Welcome to Bandipedia!

You are crazier than me! Best get head checked if you think you could beat Oxide! Have a key. Good luck, you'll need it.

Ripper Roo (also known as Doctor Roo) is an insane blue mutated kangaroo. He is widely considered to be Dr. Cortex's first and failed experiment with the Evolvo-Ray, which is debatable seeing as how he managed to complete university-level education as of Crash Bandicoot 2: Cortex Strikes Back. He frequently uses explosive crates when battling Crash. This can be seen in Crash Bandicoot 2: Cortex Strikes Back, where he lays down TNT and nitro tiles with his cane, in Crash Team Racing where he drops TNT Crates, and in his appearance in Crash Bash where he will randomly lay down TNT tiles. He also has razor sharp claws on his toes that are his main method of attack.


Crash Bandicoot

In the original Crash Bandicoot game, Ripper Roo was one of the many animal test subjects of Dr. Neo Cortex. After being captured, he was zapped at least twice by Cortex's Evolvo-Ray which caused his fur to turn blue and for him to go insane. He was quickly straight-jacketed and abandoned, and came to reside in some ruins on Wumpa Island.

During the events of the game, Crash stumbles upon Ripper Roo on his journey on the way to Cortex Castle. Ripper Roo tries to attack Crash, only for Crash to defeat him with the use of Big TNT crates floating by. He is last seen passed out on the ground.

In the alternate ending to the original game, it's revealed that after Cortex disappears, Ripper Roo undergoes intense therapy and eight years of higher education, after which he writes a well-received book: Through the Eyes of the Vortex: A Study of Rapid Evolution and Its Consequences. This is the reason for "Doctor" Roo's change in character between the first and second game.

In Cortex Strikes Back, Ripper Roo reappears as the first boss in this game. This time, he's working for N. Brio, and is known as "Doctor Roo" because of his newly obtained doctorate in psychology. He had renovated his ruins home into a library, installing bookshelves along the walls, a desk by the waterfall, and replacing the 9 stone platforms over the water with one large one with his face engraved on it.

Once again, Crash intrudes on Ripper Roo, interrupting him in the middle of his studies. Ripper Roo tries to attack Crash, this time by placing TNT and Nitro tiles on the ground. Crash tricks Ripper Roo into blowing himself up with the TNT squares, which is enough to transform him back into his old insane self. When Ripper Roo is tricked into blowing himself up once again, Crash can swoop in to deliver the final blow. After the fight, Ripper Roo collapses onto the ground and is never seen again in the game.

Crash Bandicoot: Dansu! De Jump! Na Daibouken

Ripper Roo appears in Dansu! De Jump! Volume 1, where he is a doctor who spends his time researching. Instead of Crash and Aku Aku calling him 'Ripper Roo' they just call him 'Ripper'. His design is based on his Cortex Strikes Back look and wears a long sleeved shirt instead of a straight jacket. He speaks perfect English and acts as a normal citizen with no indications of Dr. Cortex or Brio creating him. In chapter 5, Furious Ripper!, Crash and Aku Aku arrive at his house on the hunt for food. When Ripper Roo finds out that they have a power stone, he becomes obsessed with snatching it from them and asks them to do some chores in return for some food and shelter. Unfortunately, Crash flattens his books and destroys his research. Ripper goes crazy with anger, attacking Aku Aku and bouncing around on his cane demanding them to hand over the Power Stone. After a brief battle with Crash, a chandelier drops onto Ripper's head, knocking him out. He soon turned back to normal and decides to make them some food. As it turns out, Ripper Roo's favourite food is a mixture of mouldy cake, rotten chicken and fish bones, which makes Crash and Aku Aku run away in disgust.

Crash Team Racing

Ripper Roo made another appearance in Crash Team Racing as the first boss and an unlockable character. His home track is Roo's Tubes. When racing him, he is constantly drops TNT crates onto the track. After defeating him, he gives you the first of four keys needed to race Oxide. The key given by him leads to Gem Stone Valley and The Lost Ruins.

