How would you model Samael, the Hound of Resurrection from hellboy?

The Infinite Duplication thing is doable with a very finite amount of CP - roughly Zero, imo.

Just set aside a number of CPs for an Ally Group (other Sammaels). Each time this group grows significantly (beyond your CP expenditure), either pay additional points for your allies, or accept the fact that only X Sammaels out of the Y available ones will potentially help you.
That is, if *any* of these Sammaels are likely to help you, personally, at all. If they simply share similiar goals (Destroy Everything! Lay Eggs! Be Loved!), you could do them as simple NPCs and roleplay the alliance-forming aspect. Assuming that Sammael were a PC, of course, and assuming Sammies are smart enough to understand "Cooperation" in the first place.

In other words, I think that the "splitting up" thing is simply a Feature, a point-neutral side effect of "death."
