Sor-Elbow is Gonzo's father, as seen in Baby Gonzo's Superman-inspired account of his origins from the Muppet Babies episode "Fozzie's Family Tree". Gonzo describes Sor-Elbow (after Superman's father Jor-El) as a brilliant scientist, and the planet Crouton's weirdest resident. He arrives home one day to inform this wife Weirda that their planet is in the process of becoming normal. Sor-Elbow's attire consists of a blue tunic with an S on his chest, no pants, and simple sandals.
