N. Tropy

Doctor Nefarious Tropy (or N. Tropy for short) is the self-proclaimed master of time and quantum warp technology. He is an acquaintance of Uka Uka, called upon the latter to help take over the world in Crash Bandicoot 3: Warped. It is commonly stated that he can be seen causing time paradoxes for laughs.

Crash Bandicoot 3: Warped
"Now you're on my time, you little skunk! Give me the crystals!" Doctor Nefarious Tropy is introduced by Uka Uka in Crash Bandicoot 3: Warped as the creator of the Time-Twisting Machine, a device that will aid Neo 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 defeating him, you earn the super spin move. After the time twister machine is destroyed by Crash, N. Tropy, Cortex, and Uka Uka are trapped in a time prison and are turned into infants.

Crash Bandicoot: The Wrath of Cortex
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.

Crash Twinsanity
Tropy appears again in Crash Twinsanity, where he works with Doctor Nitrus Brio in order to learn the whereabouts of the treasure of the Evil Twins. When interrogating Crash proves fruitless, the duo attack him, sending him back to Cortex's Iceberg Lab. They eventually reach the treasure trove of the Evil Twins, but are chased out by Spyro the Dragon.

Crash Team Racing
Tropy appears in Crash Team Racing as the player's opponent during the Time Trial races and later as an unlockable playable character. The game's epilogue states that Tropy resumed his time machine hobby after the events of the game, and was last seen entering an ancient rainforest.

Crash Bandicoot 2: N-Tranced
Tropy is the main antagonist of Crash Bandicoot 2: N-Tranced, in which he 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.

Crash Nitro Kart
Tropy is an unlockable character in Crash Nitro Kart, where he races under Neo Cortex's team. His face is shaped like an hourglass here. To unlock him, defeat all of his ghosts in Time Trial mode.

Crash Boom Bang!
N. Tropy has a cameo appearance in Crash Boom Bang! in the "Silhouette Quiz" minigame.

Personality
Nefarious Tropy is, needless to say, a nefarious and smug character as opposed to the short temper of Doctor Cortex, with a smooth British accent to match. He appears to be the smartest out of all the doctors, but 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 to the hands of the bandicoot.

Outward appearance
N. Tropy's 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, giving him a vaguely Asian appearance. He wears a golden-brown, smog-producing, piston-driven time machine, which appears to obscure his lab coat. He wears a tall hat with a small silver fork (similar to the one he carries) on top and a small clock on the front. Lastly, his legs are long and skinny.

Origin
The creators of Crash Bandicoot 3: Warped have stated that because the plot of Warped involved time travel, a time travelling boss was called for. This led to Nefarious Tropy's initial creation. Tropy's shortened name is a pun on the term "Entropy", a measurement of chaos, randomness, and disorder.

Errors and glitches about his boss fight in Warped
When defeated, N. Tropy has a quote to say just like his villainous fellows N. Gin and Dingodile do, but if the player stands too close to Tropy after having finished him off, Crash will be instantly warped to the Warp Room.

Instead, if the player uses a slide, a then-powered-up double jump and finally a Tornado Spin in order to glide towards the other main platform, he will hear N. Tropy saying "My time is up. But yours soon will be too!". Of course, with N. Tropy's time travel stick, one can simply pretend it's a temporal echo. So it's all good. During the second time onwards you can also do another glitch involving using the slide, double jump, and tornado spin to glide towards the platform where Nefarious is standing, but gliding into the little chinese house instead. As long as you do not jump up while Nefarious is trying to hit you, you will not get blasted to bits. Makes for a awesome screenshot of Nefarious Tropy in action.

A glitch randomly may occur during this boss fight, if played from the second time onwards: if the final hit is delivered through the glide described above, the game sometime freezes, with the frame showing Crash spinning and Tropy still having his head lowered: the sound effects aren't heard anymore while the BGM goes on playing. This hasn't been corrected in the game's PSN release, available for download for PSP or PS3.

Portrayals
