A virus is less cool though. I've improved my symbiote idea. The symbiote actually has a mind of its own, making it a being in its own right. The traitor astartes would recognize the symbiote as their leader, along with whoever it is attached to. Obviously the symbiote would choose whoever is most worthy, possibly even a non-astartes. That opens up, in my opinion, more possibilities for Chaos in this timeline. In realtime, who would be recognized as more of a leader figure, a traitor chapter master or a traitor guardsmen general? The chapter master right? The symbiote would eliminate that factor. Anyone from criminals to Imperial soldiers to a tech priest would be possible.
