Spirit is the Joe team's tracker, but don't assume it has anything to do with his ancestry.
As a child, Charlie Iron-Knife was diagnosed with sensory integration dysfunction, which caused him to overwhelmed with input in crowded situations: while most people are able to focus on only part of what's happening around them, such as one conversation or scent, Charlie couldn't shut the others out, so experienced them all equally. It got to be too much for him, and he took to going into the desert for solitude. One night, he noticed pawprints, and tracked the coyote that had made them.
- There have been no toys of this version of Spirit.
- Spirt's tracking abilities are due to his sensory integration disorder.
