Well, haven't we gotten far for a pair of fuzzy marsupials. I am Doctor Nefarious Tropy, master of time and creator of the very Time Twister Machine you see before you. Uka Uka and Doctor Cortex have sent me to end this little charade, so you won't be leaving my area with the Crystals. I swear it!

Doctor Nefarious Tropy's intro speech, Crash Bandicoot: Warped / Crash Bandicoot N. Sane Trilogy

Dr. Nefarious Tropy (or N. Tropy for short) is the self-proclaimed master of time and specialist in quantum warp technology. He is an old friend of Uka Uka, called upon by the latter to help take over the world in Crash Bandicoot: Warped. It is stated in the Crash Bandicoot: The Wrath of Cortex manual that he can be seen disturbing the temporal flow by causing time paradoxes for laughs. He is shown to be a good friend of N. Trance.


Crash Bandicoot: Warped

Now you're on my time, you little skunk! Give me the crystals!

N. Tropy, Crash Bandicoot: Warped
Doctor Nefarious Tropy is introduced by Uka Uka in Crash Bandicoot: Warped as the creator of the Time Twister Machine, a device that will aid Dr. Cortex in his quest to gather the crystals in their original places in time. He later acts as the third boss of the game, battling Crash with his gigantic tuning fork. After being defeated, N. Tropy's suit seems to malfunction, as evidenced by his clock springing outwards, which sends him to the space/time vortex. Once he vanishes, Crash is granted the Death Tornado Spin. After defeating Cortex while in possession of all the crystals and gems, the ending will occur where is possible to see the two, who have transformed into infants, fighting over Uka Uka.

His boss battle style includes a wave of what appears to be electricity moving horizontally and vertically. Then, he switches up the platforms, which form a path to him. N. Tropy kneels down to rest and he is now exposed. When he is hit he uses his time warp/teleportation ability to warp other side of the room. If Crash is next to N. Tropy while he is still attacking or not kneeling down, N. Tropy will smash Crash with his tuning fork, vaporizing Crash across time and space. (He doesn't do this in the N. Sane Trilogy.)

Crash Team Racing

N. Tropy makes a return in Crash Team Racing, appearing as an unlockable character. To unlock him, the player must beat all eighteen of his records in Time Trial mode or use a cheat code. Tropy drives a sky-blue kart that. Like Tiny, Dingodile and Papu Papu, N. Tropy has high speed and average acceleration, but bad turning.

The epilogue of CTR states that he began tinkering with his time machine again and he was last seen entering a time portal.

Crash Bandicoot: The Wrath of Cortex

"There must be something we can come up with... say, Doctor, haven't you been 'tinkering' with some sort of new, secret weapon in your laboratory?"

N. Tropy has a minor appearance in Crash Bandicoot: The Wrath of Cortex, in which he is an attendee of Uka Uka's convention and an occasional enemy in the game, attempting to hinder Crash's progress in Atlasphere levels by shooting at him with his tuning fork, and later racing against him in a car. He also appears in the flying levels to battle Crash's glider and Coco's spaceship. He only has one line in the whole game.

Crash Twinsanity

The rats are leaving the sinking ship. Tell us where the treasure is and we'll... let you go.

N. Tropy, Twinsanity
In Crash Twinsanity, N. Tropy appears yet again. He is first seen after the Rusty Walrus chase in High Seas Hi-Jinks, with Cortex's old colleague, Doctor Nitrus Brio, who were seeking the Evil Twins' treasure. After not getting any information from Crash they decide to "wring it out of him". N. Tropy orders N. Brio to transform, and a boss battle ensues; the now frog-like Brio springs into the air and hits the iceberg's edge, sending Crash flying back to Cortex's Lab. N. Tropy reappears in the level Ant Agony, along with Nitrus Brio and N. Gin, to steal the Evil Twins' treasure, but was burned by Spyro the Dragon.


