Shredder

Shredder, A.K.A. Experiment 134, is an illegal genetic experiment created by Jumba Jookiba. He is designed to shred important documents. His one true place is with Mrs. Hasagawa as one of her "cats." Shredder is voiced by Frank Welker.

Bio
Experiment 134 was the 134th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to shred important documents.

134 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. Against statistically unlikely (but not impossible) odds, several experiment pods landed in one location: Mrs. Hasagawa's yard, 134's pod being one of them.

Lilo & Stitch: The Series
134's pod was found by Mrs. Hasagawa, who, mistaking it for an apricot, placed it in a colander for later consumption with several other pods.

After Lilo and Stitch redecorated Mrs. Hasagawa's yard without her permission, she was less than thrilled with the results, but decided to thank them for their work with the "apricots." The pods were then revealed, but before Lilo and Stitch could stop her, she washed them with a watering can, thus activating the experiments.

After his activation, 134 began to follow his primary function by shredding Mrs. Hasagawa's important mail. Lilo and Stitch believed the experiments to be a danger to Mrs. Hasagawa and along with Jumba and Pleakley, tried to catch them all. 134 was then captured in a container by unknown means.

134 and the other experiments were about to be taken away, but were returned to Mrs. Hasagawa when Lilo and Stitch saw how much she cared for them. 134 was then named Shredder.

Leroy & Stitch
The first 624 experiments, including Shredder, 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.

Shredder 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 `Oe, which caused the Leroy army to shut down due to the original Leroy's failsafe.
