Doctor Zeul

The contemporary version of the character is the alter-ego of Doris Zeul (1)who suffers from a fatal blood disease. She captures Wonder Woman and plans to put her "life-essence" into Wonder Woman's body using an experimental machine. Interrupted by Wonder Girl halfway through the experiment she ends up with her consciousness in a test animal gorilla named Giganta.(2)

Desperate to return her mind to a human body, Zeul the gorilla abducts a comatose circus strongwoman named Olga with size-changing abilities through unknown means (though Olga was comatose due to a mysterious shaman)(4) and uses the machine to successfully transfer her mind into that body, keeping the villain name "Giganta".

Giganta was created by William Moulton Marston and Harry G. Peter, first appearing in Wonder Woman #9 (1944).

Character Edits: Hello! A few citations for clarity.

1- Doctor Doris Zeul. I earned it. I will be addressed as it. Thank you.

2- The “test animal” was a Western Lowland named Molly and she was lovely. Nicer and better behaved than most humans, plus could reed together ladders.

3- I have not had sex with Grodd. Neither did Molly. Due to the transference, I share a bio-energy signature that simian males pick up on and become quite confused and aroused with. Gorilla City denizens consider me a “fetish” and it’s unflattering.

4- Olga was not “comatose due to a shaman”. She was a survivor of a circus train crash with no family to be found. Her muscles had atrophied due to the lack of movement and brain activity. It was also done by Dr Gerard Shugel, a pioneer in cerebral transference. Who happens to inhabit a white gorilla often. Yes I know. He also did my enhancement. And they’re fantastic. I have done the diligence in looking for the family. Anybody coming forward, you’ve had your chances. I know my rights.
