Unexpected crossover requested by @zerolockfan and i’m happy because it’s my son and her son (my former one). A bit heartwarming request because YGO was 17 years of my life. Takahashi-sensei loved super heroes, so I’m sure he would love the Big O. Also when he made the Iron Man manga, he initially wanted Kaiba & Stark having a fight (Marvel declined), so, the request is even funnier lmao
