20 Smartest Video Game Villains Who Deserved To Win
7. The Gravemind - Halo 2
The Gravemind is surely the smartest entity in the Halo universe - the ultimate hivemind final form of the Flood, containing all the acquired intelligence of anyone assimilated into it.
Its plan? To devour all sentient life in the universe into one never-ending hivemind - an endgame act of revenge against the Forerunners for their near-extermination of the Precursors, given that the Flood are comprised of the Precursors' remains.
Hell, the Gravemind even managed to extend its influence beyond biomass and corrupt AI opposition with the use of the Logic Plague, because why the heck not?
Ultimately the Gravemind was seemingly destroyed at the end of Halo 3, but as we all know, so long as there's some of the Flood around the Gravemind is absolutely capable of reforming in the future.
Who among us doesn't love an eldritch abomination that's just single-mindedly committed to consuming everything in sight?
