From superman.nu: Supermanica
Jolax and Mya
Aliens from the dimensional realm of Thraxx that arrive on earth to broadcast Superboy's exploits to their homeworld. Disguised as TV producers, Jolax and Mya arrange for Jonathan and Martha Kent to swallow a serum that makes them apppear youthful, but ironically this change is unpopular with the television viewers from the Thraxxian dimension (SB No. 145, Mar 1968: "The Fantastic Faces!").
