This is my first attempt at an actual first impression summary:
When Overwatch was first created, they had more members, one of these members was a scientist, this scientist was splicing different organisms, unbeknownst to everyone else, when the Omnic Crysis hit, the scientist and a few other members, were, unfortunately, killed, leaving the creation of the scientist stuck in a bunch of ruble, but eventually it escaped from the pile of destruction and it went into a sleep for many years, eventually a being of unimaginable power, INFINITE POWER, actually.
When the being went into the world, it decided that he wanted to take control of this creature, eventually corrupting and shifting bodies into the creature, merging themselves as one, the original creatures conscious was destroyed, completely, now the being is living as this creature and this is his story.
DISCLAIMER:
I don't own Overwatch or its characters, I own my own
