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 stated in the wrath of cortex manuel that he can be seen causing time paradoxes for laughs. He is shown to be a good friends with N. Trance.

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, Crash earns the Death Tornado. 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.

"My time is up. But yours soon will be too."

Crash Team Racing
After they are saved by N.Gin, N. Tropy returns in Crash Team Racing, appearing as an unlockable character. To unlock him, beat all records in time trial mode or via cheat code.

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 by shooting at him with his tuning fork, and racing against him in a red car

"There must be something we can do, say doctor haven't you been tinkering with some top secret weapon in your laboratory?"

Crash Twinsanity
N.Tropy gets mad at Cortex and decides to start his own alliance with N. gin, N. Brio, and Dingodile. 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. If the player loses his boss battle, N. Tropy begins to dance, whirling his hand in front of his tuning fork as if it was a guitar. He is the only one who never joined Cortex again.

"The rats are leaving the sinking ship"

Crash Bandicoot 2: N-Tranced
N.Tropy is the main antagonist of Crash Bandicoot 2: N-Tranced, in which he teams up with N. Trance and 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
N.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."Time for action!"

The epliouge, of CTR, which most likely happened after all this, states that he began tinkering with his time machine again and he was last seen entering a time portal.

Personality
Nefarious Tropy is, needless to say, a nefarious and smug character as opposed to the bad 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 an asian-esque appearance (this might be why he has an Asian themed Warp Room Chamber in Warped). He wears a fork (similar to the one he carries) on his head and a small clock on his chest. Lastly, 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 golden-brown, smog-producing, piston-uely Asiandriven time machine, which appears to obscure his lab coat. He wears a tall hat with a small silv and his right arm. His left arm now has a huge metal glove with a clock on it.

Origin
The creators of Crash Bandicoot 3: Warped have stated that because the plot of Warped involved time travel, a time traveling 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!".

Portrayals
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).
