Crossover Combo Villain

Go To

When one creates a crossover, the issue of who the villain of the event should be comes up. Should it be a villain from one of the involved properties, a team-up, or something new altogether?

Sometimes, the best solution is to combine stuff from the crossing over universes to make a villain appropriate to both. Thus, the Crossover Combo Villain. It could be a character from one work utilizing an element from the other, a literal fusion of characters to create a single new antagonist, or something else entirely— so long as it combines elements from the involved works into a single antagonist, it qualifies.

Note that just having an original villain for a crossover doesn't count, they have to combine elements from the works crossing over in some way.

Contrast Crossover Villain-in-Chief, which sees an already established villain rise to lead the forces of evil.

  • Flashpoint 2: Advent Solaris turns Mephiles the Dark into one, as not only is he a Sonic character but he also is revealed later on to be a union of Darkseid and Trigon.
  • The Big Bad of the Gravity Falls/Soul Eater crossover Gravity Soul is a fusion of Bill Cipher and Asura after they come Back from the Dead.

  • An in-universe example happens in Wreck-It Ralph, where the Big Bad Turbo jumped from his racing game Turbo Time into the kart racer Sugar Rush and made himself into its ruler, King Candy. Later, when the Cy-Bugs from the shooter Hero's Duty invade, Turbo gets eaten and absorbed by them, his final form being a mashup of his Turbo and King Candy personas with a Cy-Bug.

  • The titular protagonist of Kamen Rider Decade is an odd heroic inversion of the trope, acting as a villain to all previous Riders with the ability to transform into them.
  • In Power Rangers: "Reinforcements from the Future", the two-part crossover between Time Force and Wild Force, there are the "Mut-Orgs" - a group of surviving Orgs who were unsealed by Ransik in the year 3000 and used his mutant DNA to construct new, more powerful bodies for themselves.

  • Transformers:
    • Generation One Starscream has become this trope thrice:
    • Transformers vs. the Terminator: At the end of the miniseries, Skynet becomes this after the Terminator it sent back in time succeeded in his missions to ensure its creation and cripple the Transformers. Whereas the original timeline was an Evil Versus Evil war between Skynet and the Decepticons, the new timeline has mankind reverse-engineer the corpse of Megatron, whom the Terminator killed in the past, into Skynet.

    Video Games 
  • In Mario + Rabbids Kingdom Battle, many bosses are Raving Rabbids mixed with something from the Super Mario Bros. franchise due to a Merging Machine mishap. Pictured above are two of the final opponents, Bwario and Bwaluigi, a pair of Rabbids dressed as Wario and Waluigi.
  • Marvel vs. Capcom: Infinite:
  • Mortal Kombat vs. DC Universe features Dark Kahn, a fusion of Darkseid and Shao Kahn.
  • Frost's "The Cyber Initiative" Fatality in Mortal Kombat 11 has her freeze her opponent's body, shatter it, and put their brain into a Cyber Lin Kuei. One such opponent is the T-800.
  • Super Robot Wars is heavy on this, given that most titles feature a Big Bad Ensemble. The final boss is usually either a powerful alien, a godlike entity, or a particularly resourceful human whose robot uses all of the combined technology from the shows involved in the game.
    • Games featuring the Devil Gundam often replace its gigantic final form by having it fuse with a different artificial satellite from another series (such as the Axis, producing the "Devil Axis"). Original Generation 2 has the Einst Regisseur pull the same trick, fusing with the White Star into a new unique form.
    • Euzeth Gozzo is especially fond of this trope, using it in two of his three appearances as the lead villain across the franchise's history. His concoctions invariably lead to a machine that looks like himself as an Ultraman.
