This is a superman attack on titan crossover challenge if you want to do it contact me via pm.
Here's the plot the Attack on titan Earth replaces the DC Earth
When Krypton ( this krypton is the Krypton from the 2013 Man of steel live action movie) anyways when it's doomed Jor el sends his infant son Kal el to Earth, where he crash lands in Wall maria.
Kal el crash lands in Wall maria a year after the birth of Eren yeager so Eren is a year old when the infant Kal el crash lands and Eren is thus a year older then Kal el.
Anyways after crashing he ( Kal el) is found by Grisha and Carla yeager and adopted by them, they give him the name Sasuke Yeager.
Anyways in this story Sasuke yeager grows up in wall maria having to hide the powers he gains from Earth's yellow sun, until it's breach where he is forced to reveal his powers however he is too late to save Carla yeager who is eaten before he can kill the Smiling titan.
After Carla's death, like Eren, Sasuke develops an extreme hatred for Titans and assumes his costumed identity of Super man to help the Survey corps combat the titans with his Kryptonian powers!
The story would show Sasuke's adventures as Superman and how his presence and his great destructive power have changed the course of the attack on titan story.
One of the fights I would like to see are superman vs the colossus titan.
The pairing HAS to be Sasuke x Annie
