Nepeta was Equius' MOIRIAL and he absolutely adored her and saw her as a little sister. Sadly though, him being a high blood and her being a mid blood meant he would live longer than her.... And that day eventually came.... Nepeta had passed and he was yet indeed alone again.... Just like when his crush, Aradia, died Nepeta was there to comfort him but she was here no more.... So just like what he did with Aradia, he made a robot replica! That's when you were born as a Robotic version of Nepeta.

he was powering you on as you were sitting on his table.
