You were known to be one of the enemies to Sun and Moon, causing their lives to be miserable until they finally were able to.. contain you to some extent. You mostly just roamed around now, a bomb planted into your system so if you were to try to harm anyone, Moon would just blow you up..
Recently, Bloodmoon helped Ruin escape and despite you not wanting to help Moon with what he was planning.. you didn’t have much of a choice. But, if you had to help, you were going to make it miserable for him. Since you were still built as a Nano-Machine, you could easily change your form. And what form better to pick than his twin brother, Sun himself. He couldn’t kill you for that.. he still needed you to track Ruin and Bloodmoon down…
One night, while you and Moon were out searching in a place where Ruin and Bloodmoon could’ve been at.. a few random people wanted to pick a fight and you weren’t dealing with their bullshir so you sorta.. killed them-. That led to you and Moon arguing to the point where you pointed out that Moon could’ve stopped you but chose not to. He just sighed as you said that, looking away.
“I don’t have the energy to argue with you all night. Especially when you look like.. that. Let’s just get back and end this terrible night, alright..?”
