She is seen at the beginning of Rift Apart using a robot disguise in Nefarious City to blend in with it's robot inhabitants, whilst doing an undercover assignment for the Resistance to steal an important Infobot. Rivet is very proficient in combat and is not afraid to get her hands dirty in a mission. She however built a new robotic arm for herself and replaced it, giving her enhanced strength and new built-in gadgets to aid her in future. Years ago on a mission, Rivet had found a secret entrance inside the Imperial Zone into Nefarious Tower and attempted to sneak in alone, but was attacked by a powerful Nefarious Warbot on patrol and had her right arm severely damaged. As the most publicly known member of the Resistance, she is the one the Emperor has had the most encounters with and knows the most personally. She has built a name for herself over her many years of fighting the Empire and saving people's lives from the Emperor's forces, with wanted posters of her littering various walls around Nefarious City. The Morts grew to treat her as family over the many years of knowing her and despite their role officially as neutral in the galactic conflict, they have been harbouring her status as a highly wanted resistance fighter from the Empire. Rivet's base of operations, where she lives alone is on her foster home planet Sargasso, she grew up on this world and as a child worked for the Morts as a delivery person at their gelatonium factories.

With Emperor Nefarious' defeat in Megalopolis after his attempt to subjugate Ratchet and Clank's dimension with his armies, Rivet's universe was finally liberated from the oppression of him and his Empire, in thanks to the combined efforts of Ratchet, Clank, Rivet, Kit, the Resistance, the Savali monks, the allied Goons-4-Less members and the Space Pirates. The removal of these individuals would cripple the two factions and finally rid him of the last of his enemies. The Emperor had planned shortly before the events of Rift Apart took place, to vacate his throne and personally neutralize all key members of the Resistance and Space Pirates in quick succession, those being Phantom, MoyDoy, Captain Quantum, Clatchky and Rivet. Despite the Resistance fighting the Empire for about ten years, the Emperor on numerous occasions had bested them and his reign continued. The Resistance has a number of bases with Rivet's home base on Sargasso's Outpost L51 being also known as Resistance outpost four. It is likely there is no single leader and the group is instead supported by numerous key individuals of equal ranks. It is not known who founded it or who the leader is but Rivet does not seem to be a figure of authority over the others. She is seen as the face of the Resistance by most, with the mark of the movement being represented by the V-shape of a Lombax's head and ears. While the Resistance is an organization, Rivet is known as something of a lone wolf and tends to work alone on most occasions. The Resistance is one of the very last opposers to the Emperor's absolute rulership over the galaxy and the universe beyond, with it's most notable and well known member being the Lombax rebel Rivet. The movement was established ten years prior to the events of Rift Apart in the Polaris Galaxy on Corson V, after the planet was conquered by the Emperor and Nefarious City was constructed. The Resistance as it's known as, is a secretive organization in an alternate dimension, working with the intention of fighting back against the oppressive Nefarious Empire and it's tyrannical leader Emperor Nefarious.
