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. He is shown to be a good friends with N. Trance.

Crash Bandicoot 3: Warped
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.

Crash Twinsanity
N.Tropy gets mad at Cortex and decides to start his own alliance.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.

"Time for action!"

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

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 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. His clothing has changed over the years, now seen as gold armor covering most of his body, except his waist 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).
