Brainwashing is a tool used by Rubixia in Scott Cameron Takes Off.
As seen in SCTO Redux, brainwashing allows Rubixia to make prisoners forget memories, and/or make new state-loyal memories. It has been used twice:
¶ FIRST SEEN: SCOTT CAMERON
Scott is brought into the facility in SCTO Redux 4. He is brainwashed to become a Rubixian citizen, working in Rubixia.
However, brainwashing is only permanent on smart individuals, so after he sees Milera Onne in Rubixia, he regains his memory.
¶ MILERA ONNE
Milera is brainwashed in SCTO Redux 6. She is made to forget about Scott Cameron, however she is smart, and has longer effects. This ties into Season 3 of Scott Cameron Takes Off, where Scott and Milera break back into Rubixia to get her memories back.
