Dr. Nefarious

A robotic villain whose theft of the Dimensionator fractures reality across multiple dimensions.

In Ratchet & Clank: Rift Apart, set some time after Into the Nexus (2013), Doctor Nefarious is a central figure whose actions trigger a multiversal crisis. During a galactic parade on Corson V hosted by Captain Quark and Skid McMarx, Nefarious attacks to steal the Dimensionator, a device Clank repaired for Ratchet to find his lost Lombax family. In the ensuing struggle, Nefarious's interference causes the Dimensionator to misfire, creating random dimensional rifts that transport him, Ratchet, and Clank to an alternate universe. The Dimensionator is destroyed by the misfire, and the rifts damage the fabric of space-time, separating the trio.

Lore & Background

In this specific timeline, Dr. Nefarious finds himself in a throne room within an alternate universe. He deliberately impersonates Emperor Nefarious after realizing the Emperor is absent. Unlike his original self, this alternate version has never been defeated and rules over the galaxy with absolute authority. While Ratchet searches for Clank alone, Dr. Nefarious attempts to assume the identity of this omnipotent ruler, but the real Emperor Nefarious is present and later confronts him. He leverages his deception to send his new minions after both Ratchet and Rivet, a female Lombax resistance fighter. His manipulation allows him to operate from a position of ultimate power while hiding his true identity behind the persona of an undefeated emperor.

In Their Own Story

The conflict escalates when the real Emperor Nefarious arrives on the scene, easily defeating Ratchet and Rivet to reclaim the Dimensionator he had previously stolen via his alternate self. The real Emperor plans to use the device to eliminate Captain Quantum (the alternate Captain Qwark) and destroy the resistance. Later, as the resistance regroups, the emperor begins invading other dimensions, starting with Ratchet's home dimension. During the final battle, Dr. Nefarious joins the heroes' side; he grew irritated over how his alternate self treated him. Together, they defeat the Emperor and send him to his demise through a rift.

Reader's Guide

Dr. Nefarious serves as both an instigator of chaos and an unexpected ally in Rift Apart. His role shifts from antagonist to reluctant hero when he turns against his alternate counterpart, the undefeated Emperor Nefarious. The turning point occurs during the final confrontation where Ratchet, Clank, Rivet, Kit, and Dr. Nefarious unite to stop the Emperor's multiversal conquest. After the Emperor is defeated, the credits show a new status quo: Dr. Nefarious reunites with Lawrence, who is now a father, signaling a potential shift in his character arc within this saved reality.

Did You Know?

Villainous Origins and Betrayal

Doctor Nefarious serves as a pivotal antagonist within the Solana Galaxy conflict, initially introduced as the chief scientist working under Chairman Drek. While Drek focuses on dismantling planets to construct New Quartu for his displaced Blarg people, Nefarious harbors deep-seated resentment stemming from past mistreatment by Captain Qwark during his time as a Galactic Ranger. This personal grievance drives him to orchestrate a treacherous betrayal of his own employer. During the assault on the Deplanetizer, after Drek destroys the planet Novalis, Nefarious suddenly turns against the Chairman. He utilizes a specialized sheep-transforming weapon to incapacitate Drek, stuffing him into an escape pod and ejecting him toward New Quartu. This act marks Nefarious's transition from a subordinate scientist to the primary threat, seizing control of the Deplanetizer superweapon with malicious intent.

The Umbris Annihilation Plan

Upon assuming command of the Deplanetizer, Doctor Nefarious reveals his true objective: not merely planetary destruction for resources, but total galactic annihilation as revenge against Qwark. His strategy targets the planet Umbris, which possesses a highly unstable core capable of triggering a chain reaction that would vaporize every neighboring world in its vicinity. This plan represents an escalation beyond Drek's resource-driven motives, shifting the conflict to existential stakes for the entire Solana Galaxy. Nefarious successfully fires the Deplanetizer's laser toward Umbris, forcing the Rangers into a desperate confrontation. Although Captain Qwark initially intercepts Ratchet and Clank due to lingering jealousy, he eventually realizes his manipulation by Nefarious. The heroes manage to redirect the weapon's trajectory away from Umbris, inadvertently causing the beam to strike New Quartu where Drek had crash-landed, effectively ending the Chairman's threat while leaving Nefarious's own fate uncertain.

Confrontation and Apparent Demise

The climax of Doctor Nefarious's arc occurs during a final showdown aboard the Deplanetizer. After Ratchet, Clank, and a redeemed Qwark unite against him, Nefarious attempts to eliminate Qwark using his signature personal weapon, the RYNO, an acronym standing for 'Rip You a New One.' However, Ratchet intervenes just as the weapon is fired. In the ensuing chaos, Nefarious is seemingly disintegrated by the very energy of the Deplanetizer's laser chamber as he falls into it. This moment appears to mark his definitive defeat, allowing the heroes to escape via teleporter before the superweapon crashes into Umbris and vaporizes in the atmosphere. The Rangers subsequently return to Kerwan, believing the threat has been neutralized, while Qwark faces demotion for his role in the conflict.

Survival and Robotic Transformation

Despite his apparent destruction in the Deplanetizer's laser chamber, Doctor Nefarious is revealed to have survived through a mid-credits scene that recontextualizes his fate. The footage shows him stranded on the planet Umbris, where the extreme environmental conditions forced a drastic physical evolution. To survive the harsh reality of the planet he intended to destroy, his body was forcibly converted into a robotic form. This transformation suggests that Nefarious is not only alive but has undergone a fundamental change in his biology, potentially setting the stage for future conflicts. This revelation adds a layer of complexity to his character, indicating that his villainy and resilience extend beyond simple mortality, ensuring he remains a lingering threat within the Ratchet & Clank universe even after the film's main events conclude.

Incident on Corson V

Doctor Nefarious initiates the game's primary conflict by attacking a parade on Corson V celebrating Ratchet and Clank as galactic heroes. Hosted by Captain Quark, Skid McMarx, and Rusty Pete, the event is interrupted when Nefarious attempts to steal the Dimensionator. During the struggle, Ratchet unthinkingly shoots the device, causing it to malfunction. This accident triggers random dimensional rifts that transport Ratchet, Clank, and Dr. Nefarious to an alternate universe. The subsequent explosion of the Dimensionator in this new dimension damages space-time and separates the three characters.

The Alternate Emperor Deception

Upon arrival in the alternate universe, Dr. Nefarious finds himself in a throne room where he is mistaken for Emperor Nefarious, a version of himself who has never been defeated and rules the galaxy. While Ratchet searches for Clank elsewhere, Nefarious secretly assumes this imperial identity. He utilizes the position to command forces against his enemies, sending minions after Ratchet and Rivet while the real Emperor is absent on a conquest. This deception allows him to manipulate events from a position of supreme authority before the true ruler eventually returns.

Redemption and Final Battle

The dynamic shifts when the real Emperor Nefarious arrives, defeating Ratchet and Rivet to steal the Dimensionator for himself. As the resistance regroups, the Emperor begins invading other dimensions, including Ratchet's home dimension. In the final confrontation against the Emperor, Dr. Nefarious turns on his alternate self, driven by irritation over how he was treated. Alongside Ratchet, Clank, Rivet, and Kit, Dr. Nefarious helps defeat the Emperor and sends him to his demise through a rift. Following reality's repair, the credits depict Dr. Nefarious reuniting with Lawrence.
