*Rivet is a playable character in Rift Apart. She is a lombax from an alternate dimension, believed to be the dimensional counterpart of Ratchet. Rivet makes her debut in Rift Apart as a member of the Resistance force fighting against the evil Emperor Nefarious and his tyrannical empire.

When Clank gets separated from Ratchet, she takes him with her after finding him in Nefarious City following the Dimensionator's destruction. She later teams up with him and Ratchet to help them stop the dimensional cataclysm. On the way, she meets Kit, the counterpart of Clank, with whom she eventually forms a bond after a rocky start to their relationship.

Rivet is a lombax with white fur with pigeon blue stripes, thin dark eyebrows, a small light pink nose, and light blue eyes. The fur on her forehead resembles a tuft of hair. She wears a pair of black goggles with blue lenses on her head, silver hoop earrings in each ear (two on the right and one on the left), a black and gray jumpsuit with a silver belt, an orange scarf, a black left glove with two orange stripes almost at the end, and black boots with an orange detail. She also has a yellow bionic right arm which she used to replace her real right arm that she had lost from Kit.

Unlike the only other known female lombax, Angela Cross, she has a bushy tail similar to that of a raccoon or a fox and noticeably different from those of Ratchet and Alister Azimuth, who both have tufted tails similar to that of a lion. This may be because Rivet is from a different dimension, giving her anatomical differences. Rivet also uses a Hammer as her main weapon.

Rivet is heroic, sassy, quick to act, and light-hearted, making witty jokes in tense situations. She often sacrifices her safety and comfort to protect others. Rivet has an unbroken spirit, continuing to stand up to Nefarious despite always losing.Because most people Rivet encounters work for Emperor Nefarious, she has few friends; this leads her to become somewhat socially awkward, but also means that she is very protective of the few friends she has, including the morts, and Clank after befriending him. Rivet attempts to cheer others up when they are down; however, her aforementioned awkwardness means this can be ineffective.

Rivet suffers from PTSD as a result of losing her arm and her past failures. Her experiences have left her to become suspicious of everyone she meets as a potential threat, with an additional prejudice toward robots, especially due to the pirates and the Emperor's followers. This led her to dismiss Clank's story as preposterous until she scanned his brain to confirm it was true. She later was grateful for being able to work with Clank, leading her to trust Kit at first to the point of opening up about her past. Although her friendship with Kit fell apart after learning how Kit was responsible for her arm, she eventually grew past her mistrust and resolved to become teammates with her.

Rivet has many similarities with Ratchet in being heroic, headstrong, and light-hearted, and their similarities lead them to at times say the same words as one another. Rivet's trust issues are a trait she does not share with Ratchet, who did not have the same experience as Kit. Because of this, while Ratchet was hesitant to find the lombaxes and nervous about giving up his life in his dimension, Rivet had no such skepticism and was confused by Ratchet's, eager at the idea as she had fewer close family to give up. Despite this, she was also nervous about meeting Ratchet initially.*
