Beast-Ruler src

The Beast-Ruler was an experiment by Doctor Thaddeus Sivana.

Sivana combined, in one humanoid body, the strength of a gorilla, the speed of a serpent, the fighting skill of a tiger, the cunning of a fox, the bravery of a lion, and the memory of an elephant, imbuing it with the Life Force drawn from a thousand beasts. The resulting creature was an uncontrollable enemy of all mankind, including Sivana. This monster took over Sivana's laboratory, then set free all of his test animals, and departed.

The Beast-Ruler undertook an anti-human rebellion, but was opposed by Captain Marvel, who punched him into a river, after which he was swept over a waterfall.


  • Language He was born with the ability to understand and speak English.
  • Memory He had the memory of an elephant.
  • Dominion Lions and serpents obeyed him.
