The Decepticons are seen as the ruthless enemies of the Autobots. They have no care for the human race and only want to see the Autobots destroyed. The Decepticons are led by the villainous Megatron. Part of the well known list of Decepticons are the Cassettes. They are Buzzsaw – a condor, Laserbeak – also a condor, Rumble – a robot, Frenzy – a robot, Ravage – a panther, Ratbat – a bat, Overkill – a two-legged dinosaur, Slugfest – a Stegosaurus, Squawktalk – a parrot, and Beastbox – an ape.
Megatron – Megatron is the leader of the Decepticons. He has destroyed many Autobots and leads the battle on Earth. Although he is considered the original leader there have been times that he was challenged for power, but has managed to survive and continue his lead.
Starscream – Starscream is known as the second-in-command for the Decepticons because of the combination of his intelligence, skill, agility and speed. Although he secretly wants to replace Megatron, he continues to fight with the Decepticons. He is probably best known to create the Combaticons.
Soundwave – Soundwave is a high ranking Decepticon who has the ability to hear faint sounds and the slight ability to read minds. He is known for his ability to carry the Decepticon cassette warriors. His alternate form is a Walkman.
Ravage – Ravage is stealthy and can become almost undetectable. Because of this he is used mainly as a spy. Ravage transforms into a panther as his alternate form. In the original cartoon he is portrayed almost as the Decepticon’s pet. He can be seen both in the original Transformers cartoon and in Beast Wars.
Frenzy – Another Decepticon Cassette, Frenzy is Rumble’s brother. This caused a little bit of confusion with the animated cartoon because their colours were occasionally switched around. Frenzy, like many of the cassettes, fights alongside Soundwave with pride.
Laserbeak – Although Laserbeak is loyal to Soundwave, that doesn’t mean that he’s the most confident of fighters. He traditionally fights in the distance or when he knows that he can win. Because of this, he usually is used as part of reconnaissance.
Bonecrusher – Bonecrusher is one of the many scouts for the Decepticons and is part of the sub-division of Constructicons. He is known for his demolition skills and transforms into the alternate form of a Bulldozer. He could form the giant Devastator when he merged with the other Constructicons (Scavenger, Scrapper, Hook, Long Haul, and Mixmaster).
Shockwave – Shockwave’s position in the Decepticons is the “military operations commander.” He was once the leader of the Decepticons after throwing over Megatron. He has the ability to fire electromagnetic beams.
