Zap the Arm

Zap is the arm appearing in "Freak City." He is one of the body parts that make up Super Freak. He is an arm in freak form, so he is naturally Super Freak's arm. Like the other members of Super Freak (except Finn and Jake), he ultimately decides to stay together instead of returning to his old life because he is more powerful as part of the group.

Appearance
Zap is a humanoid. He resembles fire, as his entire body is a light red except his face which is tan yellow. He has "fiery" hair.

In "Freak" form, he looks just like Kim's "Freak" form, except Zap is taller and red. (Kim is also a leg, but based purely on looks, the difference is small).

Quotes
"Eh... It's a living."

"We're not afraid!"

"Yeah, we're strong together."

Trivia

 * Given his fiery appearance, Zap was most likely an inhabitant of the Fire Kingdom.
