The name 'Astroforce' is too cool to leave as a one-off joke about remote control trains for Astrotrain. So, I'm gonna try and turn it into actual transformers.
To give Astrotrain something of an actual character (arc), he gets put in charge of a group of smaller transformers. Ones that he initally just sort of bosses around for a while, until a cataclysmic blunder causes half of them to lose their lives, and the other half to lose their respect for him.
These being 'cons that were to be tough enough to withstand atmospheric re-entry being...almost impressive how he lost half so quickly. Leaving him humiliated, but also shaken. Having never had actual control over others, and not realizing he was responsible for them, nor what it actually felt like to lose/fail them. He becomes much more protective over them, and undergoes a sort of maturation to leadership arc, but for a Decepticon.
