▪Kaiba duels Atem in the afterlife and loses, but Atem lets Kaiba know how strong of an opponent he was. He stays a while longer to resolve any issues between them.
▪Before Kaiba leaves the afterlife, Atem asks him to look after Yugi for him.
▪During Kaiba’s absence, Mokuba handles the company pretty well, but had a breakdown at some point from bottling up his emotions. Isono was there to help him the whole time.
▪Yugi checks up on Mokuba whenever he can to see how he’s holding up. This helps them form a almost-brotherly-type bond. Although Yugi has had some mother hen moments.
▪Upon Kaiba’s return, everyone is relieved but a bit upset at his sudden departure. It takes Kaiba a while to apologize and be forgiven, but everything returns to normal.
▪Joey becomes a pro-duelist and usually places in the quarter or semi-finals in tournaments. He also has a part-time job to be financially stable.
▪Tristan works at his father’s factory, but moved up in rank over the years. Around the time of GX, he becomes the manager. His factory actually manufactures the duel disks for KaibaCorp.
▪Téa studied at and graduated from Julliard and becomes a professional dancer for a few years. Afterwards she becomes a choreographer.
▪Yugi does become a successful game creator, most notably for Spherium. Spherium also began the official partnership between him and Kaiba. He still helps out his grandfather at the game shop.
▪Around the age of 20-21, Kaiba finally wins against Yugi. Of course, that doesn’t last too long. So for the next few years, the King of Games title goes back and forth between the two. By the time GX starts, Yugi is the current champion.

I like these but you left off someone important… What about Ryou?
