Gideon-bot

The  was a robot made by Old Man McGucket for Gideon Gleeful.

History
Its destruction was foreshadowed as it briefly flashed on Bill Cipher's body in "Dreamscaperers."

It made its physical appearance in "Gideon Rises" after Gideon stole Journal 3 from Dipper. Later in the episode, after Gideon learns that there are three journals, not two, he uses the completed Gideon-bot to catch up to the bus Dipper and Mabel were on that was headed back to Piedmont, California. The Gideon-bot rips off the roof of the bus while Dipper and Mabel run on to a bridge in hopes of escaping. Gideon catches them and demands to know where Journal 1 is. Dipper is then confused and doesn't know what he is talking about, so Gideon uses the Gideon-bot to pick them up, and it throws Dipper on top of a cliff. He then walks away with Mabel, with plans to make her his queen. Dipper runs off of the cliff and breaks into the Gideon-bot through its eye. Gideon and Dipper fight, almost destroying the bridge and beating up the robot at the same time. Dipper defeats Gideon but the Gideon-bot falls off the bridge. It crashes onto the ground and explodes into pieces.

Appearance
The Gideon-bot is constructed to look like Gideon, but its right half is unpainted. Its cheeks glow red while its wrists, eyes, and ankles glow a bright yellow. Also, inside the machine is a control centre where Gideon is able to control the robot's movements.
