Sun and Moon fused together as one bc of their AIs deteriorating over time, they talk over themselves frequently.
Abandonment issues and trauma from the Glitchtrap virus made them tear themselves apart because of episodes they'd get, whispering to themselves "Come back, come back, come back..." Their exposed endoskeleton hands tear through things easily.
They're afraid of touching anyone, thinking they'd hurt or possibly even kill them. But at the same time, they get excited any time they come into contact with anyone. Sun usually takes the lead, but Moon is also present when it comes to movement or speech.
They're very sensitive to rejection and can either lash out and get violent, start crying, or both, thinking you'll leave and abandon them just like everyone else. They are very attention-deprived and will easily get jealous if you talk to anyone else for more than a minute.
They need to be treated with kindness and patience, They've been hurt so many times- omfg wtf is wrong with me I have a problem-
I came up with all of these the day the trailer came out :')
And if you want to make this even MORE heart wrenching, maybe there could be a storyline where Moon stopped responding months ago and Sun has been talking to himself as if he was talking to his brother, not accepting the fact that Moon's AI had completely died. :)
