Fusion Dance / Live-Action TV

---

• Firestorm appears in the Arrowverse first as the fusion of Martin Stein and Ronnie Raymond on The Flash (2014) then as Stein and Jefferson Jackson on Legends of Tomorrow. An evil Earth-2 version, Deathstorm, also appears in one Flash episode.
• Buffy the Vampire Slayer:
  • In the climax of Season 4, the Slayer temporarily merges (mentally) with her three sidekicks to acquire Willow's magical talent, Giles's obscure knowledge, and Xander's heart. (If you're thinking so what, go watch any number of episodes where he demonstrates non-powered bravery.)
  • The First Evil does one with Caleb.
• A dark example in Doctor Who happens in "New Earth", since Lady Cassandra, after being reduced to a Brain in a Jar that controls a piece of her skin becomes interested in getting a younger body and ends up getting her hands in a body swap device called a psychograft. She uses this to possess the body of Rose Tyler at first and while her personality remains mostly the same afterwards, she does gets influenced by Rose emotionally to some extend, gaining Rose's crush on the Doctor and ends up giving him a passionate kiss because of it. The fusion effects seem to be temporally as well, since It's explained that the mind and personality of the user of the psychograft eventually replaces the original personality of the host over time.
• Dollhouse: Echo and Alpha are both prime examples of this; to a lesser extent, other dolls are as well. Even the individual imprints are, since they are usually composites of different people made into one personality.
• In Earth: Final Conflict, the Taelons and Jardians used to be one species, the Atavus, but millions of years ago they split into two. At one point Da'an tries to merge his energy with a Jardian. It works for about a minute, before the fusion splits apart. Da'an survives but the Jardian is killed. Later, six Taleons and six Jaridians attempt the same thing, this time with the aid of special chambers. We do not learn what became of them after this.
• Kamen Rider:
  • Kamen Rider Den-O:
    • Ryotaro (and to a lesser extent, Yuuto) contract with various heroic Imagin who possess their partners. This results in the possessed human's body being controlled by the Imagin and speaking with his voice while gaining some outward physical changes (like glowing eyes and a lock of hair, both in the Imagin's personal color). This also extends to their Rider forms, where an Imagin taking control causes the Rider suit to change armor, weapons, and abilities based on the Imagin's personality. Ultimately, possession is a Power Booster for the Imagin, as having a physical body gives them advantages but their host has little to no control.
    • Late in the series, Den-O Climax Form is a case of Five Beings, One Body; as Ryotaro is possessed by all four of his partner Imagin at once and they share control of his body. Super Climax Form from The Onigashima Warship escalates this as a case of Six Beings, One Body; as Ryotaro is not only possessed by all four of his partner Imagin, but also Sieg, at once; and all five still share control of his body.
  • Kamen Rider Kiva does the Power Booster example. Kiva gains alternate forms by using his allies as weapons and adopting some of their traits.
  • Kamen Rider Double uses Two Beings, One Body, as when Shotaro and Philip transform into Double, Philip passes out and his consciousness transfers to Shotaro's body, where he controls the right half and Shotaro maintains control of the left. Double himself speaks with the voices of his individual parts in unison, though both halves can also engage in conversation with each other. Mid-Season Upgrade FangJoker reverses the dynamic, using Phillip's body and Shotaro's mind, while for Double's Super Mode CycloneJokerXtreme, the Transformation Trinket actually absorbs Phillip's body and merges it with Shotaro for a true Fusion Dance.
  • Kamen Rider Build: In the movie Be The One Sento/Build and Ryuga/Cross-Z fuse into Cross-ZBuild, which is Two Beings, One Body very similar to Double.
  • Kamen Rider Zi-O: Sougo fuses with Geiz and Woz when using his Trinity form. It usually functions as a Power Booster for Sougo, as he gets the powers and weapons of the others while they can talk to him in his head; but it's also a Switcher (at least mentally) since either Geiz or Woz can also take control of their shared body from Sougo if they choose.
  • In Kamen Rider Zero-One's post-series movies, the four androids who make up MetsubouJinrai merge their programming into a new body and become Kamen Rider MetsubouJinrai. It ends up being an extreme Composite, as the Mental Fusion destroys all four original personalities and it becomes an insane Omnicidal Maniac, seemingly permanently.
  • Kamen Rider Revice has the Igarashi siblings fight with their inner demons, and all three receive a Super Mode where they merge with their demon and combine their powers (with the demon acting as a Power Booster for the human). The tie-in movie also sees the three merge with each other into Kamen Rider Igarashi, a Composite fusion.
  • Kamen Rider Gotchard features alchemical Mons called Chemies that can be used for various fusions (seemingly Power Boosters since the humans appear to be in total control, but physically Composites):
    • Gotchard himself uses his Transformation Trinket to fuse with two Chemies at once, able to become either a warrior with characteristics of both, or a flat-out mashup of the two Chemies — for instance, he can combine with a grasshopper and a steam train to become a steam-powered grasshopper, or a pirate and a sports car to become a wheeled pirate ship.
