W Cassettebot

The W Cassettebots are an Autobot sub-group from The Headmasters portion of the Generation 1 continuity family.

The W Cassettebots (aka "Double Cassettebots") are a sub-group of the Autobot Mini-Cassettes sub-group. Made up of dinosaur-robots, they can double-up with a partner to form a humanoid robot.

The W Cassettebots are:

• Graphy - Pterosaur
• Noise - Allosaurus

• They combine to form Decibel.

• Dial - Iguanodon
• Saur - Apatosaurus

• The combine to form Legout.

Trivia

• The "W" is apparently Japan's method of denoting "double". It was also used for the Micromaster Combiners during Return of Convoy, which were denoted the "W Teams".

• It is unknown if the pairings of Grand Slam/Raindance and Beastbox/Squawktalk are considered W Cassettebots (or W Cassettetron, in the case of Beastbox and Squawktalk). Those pairings were not sold at normal retail in Japan, only offered as mail-aways.
