Gearbot

Gearbot is a secondary character in Homebound. Gearbot is a robot made by Gear's brother. Her appearance resembles Gear, in a robotical way that is. It has been kept in secret in Gear's basement along with a copy resembling Gear's brother instead. It is known to have never been used due to a lack of a compatible "brain case", reason why the mind reading machine (protagonist of Gear's accident two years before SBURB) was developed in the first place.

First appearance
After future Gear's failure and death, her brain is transfered into Gearbot's body, allowing it to process future Gear's thoughts. This lets past Gear, or now Gearbot, to explain the details of her failure, attempting to prevent the same failure to happen over again. Gearbot is known to share future Gear's memories, while it owns a different and a way "soulless" personality. Later, Gear discovers the chip that gives the bot such a personality and alchemizes it mixing it along with The Vicious Mercenaria's book, giving the bot The Mercenaria's personality.

As The Mercenaria
After taking over The Mercenaria's personality, Gearbot starts to show a way more impulsive and careless personality, kind of resembling Kaarme's. It does not interract much with Gear herself, but is known to be "a douche" toward Rick. Later, during Professor Genesis conversation, she shows a less "vulgar" personality as she admits to have gone too far and was probably just trying to make some fun out of it. She also engages a conversation with Kaarme, revealing to have been a friendly and great leader through her adventures and how much she despises Kaarme for her behaviors toward her friends.
