It could be Dumbledore in his younger days. Dudley would be really shocked to meet the great wizard when he was still young and full of energy. Dumbledore's wisdom and power would be a complete contrast to what Dudley is used to in his Muggle life.
Maybe he meets a young Snape. Snape's dark and brooding nature would be very different from anyone Dudley has met in his own world. And Snape's complex relationship with Harry's mother could add an interesting layer to Dudley's time - travel experience. Also, the fact that Snape is so deeply involved in the wizarding world's politics and secrets would be mind - boggling for Dudley.
I think it would be really unexpected if Dudley met a house - elf from a long time ago. House - elves have such a unique culture and way of life in the wizarding world. Dudley, coming from a Muggle family, would have no idea about these magical creatures. The house - elf could show Dudley some hidden corners of the wizarding world's past, and Dudley would have to deal with their strange loyalty and magic - based servitude.
One interesting plot idea could be Dudley traveling back in time to when his parents first got married. He could see how his family's attitudes towards magic and the Potters were formed. Another could be him traveling forward in time to see the impact of Harry Potter's actions on the wizarding world and how it indirectly affects the Muggle world he lives in. Maybe he travels to a time when a major wizard - Muggle conflict was about to start and he has to use his new - found knowledge of both worlds to prevent it.
One common theme is redemption. Many fanfictions focus on Dudley changing his ways after years of being a bully. They show him realizing the error of his actions and trying to make amends.
One way is to give Dudley a moment of self - reflection. Maybe he overhears some cruel remarks about himself from other Muggles who are as narrow - minded as his parents. This makes him realize how wrong his family's treatment of Harry has been, and he starts to change. He could then begin to learn about the wizarding world from Harry in secret, slowly becoming more open - minded and kind.
