Fiction
Prime cartoon
- Voice actor: Shizuka Itō (Japanese)
At some point, R.A. and B.2 got infected with Dark Energon... which mostly just made them lazy. Arc joked about their sloth, which annoyed them both. Infiltration Transformation! Battleship Nemesis When B.H. was being chased by Scraplets, Arc rather unhelpfully suggested that the running would do him some good so he could lose weight. Eventually she and C.L. decided to combine ino a combo weapon to help B.H., but she ended up blade-end into C.L.'s gunbarrel, forming nothing of any use whatsoever. Freezing Transformation!? Terror of the Minicons Once free of the Scraplets, B.H. wanted to get stronger, so he, Arc and C.L. combined to form the Galaxy Launcher Super Combo Weapon. In their excitement, they accidentally blew a hole in the studio. Secret Sword Transformation! Introducing Wheeljack
Arc put on a pair of silly heart-shaped sunglasses as part of the Microns' tenth-episode celebrations. All-Out Assault Transformation! The Pair of Assassins When Zamu and Gra entered the studio, O.P. kinda got jerkass on them, ranting and turning black as if infected with Dark Energon. Arc wondered out loud just what was in his drink. Acceleration Transformation! Speed Match! She joined R.A. and B.2 in preparing for a big announcement... when the studio walls fell away and revealed the towering Gari Robo-kun, which terrified them all because ye gods is that thing scary. Mystery Insect Transformation! Forest of the Spider Woman!

Notes
- Arc's name is pronounced as it would be in French, with a guttural R, and not as the English word "arc" (written in Japanese as アーク āku).
- In her first Arms Micron Theater appearance, her eyes were uncolored. By the second appearance, she got the Autobot-blue eyes the other CG models got.
