Dr. Nefarious Tropy (N. Tropy to friends) is an old ally of Uka Uka's. He is a master of time and quantum warp technology. He wears a device that gives him the ability to travel through time, but he is easily frustrated and has a very short temper, with every wasted moment feeling like an eternity to him. He usually carries around a giant tuning fork that he uses to fire energy beams and projectiles.
The blue doctor is the proud creator of the Time Twister, a station capable of warping anything through time. After he was defeated by Crash, the Time Twister couldn't hold itself together without his constant care and control, leading to its destruction.
One of N. Tropy's hobbies is disturbing the time flow by creating time paradoxes for laughs. He speaks in a distinct faux-British accent.
N. Tropy's name is a play on the word 'entropy', which is heavily associated with the second law of thermodynamics. In less specific contexts, it usually translates into a lack of order or predictability, something that the doctor tried to prevent with his Time Twister.

N. Tropy no longer has the large watch on his left wrist. His head is slimmer and his eyes have stretched out irises and green sclerae. His tuning fork is much wider and pointier, resembling a bident more than anything. The color of his armor is somewhat duller, and the little tuning fork on his helmet is now facing sideways.
Thanks to Crasharki for the picture.

N. Tropy has mostly reverted to his original design, except for the much brighter armor with chunkier shoulders. The pistons on his back appear bolted on the bottom.
N. Tropy went through a car wash and has come out much shinier and more polished than usual. He now wears leg armor and his left arm is either robotic or wrapped in a huge metal casing. There are 3 buttons visible on his lab coat instead of 2. N. Tropy now has 5 fingers on his right hand thanks to this becoming the norm for every character in the game, but his left arm still only has 4 (which suggests that it really is a robotic replacement). His eyes now have yellow sclerae.
