- Species: Kangaroo (Macropus)
- Gender: Male
- Alignment: Evil
Ripper Roo (sometimes known as Dr. Roo) was the first of Cortex's mutations, and also his least successful one. Crazy, insane, not-all-there, Ripper Roo's behavior is as unpredictable as a blue kangaroo in a straitjacket can be. He is almost always heard laughing frantically.
His razor-sharp toe nails, combined with a tendency to jump around madly, make him a dangerous foe you wouldn't want to stand next to. After intense therapy, Ripper Roo became engrossed with books and science, revealing a sort of hidden genius. Unfortunately, he quickly reverts to his predominant, lunatic self, especially when he's caught in an explosion.
- Ripper Roo was intended to speak properly in Crash Team Racing, but the developers eventually decided to make him express himself through subtitled laughter (he does speak in the Japanese version, however). His English lines are actually still present in the game's data, despite being unused.

Crash Bandicoot 2 (first form)
Ripper Roo has grown blond hair (tucked inside his new top hat) and a mustache. He additionally has a pair of reading glasses, a bow tie, and a cane, which acts as a pogo stick.
He is notably more collected and shows signs of great intelligence, studying subjects like physics in his new library as a hobby. This all blows up quite literally with a well placed TNT explosion.
Crash Bandicoot 2 (second form)
When hurt by an explosion, Ripper Roo reverts to his usual, demented self, losing all additional props and revealing messy hair. His appearance is somewhat similar to Albert Einstein.
Crash Team Racing
Ripper Roo has gone back to his original design, minus the visible pupils. He is much more detailed, though he looks identical otherwise.
The blue roo's ears are now straightened, his eyebrows are jagged, and his fur is darker.His eyes are now constantly shrinking red circles instead of yellow swirls. The sleeves on his straitjacket are looser.
