Thaddeus Sivana Jr.

A scion of villainy in the grand DC tradition, Thaddeus Sivana Jr. made his entrance in the Bronze Age pages of World's Finest Comics #273 (1981), brought to life by Martin Pasko and Joe Staton. He's a character defined by extraordinary company — sharing the page with his infamous father Dr. Thaddeus Bodog Sivana, siblings Beautia, Magnificus, and Georgia, and even Green Lantern across his appearances in Shazam!: The World's Mightiest Mortal and beyond. Catalogued in Who's Who: The Definitive Directory of the DC Universe, he holds a modest but genuine place in DC's mythology, the kind of deep-cut family connection that rewards readers who love the rich, sprawling Sivana legacy.
