[[WMG: Hikari is Cthulhu.]]
Hikari is responsible for every Mass Extinction Event is Earth's history and Cthulhu and his minions caused the [[PhlebotinumKilledTheDinosaurs Permian extinction]]. Thus, Hikari is Cthulhu.
* Confirmed: Hikari and Akari together are the being responsible for both the mass extinctions and the sudden explosions of new, unique life afterward, as they eliminate creatures that they determine should be eliminated and bring into existence various organisms that had only existed as a potential before. Hikari is the part meant to destroy while Akari is the part meant to prevent the destruction of that which is still needed.
