"Collaboration Titles" (クロスシリーズ Kurosu Shirīzu "Cross Series") are pre-constructed decks or packs of cards in collaboration with other non-Buddyfight franchises.

Only cards with the same title's logo (World) can be used with the flag with the same logo. Cards that can be used with all flag, such as [Omni Lord] or "Lost World" cannot be put into the deck unless they have the same logo as the flag's logo.

Card Types for the Cross Series are different from the regular cards. But they characterized to also be of their normal equivalent at the same time regarding effects and game rules.
