Yang (Experiment 502) is a red, male, half-dog half-lizard weasel/dragon-like experiment with four volcano-like pits along his back and two on his head. At his natural four leg stance he is shorter than most other experiments, but when rearing on his hind legs, he gains at least a foot of height over them.
He is able to shoot magma from the pits along its back, in a similar manner to the nasal opening on experiment 619's face, shoots fireballs from his back and heats ground with his feet. It was thought that when he came in contact with Yin, the combination of their abilities would create a massive explosion. However, instead they learned that water and magma was actually a good combination.
He is also able to project heat into the ground with his feet and create a red glowing effect with his eyes.
- Plugging the vents on his back with a sticky substance, as well as his feet.
- Possibly water as well

One True Place
Creating new islands with 501 around the island's border.
- He is the twin on Yin, being her opposite
- He is seen in a later episode playing cards with several other experiments.
- After being freed in Leroy and Stitch, he works with Yin to seal several Leroy clones in solid magma.
- Yang (known by his number 502 at the time) was activated at the same time as 501, when Lilo and Stitch were arguing.
