Nope, that's not Slade Wilson Jr., Kid Deathstroke, but rather Tino Mannary, pop star, super-genius, innovative inventor, racecar driver and business wunderkind! Yep, this guy was Kitty Pryde before Kitty Pryde was Kitty Pryde! All hail the sensational Marty Stu find of 1967: Tino Mannary!
Can't get enough fannery of that wonderful Tino Mannary? Check back later tonight, cats and kittens! (Also: humans.)