Crash Bandicoot 2: N-Tranced

N. Tropy is the main antagonist of Crash Bandicoot 2: N-Tranced, in which he teams up with his inter-dimensional crony, N. Trance, kidnaps Crunch, Coco and Fake Crash, and hypnotizes them into working for him. He is later defeated by Crash and is forced to take a group picture with the Bandicoots, much to his anger.

Crash Nitro Kart

N. Tropy is an unlockable character in Crash Nitro Kart, where he races under Team Cortex with Cortex, N. Gin, and Tiny Tiger. To unlock him, the player must defeat all of his ghosts in Time Trial mode.

Crash Bandicoot Purple: Ripto's Rampage

N. Tropy appears as a trading card in Crash Bandicoot Purple: Ripto's Rampage.

Crash Boom Bang!

N. Tropy makes a cameo appearance in the Silhouette Quiz mini-game.

Crash Bandicoot N. Sane Trilogy

N. Tropy reappeared in the N. Sane Trilogy serving the same roles as he did in Warped.

Crash Team Racing Nitro-Fueled

Baby tropy

Baby N. Tropy, as he appears in the N. Sane version of Warped and Crash Team Racing Nitro-Fueled.

N. Tropy reappears in Crash Team Racing Nitro-Fueled, once again as an unlockable character and is unlocked the same way as in Crash Team Racing. However, this time the player must beat all thirty-one of his records in Time Trial as opposed to eighteen in Crash Team Racing due to the inclusion of the Crash Nitro Kart tracks. Unlike in Crash Team Racing, N. Tropy cannot be unlocked via cheat code. His ending in Nitro-Fueled is identical to his original ending, except instead of going to a rainforest, he instead arrives in a futuristic city, only to head back after coming across a Marty McFly-like character.

N. Tropy's infant version, Baby N. Tropy, was added as a playable character in the post-Grand Prix update, and is available for purchase from the Pit Stop for 1500 Wumpa Coins.

Nefarious Tropy is a nefarious and smug character, as opposed to the childish, outspoken temperament of Doctor Cortex, with a smooth British accent to match. He proves highly intelligent, his technological breakthroughs arguably the most advanced of all of Uka Uka's scientists. However, he tends to get frustrated when he repeatedly misses his target, and as a result, tires easily. This usually works to Crash's advantage and results in Tropy's many defeats at the hands of the bandicoot. Like Cortex, he is also highly pompous and foul tempered, venting his frustrations at his associates or blaming them for his errors, something N. Trance was perfectly willing to call him out on.

Unlike most allies of Uka Uka, N. Tropy does not seem to be subordinate to Cortex, more of an equal and occasionally a rival for role as Uka Uka's right hand man. This can lead to conflicts between the two prideful doctors; it is Tropy that exposes Cortex's secret weapon in The Wrath of Cortex in suspicion he is holding out on ideas, while in Twinsanity, the two openly oppose each other for the Evil Twins' treasure, with Cortex ultimately mocking Tropy's comeuppance. Even as infants, they both fight for usage of Uka Uka with equal footing in Warped. He seems to have an affinity for time related puns, rarely letting a sentence go by without one. He also shows glaring traits of OCD (obsessive-compulsive disorder).


His outward appearance reflects an unhealthy obsession with time. Frequent travel through the cold and hostile vacuum of space and time has caused his skin to become light blue and extremely cold. He has long eyebrows and two equally long and skinny beards. His legs are long and skinny. His clothing has changed over the years, now seen as gold armor covering most of his body, except his waist. He also wears a golden-brown, smog-producing, piston-driven time machine, which appears to obscure his lab coat. He wears a tall headgear with a small silver fork. His left arm now has a huge metal glove with a clock on it. During his jumping animations in Crash Team Racing Nitro-Fueled, Tropy's hat briefly flies off, revealing him to be bald.


N. Tropy is voiced by Michael Ensign in all his speaking appearances, excluding Crash Bandicoot: The Wrath of Cortex, in which he is voiced by Corey Burton (who also voiced Doctor N. Gin in the same game). Corey Burton has reprised his role in the N. Sane Trilogy and Nitro-Fueled.

