N. Tropy

Doctor Nefarious Tropy (voiced by Michael Ensign, Corey Burton, Masaru Ikeda, and Haruo Satō),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.

History
Warped/Wrath of Cortex

N. Tropy made his debut in Warped as the third boss in the game. Upon his defeat, the Time Twister Machine fell into disarray, trapping Cortex, Tropy, and Uka Uka in a time prison and morphing the first two into infants. N. Tropy plays a minor role in Crash Bandicoot: The Wrath of Cortex, in which he attends Uka Uka's bad guy convention. He acts as an obstacle throughout the levels in the game.

Crash Team Racing/Crash Nitro Kart

In the kart racing games Crash Team Racing and Crash Nitro Kart, N. Tropy is master of the relic races, and can be unlocked by beating all his ghosts in Time Trial mode in both CTR/CNK OR by holding the L1 + R1 buttons and pressing Down, Left, Right, Up, Down, Right, and Right in CTR.

Crash Twinsanity N. Tropy's latest appearance in the main series was in Crash Twinsanity as the fifth boss alongside Doctor Nitrus Brio when they, using the vast resources from Doctor N. Gin's company, hunted for treasure. They were easily thwarted by Spyro the Dragon. It seems now that N. Tropy is no longer working aside the likes of Cortex, working with N. Brio instead, but still on the same side as Uka Uka nevertheless.

Handheld Appearances

In Crash Bandicoot 2: N-Tranced, N. Tropy is entrusted by Uka Uka with the task of aiding him in universal domination. To do this, N. Tropy kidnaps Coco and Crunch, as well as Fake Crash, who he believes to be the real Crash. He then enlists N. Trance to hypnotise them into joining him. However, Crash manages to turn the bandicoots back to normal, before defeating N. Trance and N. Tropy. N. Tropy has a cameo appearance in Crash Boom Bang! in the "Silhouette Quiz" minigame.

Personality
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 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 to the hands of the bandicoot.

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.
