Fan Casting Dr. Thaddeus Sivana in Shazam! Champion of the Gods (1998)

Dr. Thaddeus Bodog Sivana is the main antagonist of Shazam! Champion of the Gods. A vengeful, genius-level scientist, characterized by his tragic upbringing, which turned him into a cold, arrogant, and sadistic individual driven by a desperate need for power and validation. As a child, he was summoned by the Wizard Shazam to the Rock of Eternity as a potential champion but was rejected for not being "pure of heart" after falling for the temptation of the Seven Deadly Sins. As a result of this, his primary goals as an adult are to ultimately harness the powers of Shazam in order to take revenge on the Wizard and all those who treated him with disdain for most of his life and to conquer the world, and he aligns himself with Mister Mind to do so.