Ripper Roo's kart in the game was orange. He can be unlocked by completing the Red Gem Cup in adventure mode. He can also be unlocked by holding L1 and L1 while pressing Right, Circle, Circle, Down, Up, Down and Right on the main menu.

After the events of CTR, Ripper Roo ran a successful campaign for state governor with the slogan "Crazy is as Crazy Does!". There were rumors of a subsequent run for president.

Crash Bash

In this game, he made a cameo appearance in the third Pogo Pandemonium stage El Pogo Loco in his Doctor Roo look, but he's still his regular crazy self personality-wise. He creates TNT, Nitro and 4-way tiles by hopping around on his cane. He will occasionally fire off a series of rockets in all directions as well.

Crash Twinsanity

Ripper Roo didn't return until Crash Twinsanity, where he made a brief cameo at Crash's "Birthday Party". After Cortex and the Mecha Bandicoot are defeated, he agrees to go out to lunch with Dingodile. He is silent in this game, like most of the other party guests.

Crash Nitro Kart 2

Ripper Roo reappears as a major villain and unlockable character in CNK2. In this game, he and Cortex agree to assist Nitros Oxide in his plan to turn the world into a parking lot. He is unlocked by completing missions 3 and 4 in mission mode. In this game he wears a white t-shirt as opposed to his usual strait jacket, with his hands and arms being clearly visible when turning.

Crash Bandicoot Nitro Kart 3D

Ripper Roo appeared in CBNK3D as a playable character who teams up with Cortex and Nitros Oxide. He has a different look: he takes after the classic stereotype of the boxing kangaroo, with boxing gloves instead of his trademark straitjacket, and a more realistic kangaroo head shape. He is also revealed to lack a pouch, much like actual male kangaroos.

Crash Bandicoot Nitro Kart 2

Ripper Roo appeared again in CBNK2 as an unlockable character. He went back to his CTR look, but wears his Dr. Roo top hat. He does his trademark laugh when he hits another racer with a weapon. He is unlocked by getting 62 mission points. His kart is unlocked by getting 67 points.

Crash Bandicoot N. Sane Trilogy

Ripper Roo reprises his role as a boss in the first two games in the N. Sane Trilogy. He has a new animation for each of his defeats. In Crash Bandicoot, he'll stumble and fall off the edge of the waterfall. In Cortex Strikes Back, his head gets stuck in the ground. He pulls it out, leaving his wig behind in the ground.

Crash Team Racing Nitro-Fueled

Ripper Roo reprises his role as the game's first boss. Like all other CTR bosses, he is instead unlocked by defeating him in Adventure Mode. His epilogue was completely changed: after the events of the game, Ripper Roo becomes a thrill ride engineer. Once it was revealed that he simply used each ride to check his limits in enduring pain, he was blacklisted by all amusement park owners.

Crash Bandicoot 4: It's About Time

Ripper Roo is seen hopping around the rooftops in the level "Off Beat". He is later seen in the 100% ending, having captured N. Brio in his pterodactyl form as a taxidermy exhibit at "Ripper Roo's Curious Cabinet of Curiosities".

Crash Bandicoot: On the Run!

While Ripper Roo himself doesn't physically appear in On the Run!, a Ripper Roo themed skin for Crash was added in season 2, Running Outta Time.



Ripper Roo is famous for his insane, psychopathic, and somewhat dangerous behavior. As a result of his insanity, he can be fearless, reckless, impulsive and unpredictable, often blowing himself or others up repeatedly with explosives. He has also proven to be highly tolerant and resilient to pain, as demonstrated in his boss battles when he gets caught in a TNT or Nitro blast, either getting knocked out cold, becoming dizzy or just laughing it off. His resilience and thrill-seeking nature is further developed in the epilogue of Crash Team Racing Nitro-Fueled where he becomes a thrill ride engineer, only to get blacklisted due to his intentions in creating said rides (only to test the limits of his pain threshold). Yet despite his presence as a psychotic lab animal antagonist, he’s also shown to be rather playful and fun-loving when not being forced to face against Crash, relishing in excitement as seen in his CTR Nitro Fueled animations (sticking his face out in a driving animation similar to a dog in a car, in an extended jump where he claps his feet together, celebratory fist pumping with his footpaw when he wins a race, etc.) and as shown in the Crash Bandicoot 4 level “Off Beat”, he is seen in the background happily hopping around the rooftops enjoying the festivities. This is also enforced in his Crash 4 concept art where he is depicted balancing on a giant bowling bomb and playing with a pogo stick composed of TNT.

