Experiment 221 appears in the prequel game to the Kingdom Hearts series in Deep Space, Stitch's homeworld in this incarnation. During this time, Sparky was still in his pod form under Jumba's watch, while the rest of the experiments were presumably also in pod form. However, Jumba took Sparky's pod with him when he was arrested and brought it onto the Galactic Federation's ship when Experiment 626 (Stitch) was discovered and captured. After feeling insulted by Terra when the latter believes there was good within 626, Jumba decides to demonstrate to Terra the evilness within his experiment by activating Experiment 221's pod, causing Experiment 221 to emerge and attack Terra. When Terra defeats Experiment 221, it reverts to its pod form, though Jumba then tries to console it by saying everything will be all right.
