Bio: The character of Man-Cat used to be known as the hero Cat-Man of Holyoke publications. The character had long since fallen into the public domain when Alex Ross and co-scripters of the Project Superpowers series and it's spin-offs chose to revive the character as Man-Cat.
In the series, a number of public domain heroes were trapped in a magical urn and stayed there for over half a century before being released by the man who put them there, The Fighting Yank. Some heroes came out of the urn transformed, as is the case with Man-Cat. Where as he used to be a man simply raised in the jungle by tigers, he now seems to actually be part tiger. He's feral and vicious and his main instinct seems to be the want to hunt.
Notes: Please note, the renaming of Cat-Man into Man-Cat was never specifically addressed on page (the character is not the only character in the Project Superpowers series to have simply been renamed to something similar to the name they used to possess). The characters in the series simply referred to him as Man-Cat. The renaming of the character took place in the sketchbook section of Project Superpowers: Chapter Two Prelude (2008) One-Shot where an Alex Ross sketch of the character was accompanied by the new name. The character did briely appear in Volume One of Project Superpowers in issue #0 in a flashback scene. Since this appearance is a flashback and took place before the Chapter Two Prelude, the character appearance in that book remains Man-Cat. All appearances after the Chapter Two Prelude however, are as Man-Cat.
