The land of Equestria was always one filled with light and positivity, but the darkness has been amassing, the Sin, embodiments of the evil of ponies' hearts and souls, have struck, many ponies have died, and only 4 centers of civilization remain, Canterlot, Ponyville, Bearussia, and Neigh York, the last vestiges of hope for ponykind, and they are mere motes of substance waiting to be consumed.

Princess Luna, a powerful mare who has seen first-hoof into the abyss of darkness and evil, has used her and her sister Celestia's magic to summon warriors of light, heroes that will save the land of Equestria.

She was expecting 1, 2, maybe 3 tops, and if Lady Luck was on her side, 4, but she received, not 5 or even 6, but 15 fighters to help this task.

That's not what was surprising about them, what was surprising about them was that they were not even ponies.

(you do not have to have read Omega's Post-Humous Log to know what is going on) After killing Omega, who was overtaken by XV, Xero lived a full and prosperous life, he grew up, got smart, acquired an apprentice, he is an old man now, and MBORF has come for him. He's not scared, he will fight to his last breath, whenever that breath may be.
His death had led him somewhere he never would have expected, using his honed skills, gained proficiency in science in his mind, and compassion that had come from many years of raising an apprentice in his heart, and a revived health in his body, he will have to deal with something he never thought he would have to deal with.
Ponies.

(highly recommend watching the Xionic Madness series for a better context of Omega and everything about him)The leader of the tippy-top team of soldiers in the world, Omega the cyborg, was finally dead, killed by his former team mate Kary-08, a fully sentient android, even when he regains consciousness, he is now in... hell? He thought that's where he would end up, at least in some mildly charred rip-off of hell, but no, now he is in the land of Equestria, a utopia ruled by ponies and peace, and he's been through so much, he's more than willing to accept both. He is cripplingly cautious though, years on the battlefield have taught him that even in the brightest light, there is darkness, yet while nothing threatens him, he can't feel safe. Stripped of his powerful bio-mech armor, he finds himself feeling naked, despite his new companions and under-armor clothing, and puts his mind to it's greatest use, science, and it's least used use, friendship. Rated for Omega being a vulgar person and other stuff later on
