So, in a discord server, the concept of a Human!AU for Lilo & Stitch came up. Where as others focused on the first film, I was more interested in returning to my childhood of the Lilo & Stitch tv series and their experiments.

The idea is that Jumba's experiments are able to pass as humans and not know they're experiments. Their genetic mutations only come out once they're exposed to an enzyme in pineapples. Yang here woke his powers up alongside Yin's when he was working as a server at a resort when he tripped, causing a pineapple-based drink to splash on the two of them.

With volcanic vents on his shoulders and wrists, Yang is able to fire lava from himself and couldn't control the spewing at first. Once calmed down by Lilo, Stitch, and Jumba, Yang now works making new islands with his partner Yin.
