red shirts from Project Dark Star, both merely plot devices. John was incapactiated on the titular meteor and imprsonated by Tharuk, who used his best friend Butterscotch to get a new clawshot after the old one was trashed. Butterscotch was later killed in Vocal Volcano by Tharuk after Tharuk was done with him.
John (full name John Jangle Jingleheimerschmitt) had his full tale written about in Xar Gaiden. He was healed by the Doctor, and set off to catch up to the other Kirby clones, to no avail. He wound up in control of the demon beast chimera Popwrath, tried to hunt down Tharuk, failed, and was stranded in the Mirror World.
