Thaddeus Sivana, Jr. src

Thaddeus Sivana, Jr. is the young son of Doctor Sivana and the youngest sibling of three.

A dead ringer for his father, Thaddeus Junior was a brilliant young man who freed the Monster Society to distract the Marvel Family while his father tried to organize Sivanaday. Junior helped his brother Magnificus try and stop Captain Marvel but was swatted away by Captain Marvel, Jr., who used a construction vehicle as a bat. Junior was hit so hard, he landed on the moon.



  • Power Loss: If Thaddeus Jr. is made to say the word "Sivana", he can lose his powers completely and be forced back to his human form.
