王國之心II
Before being introduced in "Kingdom Hearts Birth by Sleep", Ventus made cameos in the secret endings of "Kingdom Hearts II" and its re-release, "Kingdom Hearts II Final Mix", which depict him and his friends Terra and Aqua battling Master Xehanort and Vanitas. Ventus is also shown in a cameo in "Kingdom Hearts 358/2 Days" when Xion, a replica of Roxas, appears as Ventus while fighting Xigbar from Organization XIII. Ventus is also constantly referenced by Xigbar in "Kingdom Hearts II" and "358/2 Days" while Xemnas, the Nobody of Xehanort, searches for him in Castle Oblivion.
