Overload is a peculiar design that breaks the established pattern of Mini-Con interaction set by Armada. For most of the line, the Autobots or Decepticons are fully separate characters who are enhanced / powered up by affixing Mini-Cons onto parts of their body (via "Powerlinx" ports). The Mini-Cons are separate characters, thus I've been drawing them paired together in a single drawing. Rollout is unusual in that he is essential to making Overload's robot mode, as he fills an otherwise gaping chest cavity. For that reason, I've drawn Rollout as an inset, since he's also in the middle of Overload's chest.
In some fiction, Rollout and Overload are the same character; just one is a powered up version of the other. In other stories, they are distinct entities. Rollout turns into the semi cab tractor while Overload turns into a massive artillery-laden trailer. Overload also turns into a weapons harness that can be worn by larger 'bots, such as the super-powered version of Optimus Prime.
