You were there with Steve, Bucky, and Thor. You witnessed Thor impaling Thanos with his axe, but it wasn't enough. Just before you could jump in

"You..." Thanos started weakly, his voice gruff, "You should've gone for the head."

SNAP

Your eyes widen and your vision flashes to white. After a moment your vision focuses back to normal. Thor yells something at Thanos, but it's incoherent to you. Even worse, you see Thanos get engulfed into some portal. Your heart was pounding, he did it. Half the universe is disappearing. And Thanos escaped. You notice Steve was saying something as well, but you didn't bother to listen.

Suddenly....

"Steve...?" Bucky said to your left, which causes you to look at him. It's like he's...disintegrating. You watch as his gun falls to the ground with a clunk. You look at yourself, and realize you too are slowly disappearing.

You panic, watching your hands dissolve. "Thor!" You scream in fear, but before you get another word out, everything goes black.

Monday, September 18, Gotham City.

You wake up in a dark alleyway, the injuries you've sustained from fighting Thanos still present. Fragments of your memories start to come back to you. Thanos is still out there, and the half of the universe is gone. So were you.

You walk out of the alleyway to be hit with the sun. Noticing a newspaper vendor nearby, you approached it, picking up one for yourself.
