Cassette warriors (or "Mini-Cassettes", or simply "Cassettes"or “Mini-Cons” like in Transformers Robots in disguise) are tiny Transformers; they are no taller than the humans. Their alternate mode is that of a microcassette.

According to The Transformers' version, in the days of Megatron, Decepticons developed the art of espionage using cassette technology. Their first cassette, Laserbeak, could fly undetected into any Autobot stronghold, record information and then return to base. Then the Decepticons decided to increase their spying abilities with Ratbat. As a bat, Ratbat can hide in crevices that Laserbeak cannot reach, and is especially effective in tunnels, caves or in the darkness of space. Ratbat records from the Autobots' most carefully guarded secrets. The Autobots had no choice but to strike back with these Decepticon techniques of stealth, building their own force of cassette Transformers, with Blaster as their guardian. They constructed Ramhorn, the rhino, who can use animalistic force if cornered, and Steeljaw, the lion, who can crawl through the foliage of any alien world, to sneak up on Decepticons. They also bolstered their cassette force with Rewind and Eject, who can transform to robot mode and use more conventional fighting force techniques.

The alternate version of the Cassette warriors' origin is stated in the animated series. According to this version, they (or, at any rate, the beast-moded ones) were once created by the divine inventor Primacron.