  • When N. Tropy makes his first appearance in Twinsanity, he and N. Brio try to force Crash to tell them where the Evil Twins' treasure is. However, the scene that explains this was cut.
    • N. Tropy hearing about the riches in the scene was supposed to be a joke where N. Tropy was watching the events of the game from the outside, but decided to join in when the treasure was mentioned. Ultimately his scene was cut since it would have been too expensive to create a high quality N. Tropy for that one shot[1] (as it was in an actual FMV). The scene was fully voice acted and was uploaded on Youtube in its storyboard form by a developer of the game on June 30th, 2018.
  • When he was turned into a baby at the end of Warped, he, like Cortex, still had his facial hair. This is likely due to oddities from the collapse of the Time Twister and not what he actually looked liked as a baby.
  • Although N. Tropy does not appear in Crash Bash, some music elements of his and Dr. N. Gin's boss theme from Crash Bandicoot: Warped are remixed for some minigames, most notably in Pogo-a-Gogo.
  • In Crash Team Racing, N. Tropy is one of the three characters who are never playable in adventure mode (and plays no part in the story line). The others are Fake Crash and Penta Penguin, who is unlockable via a cheat code. N. Tropy is also the only one of those three to appear in the credits.
  • In his Crash Bandicoot: Warped boss fight, if one looks closely at the clock that he turned on his hat, chest, and wrist, they all point at the same time of 10:10.
  • After beating his ghost in CTR, N. Tropy will say something different depending on the track. If the player beats all of his ghosts, he will congratulate the player and say that he's been unlocked as a racer.
  • When Crash fights Tropy in Twinsanity, the player can hear a clock ticking.
  • Even though N. Tropy doesn't appear in Crash Bandicoot Nitro Kart 3D, one of the cups is named after him.
  • N. Tropy was against N. Trance in Crash Nitro Kart, even though N. Trance served him in N-Tranced.
  • In Crash Twinsanity, the pistons on his armor do not pump and are still.
  • Even though N. Tropy has an Asian themed hub in Crash Bandicoot: Warped, there are no Asian-themed levels in his hub.
  • In Crash Team Racing and Crash Nitro Kart, his time trial ghosts never took shortcuts; in Crash Team Racing Nitro-Fueled, his ghosts now take some shortcuts.
  • His name is misspelled as "Trophy" in some games, such as in the credits of The Wrath of Cortex. This is lampshaded in the Crash Team Racing Nitro-Fueled Digital Comic, when Zem states that Nitros Oxide should be called "N. Trophy" after seeing his trophy collection.
  • A villain who debuted in Ratchet & Clank: Up Your Arsenal is named Dr. Nefarious, who in turn has an item named after him [Nefarious], the Dr. Nefarious Trophy, possibly hinting Naughty Dog and Insomniac Games' close relationship.
  • According to Uka Uka, in Crash Bandicoot: Warped, Tropy is his old friend. This could mean that Tropy is at least a few thousand years old. It is also possible that N. Tropy met Uka Uka in the past when he was experimenting with time.
  • Although he doesn't appear in-game, N. Tropy's tuning fork is used as one of Cortex's abilities in Skylanders: Imaginators. When placed, enemies around it will be slowed down; it can be upgraded to shoot sparks when Cortex fires his ray gun.
  • In Crash Team Racing Nitro-Fueled, N. Tropy's headgear can actually come off while jumping through the air. Underneath it, he is bald.
  • In Crash Team Racing Nitro-Fueled, N. Tropy's "Digital N. Tropy" skin, which can only be obtained by beating all of Nitros Oxide's time trial ghosts, features a digital clock set permanently at 12:30.
  • In the German version of Crash Team Racing, N. Tropy's name has been spelled as "N. Tropie". While the change in spelling works better as a pun on the German word "Entropie", it is inconsistent to the games that came before and after as those retained the English spelling even in the German versions.
