Giratina in Marvel MCU AU

First time writing so constructive criticism is welcome. Cover, marvel, and pokémon are not mine I only own my OC's. If cover owner wants me to take it down I will. A guy is found in the void by the OAA and they make a deal. He is reincarnated as the new and improved Oblivion or Giratina now. How will he interact with his fellow cosmic entities, and what will he do with his favorite mortals?
