Dream Machine

The Dream Machine is an alien intelligence created at some point in the distant past by the race that would evolve into the Martians - breaking away from its original creators many centuries before the events of the "War of the Worlds" the machine would travel across the Multiverse absorbing the imagination of entire worlds, amassing ever more power until ascending to near-godlike status.

Yet as terrifyingly powerful as the Dream Machine became it was not content and spread ever further - in the end it took the power of Caprice to prevent the Dream Machine from completely consuming the imagination of "Universe Prime".

Reduced to the size of an atom by Caprice the Dream Machine would take thousands of years to grow to the size of a 3-inch marble, at which point it began to travel from world to world absorbing imagination and growing little by little in the process.

Caprice became aware of the Dream Machine's return soon after but the aggression of The Presence coupled with numerous other threats left her unable to act quick enough to destroy the entity in full - thus she sent The Immortals to try and stop the Dream Machine alongside several allies.

(NOTE: The Dream Machine is an upcoming antagonist for a "cosmic" event, thus has a much larger-scale backstory and scope - the full extent of which will not be revealed until nearer the time)

Powers / Abilities
The Dream Machine is capable of absorbing imagination, which allows it to grow to unimaginable levels of power - this coupled with its desire to completely conquer time and space makes it amongst the most powerful threats the Immortals have ever encountered..
