...In our world, he did try to destroy us for his own gains, mainly taking the Millennium Puzzle for himself. He wanted to gather all seven of the Items so that he could release a dark god that Mou Hitori no Watashi had sealed away with his death. I don't know if it's the same for your world, but that's how I remember him.

He's a patient and scheming type, from what I remember about him. He tried to our seal away our souls, first inside of figurines, the second time inside of our favorite Duel Monster's cards. He also took over Ryou-chan's body for an entire month to build a diorama of Ancient Egypt so that he could have a final battle with Mou Hitori no Watashi.

Though, between all of those events, there were several months, at least a year or two all together, where he was quiet. It's like we just forgot about him for a time while there was something bigger going on at the time.
