This is a list of characters appearing in the original American Transformers cartoon, first aired between 1984 and 1987.

Cassette warriors (or "Mini-Cassettes", or simply "Cassettes") are tiny transformers; they are no taller than the humans. Their alternate mode is that of a microcassette

Origins of the Cassette warriors

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 can't 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.

Rewind Cassette Tape Transformers: The Movie Madman's Paradise Townsend Coleman Alive

Ramhorn Rhino/Cassette Tape Scramble City Call of the Primitives John Hostetter Alive
Extremely nasty. Eager for battle. Only speaks in one episode, in which he stutters. Otherwise makes only rhino noises
Steeljaw Lion/Cassette Tape Scramble City The Return of Optimus Prime (Part 2) Frank Welker (animal noises only) Alive
Chose to first fly in his first appearance (flight of course for Autobots is impossible). According to Blaster, "can sniff out any trail, whether it's hot or not."

The Decepticon Mini-Cassettes

All of them are housed in Soundwave's breast.

Name Alternate mode First appearance Last appearance Voiced by Status alive
Laserbeak Condor/Cassette Tape More Than Meets the Eye (Part 1) Web World Frank Welker (animal noises only) Alive
Laserbeak is one of the few Transformers whose robot mode is not a humanoid. When on Cybertron, his main speciality had been to interrogate the Autobot prisoners, but on the Earth he became the best Decepticon spy. As a bird, Laserbeak is usually sent on reconnaissance missions, but he is worthless as a warrior, because of his cowardice. Nonetheless, Laserbeak is one of Megatron's pets; one can often see him sitting on Megatron's hand or shoulder.
Rumble Cassette Tape More Than Meets the Eye (Part 1) Five Faces of Darkness (Part 3) Frank Welker Alive
Rumble is a sort of a street-thug robot. His arms become piledrivers which he can use to cause earthquakes, and also to create fissures.
Ravage Panther/Cassette Tape More Than Meets the Eye (Part 1) Call of the Primitives Frank Welker (animal noises only, with one exception) Alive
Ravage is one of the Transformers whose robot mode is a beast. Also, he is one of the most hidden and treacherous Decepticons, acting in the darkness only. As a panther, he is able to move with more stealth than other Decepticons. He is Soundwave's pet.
Frenzy Cassette Tape Countdown to Extinction The Transformers: The Movie (omitting one possible animation error) Frank Welker Alive
Shares his appearance, pile-driver ability, and street-thug personality with Rumble. They consider Frenzy to be more smart and brave than Rumble, but he appears much less frequently in the series than his "twin brother".
Buzzsaw Condor/Cassette Tape City of Steel Transformers: The Movie Frank Welker (animal noises only) Unknown
A civil and sophisticated creature, but also one of the cruelest Decepticons. Usually deployed with the more frequently featured Laserbeak for scouting or attacks.
Ratbat Bat/Cassette Tape Transformers: The Movie The Return of Optimus Prime (Part 1) Frank Welker (animal noises only) Alive
The smallest of the Mini-Cassettes (his size never exceedes that of a real bat). In his beast mode, he is used as a spy in places Laserbeak is unable to reach. A skilled geologist.
Slugfest Stegosaurus Call of the Primitives Call of the Primitives, only appearance Frank Welker Unknown
A cassette ejected from Soundwave when called along with the other primitives. In his dinosaurus mode, he is an empty-headed destruction machine.[1] In the cassette mode, he can serve only as a messenger, because of his extreme stupidity.
Overkill/Buzzkill Tyrannosaurus rex Call of the Primitives Call of the Primitives, only appearance Frank Welker Unknown
According to his Tech Spec,[2] he is a serviceable warrior which never stops doing something until he runs out of fuel. But in the series, he appears only as a cassette ejected from Soundwave when called along with the other primitives.
