Soundwave's original cassette force - small in size, but high on power!
LASERBEAK
In robot mode, Laserbeak was modified by Teletran One to resemble an Earthen condor (although why is unknown, as it modified all other Transformer's vehicle modes, and had supposedly percieved machines, not animals, as the dominant life-form on Earth). His original alternate mode on Cybertron was a cassette, and remains the same on Earth. Laserbeak has vast data storage capacity, and is equipped with a retractable zoom-lens camera mounted in his forehead for data collection in condor mode. He is equipped with two blasters under each wing, at least one of which is capable of independant flight (Ref: "More Than Meets The Eye"). Laserbeak has shown no indication that he is able to talk, only squawk, but he definitely sentient enough to have independant thoughts. Laserbeak is loyal to Soundwave and thusly Decepticon commander Megatron. His final fate is not recorded.
RAVAGE
Ravage resembles an Earthen panther in robot mode (although why is again uncertain, see above). In robot mode, Ravage is equipped with several stealth abilities. In deep shadow, he becomes invisble, and can project a protective field to block any electromagnetic emission from inside himself. Ravage's footfalls are imperceptible to the unaided audio reception module. He is armed with two hip-mounted fusion missiles, although he rarely uses them. In cassette mode, he has large storage capacity for data, apparently both audio and video.He has been seen to speak while relaying information in cassette mode (Ref: "More Than Meets The Eye").Ravage was among the Primitives recruited by Primacron's Assistant to battle the energy creature, Tornitron. Ravage was easily bested.
After the Great Wars, several Decepticons were granted amnesty. Ravage was one of them, but instead of retiring, Ravage was rebuilt as a Predacon.Sent back in time to prehistoric Earth by the Tripredacus Council to aid the Maximals in capturing the Predacon, Megatron, Ravage changed sides when he learned Megatron's true plan - to destroy Optimus Prime and alter history so the Decepticons would win the Great War. His transwarp ship desroyed the Axalon, but before he could see the fruition of Megatron's plans, the Maximal, Rattrap, set explosives in the ship's hold. The resultant blast tore Ravage apart. Presumably, his spark went to the Pit (aka The Inferno).
RUMBLE
Rumble is a dangerous Decepticon. In robot mode, he is capable of converting his arms into pile-drivers, which he can use to create earthquakes and tidal waves. These tremors are powerful enough to actually shake a gestalt warrior into it's component parts (Ref: Devastator in "Transformers: The Movie").Unlike his fellow cassettes, Rumble has never been seen gathering data - he has only been seen in battle. Furthermore, it is known that Laserbeak had a cassette mode on Cybertron, as did Ravage. Logic dictates that Rumble would too. However, this means that, as he transforms into an unaltered robot form, that Teletran One did not reconfigure him! The same discrepancy surrounds his twin brother, Frenzy. Rumble's final fate after the restoration of Cybertron's Golden Age is unrecorded.
