Iridium's camouflage is a realm car (from the Metro Realm) and Battle Spec, which first appeared in The Speed of Silence. Once in Breaking Point, Iridium's camouflage, when this disguised car saved Shirako, is Rollin' Thunder in the Neon-Pipeline Realm. Tezla's Nitrium changed Iridium's camouflage back into the original car after its camouflage interruption. Iridium has been transformed into 2 Magnesium motorcycles. Iridium is the first car to be in the Acceledrome and Iridium's camouflage is RD-02, only appeared in The Ultimate Race.
- It is the first Silencerz car to be named after an element in pure form, others are Unobtanium, Technetium, Titanium, and Magnesium.
