Chameleon and Khameleon I can see why Boon wouldn't have return for obvious reasons. Drahmin I'm not surprised about either, though Moloch was a rather fun sub-boss at least. I believe Boon also said that Hsu Hao would never return, as he was also one of Boon's least favorites, and much hated by John Vogel.
