N.Trophy

Dr. Nefarious Tropy (or simply known as N. Tropy) is a major tritagonist in the Crash Bandicoot video game series, appearing as a major antagonist in Crash Bandicoot: Warped and as the central minor tritagonist of Crash Bandicoot 4: It's About Time. In the alternate timeline, he appears as a minor antagonist in Crash Bandicoot: The Wrath of Cortex and Crash Twinsanity.

N. Tropy returns as the secondary antagonist for Crash Bandicoot 4 which takes place directly after the events of Crash Bandicoot 3: Warped. Trapped with Uka Uka and Dr. Cortex in the Bone Yard (a level from Crash Bandicoot 3), he and Uka Uka actively try to escape the portal. As N. Tropy is arguing with Cortex about the chance to escape, Uka Uka with all his strength creates a Quantum rift (before passing out from exhaustion). Finally free, N. Tropy encourages Cortex to leave Uka Uka behind and they set off to conquer the multi-dimensions

In their next appearance, N. Tropy and Cortex are seen creating the Rift Generator to gain access to all dimensions. After Cortex dismisses N. Gin and N. Brio's projects, N. Tropy sends them to travel to the Hazardous Waste Dimension & Tranquility Falls Dimension respectively warning them to anticipate Crash & his allies to stop them.

Following the defeat of Dr. Cortex in the 11th Dimension, N. Tropy, through a hologram, ridicules him and reveals that he never intended to simply conquer the multiverse. He, with his new partner (his female dimensional counterpart from Tawna's timeline) plan to use the Rift Generator to recreate the timeline where they are gods and where everyone except for themselves were wiped from existence. Enraged by this betrayal, Cortex decides to join his enemies in stopping the N. Tropies.

Once Crash and his allies gather all four Quantum masks, they infiltrate Bermugula's orbit where N. Tropy and his dimensional counterpart command Nitrous Oxide to prevent their enemies from reaching the Rift Generator. Shortly afterwards the two N. Tropys begin flirting with each other (Much to Crash, Coco, Tawna, Nitrous Oxide, and Cortex's disgust and to Dingodile's amusement as they watch on screen). Later Tawna attempts to take the two doctors down on her own but is quickly defeated before Female N. Tropy mocks Tawna about killing her dimension's Crash and Coco. The rest of Team Crash arrives but is quickly separated from a Quantum Rift.

After Crash/Coco defeats N Tropy, Cortex attempts to mock Male N. Tropy for betraying him (using N. Tropy's very same words) before Dingodile and the Quantum Masks banish the two Doctor N Tropys into an unknown Quantum Rift, leaving their fates unknown.
