Grey DeLisle voices Arcee, three female Autobots driven by a single consciousness, that transform into motorcycles. Functions as a field commander. Although given individual names in the official toyline, the sisters are collectively addressed as "Arcee" in the movie.
During development, the three bikes were first conceived to be able to combine into a single robot, and this ability can still be seen in the film's novelization. The three sisters are:
- A pink Ducati 848 called Arcee in the toyline.
- A blue Suzuki B-King 2008 called Chromia in the toyline.
- A purple MV Agusta F4 R312 called Elita One in the toyline. At some point, she was meant to be called Flareup.
All three motorcycles feature customizations performed by custom sportsbike builder retroSBK.
Arcee was initially meant to appear in the 2007 film as a robot that transformed from a single bike, but was ultimately dropped from it due to concerns of her being too small compared to the other bots, and the fact that the writers felt there was not enough time to explain her gender, despite her and several other female Transformers appearing in the 2007 film's toyline and tie-in comics. Whether to explain robotic gender or not was something the writers were unsure about, and it remained undecided until post-production, with the issue eventually remaining unaddressed in the finished film. She was then replaced by Ironhide.
Arcee's holographic riders are played by Erin Naas.
