Micro (the stick figure) is created by a human named Geogory Dimmund. He, with his team, created Micro as a Super AI. For that, Micro must go undergo many stressful trials to form humanity inside him, much like real humans would do. One day, Micro had enough, fought back and escape to a game.

He hides in a game (Psychonaut or Earthbound, I'm not sure) and made his first friend. But then the human found him, so he brought his friend and they're starting to escape. Geogory send out an army of cursors to capture him. Micro opened a portal to the next world, but something went wrong.
