Zap is a neon yellow living laser whose body is only of a face and a lightning bolt-shaped tail. He has lightning-shaped antennae, dark blue eyes with lightning-shaped pupils, a round brown nose, a wide mouth with sharp teeth and a green tongue, and two brown stripes on his back. He also has an electric aura surrounding him.
Powers and abilities
Zap can hover in place, and move side to side without moving forward, similar to a helicopter. Also, like an ordinary laser bolt, he can fly and bounce off surfaces, and is capable of destroying targets at incredibly high speed.
Experiment 603 was the 603rd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to be a living laser bolt. 603 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.
All of the experiment pods were released and scattered across the island of Kauai.
At an unknown point after this, Experiment 603 was activated.
In "627", 603 attacked a farmhouse, but was defeated when Stitch trapped him in a containment orb. However, Gantu and 627 arrived shortly after, and both easily managed to take 603 from an inattentive Stitch. 603, named Zap, was later seen multiple times flying around Gantu's ship.
The first 624 experiments, including Zap, were rounded up by Leroy and taken to a stadium to be destroyed. However, Lilo, Stitch, Jumba, Pleakley, Reuben and Gantu arrived before the experiments could be destroyed.
Zap participated in the following battle between the experiments and the Leroy clones.
The Leroys soon gained the upper hand in the battle but were defeated when Lilo, Stitch, Reuben, and several other experiments performed the song "Aloha ʻOe", which caused the Leroy army to shut down due to the original Leroy's fail-safe.
