Chromia converts from a Suzuki B-King to... a unicycle. Her vehicle mode weapon can attach as a display stand for either mode, ironically making a unicyclebot one of the most stable robot-modes. In robot mode, there is a spring-loaded missile between the tailpipes on Chromia's left hand in addition to the aforementioned non-firing blaster-stand. There is also a piece on the bottom of the vehicle mode (or back of the robot mode) that folds out, but there is no indication in the instructions as to what this piece is for. It appears to be part of an unmentioned combiner gimmick for the Arcee triplets, as it locks together with a similar piece on Arcee, with room for a third robot to connect.
