- Mother (deceased; kidnapped in the dub)
- Alister (brother)
|Anime debut||Yu-Gi-Oh! episode 150: "Deja Duel! - Part 2"|
Mikey, known in Japan as Miruko, was the younger brother of Alister. In the original Japanese version, Mikey was killed when a tank he boarded was blown up. In the English anime, Mikey was said to have been captured. In either case, the event serves as the basis of Alister's vendetta against Seto Kaiba. Mikey's favorite toy was his Dyna Dude action figure, which his brother holds on to in memory of him.
