Windmill

Windmill is an Autobot in Generation 1 continuity.

Windmill personally designed and implemented the radar systems in Autobot HQ. An air defense technology specialist, and apparently a bit of a tech-geek, he enjoys the challenge of turning scrap metal into new laser weapons in his spare time. He's equipped with "kinetic intelligence" that combined with his "cyber-optic perception modem implant" somehow lets him track enemy forces anywhere in the galaxy. He still holds a grudge against the Decepticons for destroying his laboratory back on Cybertron. Windmill is extremely emphatic about the quality of his radar systems.

Toy
Windmill (1991) Windmill was an Action Master Elite, available only in the UK. He transforms into a high-impact, counterstrike helicopter.

(Note: The other three Action Master Elites all strongly resemble previous Transformers in robot mode. Windmill seems to be the exception to this, though his color scheme and alt-mode might suggest the Deluxe Autobot Whirl)
