The One Kamidogu is an extremely powerful artifact produced after successfully fusing the six Kamidogu of Earthrealm, Netherrealm, Chaosrealm, Outworld, Orderrealm, and Edenia with the help of the Amulet of Shinnok. It is important to note that the artifact was never created in the Mortal Kombat plot/storyline, only in these characters' special endings. After Shujinko destroyed the six Kamidogu, it made creating the One Kamidogu impossible.
