Editing Mai Valentine (section)

=== Legendary Heroes ===
Shortly after Duelist Kingdom, Mai Valentine was invited by The Big 5 to test a newly reprogrammed version of the Virtual Game built by [[Seto Kaiba]]. During this time, Yugi, Joey, and [[Mokuba Kaiba|Mokuba]] were searching for Kaiba. Along the way, Joey was forced to Duel Mai. Upon realizing her opponent was Joey (as both were masked), Mai joined the search for Kaiba.

During their journey, they faced numerous challenges: being attacked by a "Sand Stone" monster, getting trapped in a maze, fighting an army of Winged Beasts and Insect monsters, and ultimately battling the Big Five's "Mythic Dragon." Each of the Legendary Heroes needed to summon a Dragon-type monster to defeat the Big 5. Mai summoned her "Harpie's Pet Dragon" and sacrificed it to keep Yugi's "Black Luster Soldier" on the field, losing all her Life Points in the process. She was later revived by the "Mystical Elf."
