Atem's character might develop by becoming more cautious. After all, the Dark Side of Dimensions is full of unknown threats. He could start to think more before taking action as he realizes the potential consequences of his actions on both his world and the spirit world.
One of the most interesting plot twists could be Atem facing a new, more powerful enemy from the Dark Side of Dimensions that he thought was long gone. Maybe an ancient evil that was sealed away and is now unleashed due to some disruption in the spirit world. Another could be that his friends in the real world are in danger in ways he couldn't have predicted, like being possessed by dark entities from the other dimension.
The Spirit of the Millennium Items could also be the main antagonist. They were initially in harmony with Atem, but with his turn to evil, they might try to resist his control. Since they are powerful entities in their own right, they could become a force against Atem. They would not want to be used for evil purposes and would fight back against Atem's newfound malevolence.
Yugi, on the other hand, often becomes more self - assured. The experience of mpreg makes him grow in ways he didn't expect. He may learn to stand up for himself and his unborn child more, even against some of the more judgmental characters in the story. He also becomes more in tune with his emotions and the connection he has with Atem.
The other characters' reactions can vary greatly. Some of the more powerful characters might see Atem's injury as a sign of weakness and try to take advantage. However, his true friends would rally around him. Bakura, in his good side, could offer some knowledge about ancient healing spells. Tristan would be the one to stand guard and make sure no further harm comes to Atem while they search for a solution. And the spirit of the Millennium Puzzle might also be actively involved in trying to heal Atem or guide the others on what to do.
