After the defeat of a smaller scale scouting force from the Dymethian Empire, the two heroes who averted it left the scene to avoid the authorities. The evidence would fade with self-destruct nanites the Empire use to prevent their technology from getting into enemy hands.
As they made it to the rooftops, the shorter of the two in orange and yellow armor and a flak jacket dress, watched as her comrade in teal with a red arm cannon went over different cuts and dents to his armor to see what needed repairs and what could be left to mend.
As she watched, a thought occurred to her.
"Oh, Relik!" she began. "I always wondered... i know you aren't the same kind of robot as most of us, but... do you ever wonder how that metal of yours heals itself?"
His purple optics glanced up in passing. "I", the man said, beginning a thought and realizing he had nowhere to go with it. "I... never gave a thought to that."
He stared at the arm cannon and his free hand in contemplation. Though mismatched - one a remainder of his old form with four barely articulated claws lining a gun barrel, and the other a functioning humanoid hand in black kevlar - they both felt equally "his", made of the same mysterious material at their core with full tactile feeling. He knows it originates from the Empire, as much of his history since his creation he wanted to forget, but he realized there weren't many machines that could self repair in that way.
"Do you think its... magic?" She chirped.
"...Magic?"
"Yeah! They can already do a lot of stuff with their minds. Maybe it's an enchanted metal!"
He felt a wide variety of ideas crop up in his mind. And while he was never as enthusiastic or imaginative as her, and as much as the rational part of him wrote it off as a mundane explanation... he had no easy answer right now that could rationally be differentiated from magic. Because in the end, wasn't magic inherently something that was innate, but unknown? After all, to exist, to be happening, it has to be real in some sense no matter what-
"-ik? You online?"
Oh drat, he got lost in semantics again.
"Oh. Yes, sorry Oskie. To... save myself some processing time, I think we can write it down as 'undefined' for now."
"Enchaaanted~", she practically crooned.
He would smile if he had a mouth beneath that faceplate. It was rarely a dull moment with her around.
