Thraxx
From superman.nu: Supermanica
Thraxx
A planet from another dimension that televises scenes from Superboy's life for the entertainment of its citizens. Because some Thraxxians believe Superboy's adoptive parents appear too old, Jolax and Mya of Thraxx change the real-life Jonathan and Martha Kent to a more youthful age using a rejuvenation serum (SB No. 145, Mar 1968: "The Fantastic Faces!").
