Cave Johnson

"I don't want your damn lemons! What am I supposed to do with these?!" - Cave Johnson

Cave Johnson is a character from the Portal universe.

He is voiced by J.K. Simmons.

Cave Johnson is the energenic, eccentric, but highly motivated CEO and founder of Aperture Science (or Aperature Laboratories as stated by the company's logo). His business career began in the early 1940's as Aperture Fixtures, which first started as a Shower Curtain manufacturer. Sometime later, he bought out a salt mine cavern in Upper Michigan and converted it into the company's main facility.

He and his company started to prosper by the 1950's, and started to take a broader approach to science inituatives, although he knows little about the subject. He then started developing Quantum Tunneling Devices, Long Fall Boots, and others, and had them tested by skilled individuals, namely Astronauts, Olympians, and War Heroes.

By the 1980's, Cave became severely ill from exposure to Moon Rock Dust, which, in the Portal universe, is considered very poisonous. During the 80's, his appearence became more sinister looking, but this is only because he was growing sicker and sicker. Looking at an imminent death, Cave ordered his technicians and engineers to develop an Artificial Intelligence system to hopefully cheat death. If he were to die, Cave ordered his ever loyal assistant Caroline to succeed as CEO of Aperture and have her uploaded in to the GLaDOS System. Cave Johnson died in the late 1980's, before the GLaDOS System could be completed, therefor Caroline was uploaded into the system.
