planet. Nefarious makes a cameo appearance in Ratchet: Deadlocked alongside Lawrence, both still stuck on the asteroid as they pass by the just-destroyed ruins of the DreadZone Station. Enraged at his dashed hopes of rescue, Nefarious takes his anger out on Lawrence only to freeze up again. In Ratchet & Clank Future: Tools of Destruction, Nefarious's wallet can be found at the Imperial Fight Festival on planet Mukow as lost property, hinting at his presence in Emperor Tachyon's audience. It is later revealed that Space Pirates spotted them (but decided not to rescue them) when Nefarious was infuriated by Lawrence again and was in the middle of screaming at his butler when his trademark malfunction occurred. Dr. Nefarious later returns as the main antagonist in Ratchet & Clank: A Crack in Time (which is foreshadowed in the ending of Ratchet & Clank Future: Quest for Booty). He and Lawrence remained trapped on the asteroid until drifted into the Polaris Galaxy. Having crash-landed on the planet Zanifar and gained the trust of the local Fongoids, Nefarious reviews his past plans trying to comprehend how they have always failed, before learning of the existence of the Great Clock and devising a plan to use it to alter history so that villains always triumph over heroes (unaware of the fact that his plan would result in the entire Universe's destruction). Nefarious uses his trust with the Fongoids to have them build a fortress for himself, then summons and traps the creator of the Great Clock, Orvus, to extract information from him regarding the Clock's operation. Though Orvus remains defiant and escapes, Nefarious learns that Clank is the key to accessing the Clock. Two years later (when the game takes place), Nefarious moves from his fortress to a large space station crafted in the image of his head and begins a campaign to terrorize the Polaris Galaxy into submitting to his rule with aid from the mercenary Lord Vorselon and the robotic Valkyries. His plans to harness the Great Clock have not abated, and he orders Lawrence to observe Clank in secret from within the Clock. After Clank opens the Orvus Chamber, Lawrence knocks him out and reports the news to Nefarious. The doctor then gleefully starts "Unnecessarily Evil Initiative Omega-91" by using Clank as bait to lure Ratchet into a Valkyrie ambush. With "help" from Captain Qwark, Ratchet and Clank reunite and infiltrate
