The Diaclone Dashers!

Originally available in the Pre-TF line, they were released both in Japan and Italy. There were 3 of them: Drill, Sky, and F-1 (or if you prefer the Italian version, Zetar, Cromar, and Aragon).

Also known as Omnibots in the USA. :-) Like the Powerdashers, they were mailaway promos. But they had a Pre-TF beginning:
