Crossover Combo Villain

Were you expecting a unique boss? TOO BAD, BWALUIGI TIME!

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.

Examples:

  • The Stern Regisseur encounter splits the difference between its portrayals in OG2 (where it is a fusion between the Einst commander Neue Regisseur and the OG1 villains' space station White Star) and the OGs remake (where it is simply the commander's normal appearance and the station remains unscathed) - its design is changed from a giant spherical Neue Regisseur to simply Neue Regisseur attached to the White Star by a stalk, allowing it to be destroyed while leaving the station largely intact.
  • The Einst also manage to corrupt secondary antagonist Wendolo of the Inspectors into a Mole for their cause, granting his mecha a more organic form - something which doesn't occur in either videogame version of the story.

  • Mirai Sentai Timeranger vs. GoGoFive: The final enemy is BoriPierre, a Fusion Dance between the film's Timeranger-based Monster of the Week Boribaru and Kyūkyū Sentai GoGoV supporting villain Pierre.
  • By accident or design, the name scheme developed for the monsters of the week in Juken Sentai Gekiranger gave rise to one for the crossover movie Engine Sentai Go-onger vs. Gekiranger. A kung-fu fighting cyborg turtle, fitting both the rival martial arts school of Gekiranger's villains and the cyborg/mechanical theme of Go-Onger's. All because the already developed naming theme ^note Rin Juu Ken fighters having their names be their animal style in Japanese but with the last syllable first turns Kame^note Japanese for turtle into Meka.
  • In commemoration of the franchise's 45th anniversary, Kikai Sentai Zenkaiger the Movie: Red Fight! All Sentai Great Assemble!! has Super Warumono World, whose body is composed of elements from all 44 of the previous Sentai Big Bad.
  • Every Monster of the Week in Avataro Sentai Donbrothers is an homage to a previous Super Sentai series. With every series mandated to have a crossover film with its immediate predecessor, the monster themed after Donbrothers' predecessor Zenkaiger was naturally reserved for that film.

  • The villains in Kamen Rider × Super Sentai: Super Hero Taisen have the Combining Mecha Big Machine, formed from the flagships of the antagonist groups of Kaizoku Sentai Gokaiger and Kamen Rider BLACK RX.

It also has a Crossover Combo Hero, as for their finishing move on the Big Bad, Saber and Zenkaizer perform a Fusion Dance into an one-off form for Saber with Zenkaizer's color scheme.

Live-Action TV

• 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.
  • When Decade's dimension hopping adventures landed him in the world of Samurai Sentai Shinkenger, the main antagonist of the story turned out to be a Shinkenger Monster of the Week that stole the Diendriver, becoming a monstrous Kamen Rider. This power up also disabled the standard Sentai monster ability to turn into a giant, so Decade wouldn't be left behind by the obligatory giant robot fight.
• Similarly, Kamen Rider Zi-O features the titular Rider's evil future self, Ohma Zi-O, as the nigh-omnipotent ruler of the world, who's defeated every other Kamen Rider and has complete mastery of all of their powers. He's so powerful that actually defeating him in battle isn't even entertained as an option, with the overall goal of the season instead being to prevent him from existing in the first place.
• In Power Rangers: "Reinforcements from the Future", the two-part crossover between Time Force and Wild Force, has 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.

Tabletop Games

• Worlds Collide: Battle for the Multiverse, a Crossover between Renegade Game Studios's Essence20 Hasbro Tabletop RPGs, features Lord MindWaveZ, a fusion between Shockwave, Doctor Mindbender, and Lord Zedd created when the three of them simultaneously tapped into a network of multiversal energy.

Toys

• Transformers:
  • Generation One Starscream has become this trope thrice:
    • In the prose short stories accompanying the Transformers × Neon Genesis Evangelion toys, the Autobots must team up with NERV to stop "Angelscream", an Angel possessed by his ghost.
    • In the Mazinger Z Versus Transformers manga, he absorbs photon power and Mazinger Z's spare parts at the climax, becoming "Mazinscream".
    • Though Starscream becoming an undead ghost is a pre-existing recurring concept in Transformers fiction dating back to The Transformers, Transformers/Ghostbusters employing it is this to give Ghostbusters (IDW Comics) a valid reason to get tangled in the affairs of giant alien robots from outer space.
  • 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.
• Marvel vs. Capcom: Infinite: Ultron and Sigma combine to form Ultron-Sigma.
• Mortal Kombat vs. DC Universe features Dark Kahn, a fusion of Darkseid and Shao Kahn.
• 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 Einsts' leader Neue Regisseur pull a similar trick to the Devil Gundam, fusing with the derelict White Star (the villains' orbital battlestation from Original Generation 1) to achieve a new One-Winged Angel form called "Stern Regisseur". This is however Retconned by Original Generations, where the encounter uses the Stern Regisseur design from the start and there's no indication of it fusing with anything.
  • Super Hero Sakusen: Euzeth Gozzo gathers data from the heroes to create "Choujin Zest", a Humongous Mecha resembling a winged Ultraman version of himself which serves as the Final Boss.
  • 2nd Super Robot Wars Original Generation:
    • Euzeth Gozzo (who can remember past iterations of the universe) combines elements of his previous plans by collecting various defeated enemy units, feeding their data into the Mechanical Abomination AI-1, then having it simultaneously absorb the angelic Nashim Gan Eden, a Cross Gate, and Ing (see below) to create the blasphemous "Adamatron",^note from "Adam-Metatron" which resembles a giant limbless Fallen Angel with Euzeth's mask as its face.
    • Player Character Ing is revealed to be not just one of the augmented Machinery Children, but one created from the DNA of the Alpha continuity version of Euzeth's favoured pawn Ingram Plissken (Machinery Children do exist in the Alpha setting, but only in a Bad Future).
  • Super Robot Wars EX: The Final Boss of Masaki's route is the "Super Masouki" Duraxyll - a Masouki (a spirit-powered mecha from the Magical Land of La Gias) which incorporates data from various Gundams into its design, including a Chest Blaster similar to the ZZ Gundam's High Mega Cannon, and remote weapons similar to the Nu Gundam's fin funnels. When the Duraxyll reappears in the Original Generation continuity it uses data from the Huckebein series instead, resulting in a slightly different appearance with a less Gundam-like head.
  • Mazinkaiser debuted in Super Robot Wars F Final as a Crossover Combo Hero created when Mazinger Z was exposed to large quantities of Getter Rays; later appearances remove this and make it simply a Super Prototype. Similarly, Super Robot Wars V introduces Mazin Emperor G as an upgraded Great Mazinger fuelled by both Photon Power and Getter Rays, designed as a countermeasure in case either of the two ever spawned something out of humanity's control (making it a Suspiciously Similar Substitute for Great Mazinkaiser from Shin Mazinger ZERO).

It’s rampage doesn’t just include their shows; other then-current Cartoon Network characters are shown to have been assimilated at some point, popping out of the Reaper only briefly when it’s defeated.
• The second and third The Jimmy Timmy Power Hour both include these, the former having a fusion of Professor Calamitous and Jorgen von Strangle, and the latter featuring Shirley, a villain custom-made by Jimmy and Timmy to challenge them.

Multi-Media/Other
