Emet Rotter

Emet Rotter is the final main protagonist of The Angel's Game and returns in APCollection as the tritagonist.

The Angel's Game
Shortly after Joshua Rallus Harris commited suicide, The Dweller's energy merged with Josh and together they became a more powerful entity know as Emet Rotter. During The Creature and The Other's arrival at Stephen Patrick's house, Emet Rotter managed to destroy The Creature's influence over Austin Bradley and thus destroying The Other personality and causing Austin to sacrifice himself in order to save his friends.

APCollection
It was revealed that Emet infected both Stephen Patrick and Alana Hudson with The Dweller's energy, giving birth to the riftling hybrid and serial killer Mr. Collector and another riftling know as The Dreamer. Emet then traveled to another universe using The Rift and RHO 3 as his host. Emet eventually absorded The Dreamer's assimilated Josh, creating the immensely powerful riftling know as The Dweller Reborn.
