Loading Screen: Dr. Primitive

Dr. Primitive is member #64 of the Genius Society, an Emanator of Erudition,[1] and a notorious criminal who was known for his atavistic experiments.

Profile

Dr. Primitive is an intergalactic criminal known for his planet-spanning experiments, ruining prosperous interstellar civilizations at the end of his work. For instance, Larose was once stranded on a planet maimed by Dr. Primitive, where the inhabitants were all transformed into apes.[2] He spent his life running away from interstellar pursuers for the great crimes he had committed. He seemed to enjoy the thrill of being pursued, always keeping a carefully managed distance from those who were hunting him, never too close to be caught nor too far to be untraceable. Astrophysicists from the Intelligentsia Guild could not understand the principles of his gravity-capture technology.[3]

According to a drunk Galaxy Ranger, Device IX is where all of Dr. Primitive's secrets lie,[4] and another potential Galaxy Ranger was able to sell his robes on Device IX's black market.[5]

Dr. Primitive has his own set of researchers who formed the AtaviSearch Forest faction. They are classified under various levels: BananAdvisors, Denisovans, and Apes, of which they are classified into two categories: Combat and Research Apes.[6]

Appearance

Screwllum does not know Dr. Primitive's true identity, but mentions that some believe that he is an inorganic entity due to his previous transgressions against humanity.[7]

Story

The Galaxy Rangers were one of the groups that pursued Dr. Primitive. After thwarting his attempted rebellion and protecting the Thousand-Tree Greenwood on Vonwacq, the Rangers gradually began to decline.[8] It is rumored that they eventually fell victim to Dr. Primitive's vengeance,[9] though the details remain unknown. A tale spread by the Masked Fools claims that he transformed them into gibbons, but Boothill dismisses these rumors.[10]

Lygus states that Dr. Primitive attempted to take action against the Theory of Four Apocalypses, but chose the wrong allies, and now only wild animals keep him company.[11]

During the meeting on the Herta Space Station to select a fifth genius for the Simulated Universe project, Screwllum suggested inviting Dr. Primitive, but Herta immediately rejected the idea, preferring to keep the project free of scandal.[7] Although his current whereabouts remain unknown, the Galaxy Rangers continue to search for him.[12] After resolving Professor Primon's memetic virus incident at Paperfold University, Mr. Reca offered to tell Rappa where Dr. Primitive had gone.[13]

When Herta and Screwllum convened the fourth meeting of the Genius Society, prior to Battle of Amphoreus, Dr. Primitive was among the four who agreed to join, alongside Ruan Mei, Acha, and Polka Kakamond. Unlike the others, however, he participated purely for his own amusement.[14]

Trivia

  • According to the Masked Fool Sparkle, Dr. Primitive is a huge fan of bananas.[15]

  • One of the theories proposed by academics regarding the sudden destruction of the planet Izumo was that it was another appalling experiment of Dr. Primitive's.[17]
