Kingdom Hearts Birth by Sleep
''Stitch! The Movie (2003)''

An alien created by Dr. Jumba through genetic experimentation.

His body stores an electric charge which he can use to shocking effect when threatened.

Usually, 221 stays in pod form, and only emerges when hydrated.

Kingdom Hearts Birth by Sleep
When Terra and Jumba reach the room that Experiment 626 is contained in aboard the massive, galactic ship, Jumba tells Terra that Experiment 626 is evil and design to destroy everything he encounters as he subsequently releases his experiment. Experiment 626 then lunges at Terra and steals his Wayfinder, though soon after drops it and leaves the room after Terra pleads with him. Terra then questions if Experiment 626 really is evil in nature. Having become livid at his experiment's evilness being questioned, Dr. Jumba assures Terra that he is incorrect by pulling out a small green ball and laughing hysterically as he drops it into a test tube of water. Experiment 221 emerges and attacks Terra. After a battle in the containment room, Terra defeats Experiment 221, who reverts back to its pod form.

Personality
Experiment 221 prefers to be left alone, and usual is prompted to use its electrical powers when provoked, also becoming quite angry. The experiment longs to be free, and is otherwise harmless. Unlike Experiment 626, who would seem to have goals and a demeanor independent from Dr. Jumba's intentional design, Experiment 221's only goal to carry out his primary function at his creator's command.

Appearance
Experiment 221 is a short, squat, yellow extraterrestrial, who has massive blue eyes that shine on his narrow, wide head. On both sides of his head is a small ear. Long, forked antennae protrude from the inner sides of the eyes, and large, flat teeth lie in its blue mouth beneath its domed, yellow nose. Experiment 221's belly is white and has a short tail sticking out behind it.

The name "Experiment 221" is derived from its creation, as it is Dr. Jumba's 221st experimental creature.

Fighting style
Experiment 221 is an agile fighter that uses speed and electrical attacks to deal massive damage. It can also manipulate objects, such as the blasters hanging from the ceiling, which it uses to fire a series of blasts at Terra.

Origin
Experiment 221 originates from the 2003 Disney film Stitch! The Movie, in which he is a central character. In the original movie's spin-off, Experiment 221 is the first of the Jumba's other 625 experiments to be activated from pod form. He is activated by Lilo and Stitch, the latter being Experiment 626 under a different name. However, Experiment 221 goes on a rampage throughout the town, shorting out all electrical appliances in sight. Soon after, Lilo and Stitch manage to catch him, and convince him to be good, instead of malicious. Experiment 221 is then left in the old Lighthouse, providing the electricity needed to turn on the light, giving him a purpose and pleasing the experiment.

Just like Stitch, Lilo gives Experiment 221 a name of his own: Sparky.
