Rex Smythe-Higgins is a fictional character in the Hey Arnold! TV Series.


Rex is Grandpa's arch-rival, ever since he won the Tour de Pond 70 years ago when Grandpa's boat "mysteriously" got a number of holes in it; today, he owns the pond. He has a grandson that was also named after him, Rex Smythe-Higgins III.
