Starcraft, Zerg overmind holds control of the zerg, creates kerrigan, kerrigan gets loose of the zerg overmind's control, Overmind dies, kerrigan now has control of the zerg.
Warcraft, LK holds control of the undead, creates sylvanas, sylvanas gets loose of LK's control, LK dies, Sylvanas now holds control of the undead.
- Thoughts on this?
edit: i didnt take into account the change of kerrigan at the end of SC2 due to simply there not being enough info about what's going on :>
