Mini-Cassette

Mini-Cassettes (also known as Cassette Warriors, Micro-Cassettes, Tape-Bots, or simply Cassettes) are Transformers whose alternate mode is an audio cassette. They can fit into the chest compartments of Blaster or Soundwave (while they can fit into either, they stick to the communicator of their own faction).

Many of the characters have communication or espionage roles.

Cartoon canon
The Mini-Cassettes were largely subordinate to Soundwave and Blaster, and very loyal to them. They spent much of their time stored away in their chest waiting to be called out when the situation required it. The mini-cassettes with beast forms were treated like pets and were generally (but not always) limited to growling animal vocalizations.

OOC Trivia
The toys of these figures have mini-cassettes in roughly 1:1 scale as altmodes. The main picture in this article features a standard cassette, which is larger.

The term Mini-Cassette is used in toy catalogs from 1985 onwards. It was common for cassette to be used elsewhere, such as toy instructions and fiction.
