Alt 2.0 was created as a replacement for the original Alt (some other robot who people seem to care about more than her) back in 2010.
Alt got jealous of Alt 2.0 and felt it was unfair to be replaced, so she got some magician dude named Zizz (who nobody even cares about) to hack into Alt 2.0. Zizz turned Alt 2.0 evil through Idiot Manipulation, Smell Manipulation, and Iggy Azalea.
Alt 2.0 ran off to a Freddy Fazbear's Pizza in Soviet Russia to work, well, as the computer, but she ended up scaring all the customers more than the animatronics with her scary face.
Alt 2.0 is known to hide inside Pop'n Music arcade machines, which are more popular in Japan than they are in America. The reason being is because of HER.
