Doctor Crocktopus (Doc Croc for short) is the alter-ego of Mr. Crocker when Timmy wishes that every ones has super powers. His affiliations are The Baby Shredder, Nega Chin and Bull-E. His powers are "giving four F's at the same time" with his tentacles, produce fire in the shape of an F, shoot a light blue energy wave with red F's and can seal people or other things in bubbles made of anti magic energy that are impervious to nearly anything.
His costume is a parody of another Marvel Comics character, Dr. Strange. Yet, his villainous roles is similar to another Marvel villain from Dr. Strange series, Baron Mordo, making Doc Croc is also Mordo's parody. While his most of his powers besides having a similar power as Doc Ock, are similar those of Dr. Strange's sorcerers' powers, such as a magic blast that can only gives F-signs, and flight.
Only 3 of his tentacles are mechanical as he mentioned that one of those wasn't mechanical.
