Lavasteel of Mount Lava
Lavasteel has the colors of steel and lava. She likes to eat lava and metal.
Her original programming by Jumba Jookiba was to eat everything metal and spit out huge lavaballs. Lilo and Stitch caught her and changed her. Her one true place is at the junk yard. She'll eat some cars and burn others. It keeps the waste down to go green.
