Mini-Cassette

Mini-Cassettes (also known as Cassette Warriors, Infiltration Troopers, or simply Cassettes) are a subspecies of small-sized Cybertronians from the planet Cybertron.

Anatomy
Mini-Cassettes share a similar biology to other Cybertronians, except they are about the same size as Humans and transform into audio cassettes. Mini-Cassettes have different types of robot modes, with the most common including:
 * Avianoids such as Laserbeak, Buzzsaw, Sundor, Garboil, and Squawktalk
 * Felines such as Ravage, Steeljaw, Stripes, Howlback, and Glit
 * Humanoids such as Rumble, Frenzy, Rewind, and Eject
 * Iguanodons such as Dile, Dairu, and Uriad
 * Apatosauruses such as Zaur, Zauru, and Uruaz

Animalistic Mini-Cassettes exclusive to the Autobots include Ramhorn, who is a rhinoceros; Graphy, who is a Pteranodon; and Noise, who is an Allosaurus. Animalistic Mini-Cassettes exclusive to the Decepticons include Ratbat and Wingthing, who are both bats; Beastbox, who is a gorilla; Overkill, who is a Ceratosaur; and Slugfest, who is a Stegosaurus.

In the Malgus cluster, Mini-Cassettes are Cybertronians created on Earth using AllSpark fragments. Two types of these Mini-Cassettes exist: condors that transform into electric guitars and bats that transform into keytars.

In the Uniend cluster, Mini-Cassettes instead transform into Cybertronian data disks.

Powers and abilities
Mini-Cassettes share many of the same abilities as Cybertronians.

Mini-Cassettes can generally fit into the chest compartments of Cybertronians such as Soundwave and Blaster.

Culture and society
Many of the Mini-Cassettes have communication or espionage roles.
