Charlie is the second head protruding out of Scrad's body. Charlie is just a long neck with a small head identical to Scrad's. Charlie is actually inside Scrad's backpack, so no other humans see him. Despite Scrad being a moron, Charlie appears to be even dumber, implying they have two separate brains and personalities. Charlie tends to make jokes even during serious situations. Scrad and Charlie help Serleena in her search for the Light of Zartha.
- It is hypothesized that Charlie is a Symbiote, a strange being introduced in the animated series that attaches to a host and serves as a second head.
