Zap, A.K.A. Experiment 603, is an illegal genetic experiment created by Jumba Jookiba and a character in the Lilo & Stitch franchise. He is designed to be a living laser bolt. He was captured by Gantu, but was rescued in "Snafu". His one true place is at a power plant. He is voiced by Frank Welker.
Zap is a bright yellow, living laser beam and has lightning-shaped antennae, dark blue eyes with lightning-shaped pupils, round brown nose, a wide mouth with sharp teeth and green tongue, two brown stripes on his back and a small earless limbless dog-like body.
Zap can hover in place, and move side to side without moving forward, similar to a helicopter. Like an ordinary laser bolt, Zap can fly and bounce off surfaces. He is capable of destroying targets at incredibly high speed.
- Zap's pod color is yellow.
- Zap is one of the few experiments to not appear in the group photo at the end of Leroy & Stitch.
