Basic Trope: In a Massive Multiplayer Crossover, a new character is added who is just as important as the others. * Straight: In a Crossover between Evilzulgo and Nigo, heroes Alice and Bob join forces with Sixth Ranger Colin. * Exaggerated: An entire new universe, populated with hundreds of new heroes, villains and creatures, is set up for the Crossover. * The creators make a whole new Five-Man Band, since it worked with Decade, Kyosuke, and Sora. * Justified: The Crossover takes place in a universe or location that both Evilzulgo and Nigo are traveling to in order to trade with the people already living there. Of course one or two of the natives will have major roles. * Inverted: Two series start out as a Crossover, then split apart. Captain Colin appears in both.
