Gil A.K.A. "Gill"
Voiced by: Justin Berfield
Real name: Gil Moss. A former camper at Camp Wannaweep. When Ron attended Camp Wannaweep, he swapped Gill his afternoon swim, for arts and crafts. Gill tells us in the episode "Sink or Swim" that the lake where he swam so much was polluted, and caused him to mutate into a fish-type mutant. At the end of "Sink or Swim" Gill is taken away to be cured in a fish tank. The scene where he is pulled along the lake is featured in the Kim Possible title sequence. In a later episode "Return to Camp Wannaweep" Ron is thrust together with Gill once more, when Kim's cheerleading camp is re-located. Gill is an opposing mascot, and is cured of his mutation. Gil (his name is changed back as well) tries to befriend Ron, but Ron follows him around not trusting him, until he spoils the surprise of Gil's mascot costume. The camp turns against Ron, until one night, Ron once again follows Gill (changed back again) in his search for the last grotto of polluted water. Gill finds it, mutates, and Ron makes an amazing decision. Following in the footsteps of his second most hated foe, Monkey Fist, Ron jumps in too and mutates into a beaver. They end up fighting at the clown camp, Kim and Bonnie tie Gill up and he is sent away again.
