Tabuu was controlling the R.O.B squad on their own will. He was forcing them to make Subspace Bombs and making them like suicide bombs to the point that all of the R.O.B were extinct. I guess you can say that but you will later know why the Mii Team are the enemy this time. Just wait until the next chapters appear.
