If the Actionmaster partners are just AI and don't count then it stands to reason that the Vehicons from Prime and the drones from Beast Machines who are also described as AI don't count.
I always read the Actionmaster partners bio as having personality so I think they count. Combiners with individual robot modes count individually but not their combined mode.
King posiedon (spelt right? probably not) from Masterforce was 4 drones and Turtler who combined so what does he count as?
