MCU x Harry Potter x DC
Harry is the MoD after he collects all of the Hallows and defeats Voldemort when he is 15. Due to Dumbledore’s interference, Voldemort and Harry’s souls are merged into one. Harry is branded as a Dark Lord. Harry withdraws all his assets as the Lord Black, Potter, and Prevrell. Luna packs all of her and Teddy’s things in an expanded pouch for transport. They perform a ritual to take them to a new world. Harry holds back to check over everything. As he goes through, Dumbledore bursts through the door with Hermione, Ronald, Ginny, the Order, and some Aurors. Ron and Dumbledore cast Bombarda and Evamsco respectfully, causing the ritual to malfunction a bit.
Peter is on Titan trying to get the Infinite Gauntlet from Thanos. A bit too much pressure is put on the stones. A piece of the Time stone breaks off and the Soul stone breaks off completely and merges with Peter. His soul is not strong enough to hold the powers of an infinite stone so they pull a compatible soul towards Peter to stabilize him. When the Dusting happens, the ritual reaches a crescendo, and they send the hurling toward Harry’s original destination.
Luna and Teddy land safely in Gotham only for some men to try and immediately try to mug them. Before anything can happen, Red Hood stops them. They are directed towards a hotel upon Luna’s request. Luna establishes her and Teddy’s presence but holds off on Harry’s as he has not yet arrived. She buys an apartment and settles in.
The Bats hear rumors of Lazarus Pits being made in Gotham. They stage a break-in only to discover it is being abandoned. They take down everyone but some of the doors are reinforced for them to open. They call in Superman to open them. Most of them were filled with machines labeled as failed attempts and filled with dead bodies. One was noticeably empty, making it clear whoever was in the tank was not a failed attempt. As they got closer to the last room, the criminals who were still awake started to get nervous. Knowing they were probably about to see who the successful attempt was they got into position. Superman bursts down the door and immediately gets hit in to face with a Kryptonite bat.
Peter and Hadrian wake up with the mind and body trying to assimilate with each other(which is easier when one mind has already gone through such processes). Peter starts freaking out as this is very unusual for him. When their mouth opened and tried to take breaths they were filled with water that burned them inside out and left them drowning. They were released from their container and were hit with several tranquilizers before they could process their surroundings. They were given monitored access to the internet, they were able to break through it easily without anyone noticing. During the times they are left alone they try to rein in their anger, which appears as a side effect, and manage to have some form of control so they won’t hurt people. Scientists pick and prod at them for months before the compound is broken into. The door was locked so they had no idea what to expect so they grabbed what looked the strongest, a bat made out of some unfamiliar element. When the door broke they immediately swung.
