Cyzer was originally created by Eclipse the Darkling as the future and stronger generation of the Black Arms. While Cyzer was still a larvae in an egg, it and its kind were taken to Sonic's World on-board New Black Comet so they could feed on and grow stronger on the local life. When the New Black Comet was about to be obliterated by Team Dark and the Spider Troupe however, Cyzer and the Dark Arms' eggs were loaded onto an escape shuttle with Eclipse and send down to Sonic's World so the remainder of the Black Arms race could avoid extinction.
The shuttle eventually crashed in the Red Mountain Zone on Angel Island, where Cyzer was one of the few Dark Arms surviving the landing, along with Blurk, Cregal, and Rhygenta. After being found, Cyzer was tamed and raised by Eclipse, who swore vengeance at Shadow the Hedgehog for killing the Black Arms and Dark Arms. Following some days of nurturing, Eclipse left Cyzer and the others to find a better source of power to make the Dark Arms stronger.
Cyzer has a body shape reminiscent that of an lighting bolt and an eel. It has black skin, two cyan-glowing eyes with thin pupils, a cyan-gloving mouth with serrated teeth, and a single dorsal fin on the top of its head and its jaw.
Cyzer is a fierce Dark Arms hatchling with bad manners who tends to fight with its sibling Cregal for food.
- Cyzer's name is a portmanteau of its secondary color, "cyan", and its appearance shape, a "laser" (in this case, alternatively spelt as "lazer").
- Cyzer's design, unlike most other Dark Arms, is not completely based from one of the Wisps, but rather the Color Power from the Cyan Wisp, the Cyan Laser.
