Prim is a feline member of the order of the Space Knights.
Prim was a new recruit to the Solstar Order militia who trained at the same time as Rom, Livia, and Fy-Laa. After doing some null gravity training under Orphion and Diavod's supervision, the four decided to clean off in the showers. Prim expressed her confusion at Elonian grooming customs and the fact that Rom and Livia seemed to always be in heat. On her first field mission, she was teamed with Butin to investigate a volcano on Shrinn Island. Soon afterwards, she became one of the first Space Knights.
Prim was a part of a phalanx of Solstar Knights who confronted Unicron when he began attacking Elonia. When the phalanx's leader ignored Optimus Prime's warning against taking the planet-eater head on, Prim opined that they should have listened just before Unicron unleashed a blast of energy that killed her and the rest of the team.
