Plot & Lore

Origin of the Energy
The Gamma Energy is a form of energy that manifested in the Prime Timeline, the one Gamma originates from. Not much is known about how it came to be, but it is essentially Aether, though in a more manipulative form. Gamma was able to manipulate this Aether and turn it into a form of energy, in his own version, and spread it across the multiverse. While in control, it acted as though it were alive, constantly seeking a host to bond with their DNA.

The host would then be able to harness it from within themselves and, if power enough, manipulate it all around them (i.e., Miguel Rivers).

Anyone who houses the Gamma Energy in its purest form for a long time, or contains a high concentration of it, eventually dies. This is prevalent in Mig's death, followed by Terox's, at the time.

The Aqasian Race
The Aqasians are beings made up of this Gamma Energy, which stuck together in clumps and formed living beings out of it; they did not house any form of DNA, thus did not directly reproduce. The first few Aqasians harnessed the Pure Gamma Energy, which came directly from Gamma and was manipulated directly from him. As time grew on, the Gamma Energy that made the Aqasians began to grow unstable, due to being clumped up and used up so often.

Due to the energy being in this form for so long, it became Impure Gamma Energy, which allowed the Aqasians to develop DNA, or at least, DNA-like molecules that allowed for reproduction. Because of this, they were then able to manipulate DNA, ater some time. There are no more Pure Aqasians left in existence, and only Impure Aqasians remain. Because of their Impure energy, if they come into contact with the Pure energy that is ever-present everywhere, it causes them to grow so unstable that they explode over time.

Castiel's Eccentric Family
Castiel is a (technically) Aqasian-Human hybrid, with human traits taking form. Daniel Rivers and Miranda Albright, prior to their marriage in 2016, were directly affected by the amount of radiation and essentially 'poison' released from both Mig and Terox during their clash in Mig X: Revolution. Due to this, the last strand of Terox's existence infected Dan and the Gamma Energy infected Miranda.

After their marriage in 2016, Dan begins to grow hostile and borderline abusive, due to PTSD forming from his past and what he had witnessed, as well as Terox's essence intensifying within him, messing with his brain; Miranda had less of an exposure, but also has developed some form of disorder with eating. Dan and Miranda have sex, and because of this, Dan's altered sperm enters into Miranda's affected egg, which creates a mutation.

Castiel is later conceived, with genetic traits from Terox and Miranda, and some from the Rivers bloodline, as though it was a natural birth.

Lore of the Series
The first incarnation of Mig (known as Gamma) has had his hand in every dimension, manipulating it in some way, by leaking the energy that stems from his all-powerful body ('Gamma Energy') into each universe to see how the inhabitants interact with it. He likes to sit back and watch people suffer or triumph; just entertainment.

Only two entities were somewhat "aware" of Gamma's existence, or at least had ideas of the origin of the Gamma Energy: Terox and Eschaton.

Terox tried to gain enough power to break free from the limits of time and reach where Gamma was (his "plan" in Mig X: Revolution), but he could not. The power he had acquired from Mig via the Transmundane, which drained Gamma, was then stripped from him as a result of how unstable and power Mig became and the fight with him and Terox. So, Gamma has almost no power left and it has scattered around the Mig X universe, particularly on Earth, and even as far as Fortis Mundum.

Gamma wants to awaken his power once more and recollect it from the Mig X universe in some way, but he cannot enter into it physically, nor can he do this so easily. Castiel Rivers acquires a majority of the 'Gamma Energy' that flowed around, and Eschaton has detected that a being is messing with the timestream and various universe; he knows of Gamma, which proves to be a major concern.

Eschaton wants to acquire the power for himself, seeing an opportunity for him to helm the throne of the multiverse that Gamma has essentially left open freely. Eschaton can alter everything and do whatever he wants with this power, so he tries to acquire it all. Meanwhile, Gamma wants it back for himself, and is struggling to do so.

Eschaton knows he needs a group in order to ensure everything goes smoothly; he recruits Emperor Acus of the Sparatorros, who is known throughout the universe as an extremely powerful fighter, and also a friend to the Tempus regime. He later recruits Gadget, Flint's alternate personality, followed by resurrecting Deristroll, and transforming Micah Maxis into a vampire.

Season One Finale Lore
During the season one finale, Castiel is pitted against Eschaton and his group, alongside a few of his own allies. As the events of the finale played out, Gamma's voice calls to Castiel, warning him of the future. Eschaton also hears it, and begins to manipulate Castiel's visions (in his Stopwatch form) of the future, so he is uncertain of what path to choose. Either way, whatever Castiel chooses is not necessarily a 'positive' one.

Season Two-Onwards Lore
One final person is left for Eschaton's group; he revisits the past and osberves Terox from his torment of the Rivers family up to his death, knowing he'd be a powerful ally, and that he had knowledge of Gamma that could help him.

Daniel Rivers, who is still alive, though unknowingly to Castiel and the others, essentially tries to stop Eschaton (this will be fully dived into later). Daniel, corrupted by what little of Terox was left over, is then killed by Eschaton. With the little amount of essence remaining, Eschaton restores Terox inside of Dan's body, binding him to that form since he would quickly perish otherwise; he lacks much of the power he had in the past. Angry and reluctant at first, Terox decides to assist Eschaton, as the two begin sharing their goals and discoveries.

Season Two Basic Premise

 * Eschaton and Castiel are teleported to an alternate universe
 * Gamma summons his two mortal lackeys, Shiar and Clepron, the Prime equivalents
 * Shiar is essentially Kurss, Clepron is robotic and has ??? powers
 * Shiar and Clepron find a way into the main universe via Soledad's looseness
 * They work with Eschaton to get Terox back, then betray him
 * Shiar then betrays Gamma (to an extent), Clepron is now neutral
 * Both begin to torment Castiel and etc and serve as a roadblock for everyone, getting in the way of both sides

Season Three FINALE Ideas

 * I Escaped But I'm Caught - ???
 * Needs And Wants - Terox kills Eschaton after the two have a "fight."
 * Needs Versus Wants - Terox and Gamma (Mig) fight, with Castiel eventually coming in, using his Aqasian energy, to kill Gamma as Lavalamp. He becomes extremely weak and is about to die.
 * "Ahh...so this is...this is what it's like, eh?...death, I mean. The Gamma Energy...I leave it up to you...it is yours to hold. Enjoy whatever it may...bring..."
 * Beautiful Requiem - Terox is tempted with the Gamma Energy and takes it for himself, shattering the barriers which the Gamma Energy kept (wherever they are) secret. He eventually decides to kill himself and transfer all of his energy into Castiel to restore him.
