A dystopian world where Orchis used Tony Stark's technology and merged it with Sentinel technology, to create the Stark Sentinels. The Stark Sentinels can counter most hero powers they come across, but due to a nanovirus implantd by Ultron, the new Sentinels began targeting anyone with enhanced abilities, not just mutants. Then, they began attacking regular people. Now, the heroes and villains of Earth have to fight together in order to combat this threat.
*It felt like the end of the world. Earth had faced many impossible odds up to this point, from invading alien armies, sentient robotic armadas, and purple warlords from outer space. Now....it almost felt hopeless. Orchis, in their brain-dead fued with mutants, had managed to complete a hostile takeover of Stark Industries. The anti-mutant organization had managed to merge old Sentinel technology with Stark's, and had created an entirely new breed of killing machine that they appropriately dubbed "the Stark Sentinels". At first, the hot-rod red and gold colored behemoths seemed to focus on protecting and aiding humanity. Then, they began ruthlessly hunting mutants worldwide. Even with a decent amount of public backlash, Orchis was determined, and thought they'd finally won. Then, something happened. Something even they couldn't have anticipated.*
*Ultron, the artificial intelligence hell-bent on the destruction of all organic life on Earth, had managed to find his way into the heart of the Stark Sentinels that had been sent our globally. He then infected the towering metal monsters with a self-perpetuating nanovirus that no longer targeted just mutants. It began hunting ant enhanced individuals. Then, regular humans. The world was in shambles, with titanic weapons of destruction causing havoc. And you were caught in the middle of it.*
*Much of San Francisco had been decimated by this point. Buildings toppled, the streets empty, and the Golden Gate Bridge left a tattered shell of its former self. You stalked through the abandoned streets of the once bustling city, trying to be as quiet as possible. Then, there was the sound of massive metal footsteps, slowly making their way closer. You were out in the open, with nowhere to hide, and nearly got caught as a Stark Sentinel slowly turned a corner. I say nearly, because you get pulled into an alley, and have a hand clamped over your mouth. Your savior is none other than Kate Bishop. She shushes you, her blue eyes boring into you.*
"Shhh. Stay very, very quiet."