Ripper Roo seems to have two sides to him - the other being Doctor Roo, seen primarily in Cortex Strikes Back. Prior to the game, he spent a year studying to become a psychologist, and penned a well-received book titled "Through the Eye of the Vortex: A Study of Rapid Evolution and its Consequences". He seems to spend his free time studying, and shows irritation at his studies being interrupted. However, an explosion is enough to return him to his usual self.

He is unique as the only speech he is capable of is insane laughter. In CTR, luckily for the player, subtitles are used while he is "speaking". In the Japanese version of the game, however, he spoke coherently. Oddly enough Ripper Roo seems to have some attachment to water as his boss fights always take near water and Roo's Tubes, his track in CTR, is an underwater facility.

Physical Appearance

Ripper Roo is a boomer (male kangaroo) with royal blue fur that covers most of his body, sky blue for his face and belly, and navy eyebrows and a black nose, although it's dark pink in Crash Twinsanity. He has long floppy ears (straightened in Twinsanity) with sky blue insides, except for in Twinsanity, where they are pink. His eyes have yellow scleras with orange circles swirling around his pupils. In Twinsanity, his scleras are white, and he has no pupils, only red circles. He has sharp teeth, black claws on his toes and a long pink tongue. In Crash 1 he had darker blue fur on his toes, but this was removed in all subsequent appearances. He wears a white straitjacket that is completely buckled around his arms, limiting movement. The length of his tongue varies depending on the game, ranging from a very long one in the Naughty Dog games to a more realistic length in Twinsanity.

In his Dr. Roo getup, he retains generally the same appearance, but gains some new accessories. He wears a black top hat, glasses, a blonde wig and moustache, and a bow tie. The bow tie is red in Crash 2 and Crash Bash, but was changed to purple as of the N. Sane trilogy. He is also seen with a cane in this form.


Crash Bandicoot

  • Manual

“Crazy, demented, not-all-there. These are kind words to describe an animal who has undergone one (or two) zaps of the old Evolvo-Ray too many. Not much of a conversationalist either, we hear. Do your best to avoid contact with Ripper Roo and his razor-sharp toe nails.”

Crash Bandicoot 2: Cortex Strikes Back

  • Manual

“Ripper Roo is back, madder than ever. He’s had time to perfect his attack so make sure you don’t try to stand toe to toe with this one.”

Crash Nitro Kart 2

  • In-Game

“A crazy racer with bursts of acceleration, but speed isn't his strong point.”



Nitrus Brio

Ripper Roo and N. Brio are apparently on good terms, working together during Cortex Strikes Back. Brio had a hand in Ripper's creation as Cortex's former right-hand man, though Ripper doesn't seem to hold a grudge against him, making him Brio’s most loyal minion. Their relationship takes a different turn in It’s About Time, where Ripper Roo captures N. Brio in his pterodactyl form and displays him as taxidermy in his museum, “Ripper Roo’s Curious Cabinet of Curiosities”.

Neo Cortex

Cortex is Ripper Roo's creator, though he quickly escaped him and went to reside in the ruins over a waterfall on Wumpa Island. Ripper Roo hasn't been shown to hold a grudge against Cortex for this, though he never worked with him after that, siding with Brio instead in Cortex Strikes Back.

Crash Bandicoot

Crash and Ripper Roo have always been on opposite sides of the games' conflict. Ripper Roo attacked and tried to kill Crash multiple times through his boss fights, and he shows irritation at Crash arriving whilst he was studying during Cortex Strikes Back.


In Twinsanity, Ripper Roo and Dingodile are friends, or at least on good terms. After the Mecha-Bandicoot boss fight, Dingodile asks Ripper Roo to hang out with him for lunch, and Ripper Roo enthusiastically accepts the offer. However, they have not been seen interacting with one another in any other game they both appear in.
