Equius built the Five Nights at Freddy's robots. Freddy was based off of Eridan, Bonnie was based off of Nepeta, Chica was based off of Vriska, Foxy was based off of Karkat, The Puppet was based off of Gamzee, Mangle was based off of Sollux, and BB was based off of Feferi because of their personalities.
