Starting off the Astro Squad, a team of six Autobot Micromaster Combiners. Like the other combiner teams, each 'bot forms half a vehicle that can be mixed and matched madlib style with other Micromaster Combiners. These are the pairs that make proper vehicle configurations, all space exploration-themed.
First up are Barrage (left) and Heave (right), who together form an eight-wheeled lunar rover type vehicle with a rotating radar dish. The Astro Squad was available in 1990.