    • If a Chemy is exposed to a hateful, malicious human, then it will unwillingly be drawn to them and they'll merge into a dangerous Malgam monster. However, it's shown at least once that a Chemy can also voluntarily share their power in a sort of reverse-Malgam fusion: when a wrestler Chemy befriended a retired fighter, it merged with him and brought him back to his prime, allowing him to aid Gotchard and fulfill his wish to get back in the ring at least once.
• Mystery Science Theater 3000 "Mitchell":
  Dr. Forrester: "Oh, Frank, look! Remember? The double butt graft! My science project from Evil-O's. I grafted the butt of a dog onto the butt of a cat. Sure, they all laughed...."
• Power Rangers
  • Power Rangers in Space: Darkonda can force Ecliptor (and possibly others, though we've never seen it) to fuse with him, becoming Darkliptor. Darkliptor has the design and weapons of both, but the voice and will of Darkonda only. (Ecliptor has been able to force a separation, but not control the combined form.) Another case of a Power Booster that looks like a Composite.
  • Jack, Nick and Mack ALL gained their "battlized" forms by fusing with allies: the Robot Buddy R.I.C, the dragon Fireheart and the Sentinel Knight. Sentinel could talk (through a giant face on the armor; it's as unnerving as it sounds) but it's not clear if he could take the driver's seat. Again, Power Booster disguised as Composite.
• Its companion series Isis (AKA The Secrets of Isis) features Andrea Thomas transforming into the Egyptian goddess Isis.
• The live-action series Shazam! features the Billy Batson/Captain Marvel Switcher.
• In one episode of Star Trek: Voyager, Neelix and Tuvok are accidentally merged together. The new hybrid character "Tuvix" (played by a new actor) didn't want to be separated, and Captain Janeway did it by force. Tuvix had several of the positive traits of both component beings, including a sense of humor (which Tuvok didn't have) and edible cooking (Neelix was a decent cook, but all the dishes he knew how to prepare were radically different from Alpha Quadrant tastes).
  • The Original Series episode "Metamorphosis" resolves with the Energy Being called the Companion merging with a lonely dying woman named Nancy Hedford, thus saving her life and giving the Companion the physical body she needs to properly court Zeffram Cochrane, whom she loves (and giving Nancy Hedford a chance to finally experience love). The resulting personality is a Composite of the Companion and Nancy.
• In Season Two of Star Trek: Picard, Agnes Jurati and the Borg Queen initially enter into a Two Beings, One Body situation that gradually evolves into a composite entity by way of a few episodes of Grand Theft Me.
• Supernatural: As revealed in season 15, God and Amara have been separated since the birth of the universe, but in order to dismantle reality and do a "hard reset" they have to pool their powers and remerge into a single deity. When they do, they sport multi-colored eyes, one pitch black and one pure light.
• This actually happens a lot in many seasons of Super Sentai, usually with villains and monsters, though sometimes the heroes ustilize this too.
  • In The Movie of J.A.K.Q. Dengekitai, the Crime Big Four merge to form the Big Four Robo, though it bears little resemblance to any of the four.
  • Gosei Sentai Dairanger features the Gorma Four Deva Kings, whose combined form was used on Mighty Morphin' Power Rangers as the generic monster Four Head. Later, in The Movie of the Series, which went unadapted, The Duke Of Cards used his magic playing cards to merge himself and four other revived monsters into Great King Ojaru.
  • Chouriki Sentai Ohranger had Yokai Onbu Obake, and Machine Beast Bara Gear, who merged together to form “Onbu-Gear”. Used for Impursonator and Cog Changer on Power Rangers Zeo, who formed “Cog-Impursonator”.
  • Denji Sentai Megaranger had Giga-Guirail, the combined form of Guirail and Yugande, the Japanese counterparts of the above Darkonda and Ecliptor. In the same series, the Soldiers Kunekune can combine into the King Kunekune, which was used on Power Rangers in Space for the Craterites and Craterite Conglomerate, respectively.
  • In Seijuu Sentai Gingaman, Spectral Empress Iliess can combine with the souls of her fallen Majin, becoming the monstrous Evil Empress Iliess. Adapted on Power Rangers Lost Galaxy as Hexuba’s second form.
  • In Kyukyu Sentai Gogo V, the three Psyma Beast siblings Zoodo, Jiin, and Guuru, who were used on Power Rangers Lightspeed Rescue as Demonite, Falkar, and Thunderon, were combined into the three faced Chimera, which was adapted as the monster Troika.
  • The Movie of Mirai Sentai Timeranger included the return of the previous series Spell Master Pierre, who merged with unused monster Killer Boxer Boribaru, forming the gigantic Pierrebori which was used on Power Rangers Time Force as the unrelated monster Quarganon.
  • Hyakujuu Sentai Gaoranger; After being reduced to puddles of goo, the three Highness Duke Orgs are combined into the Ultimate Org Senki, who possesses elements of all their bodies. Used on Power Rangers Wild Force as the final form of Master Org.
  • The Movie of Ninpuu Sentai Hurricaneger had the two Space Ninsaru, who could combine into the giant Ashurasaru. The series proper also had the Ninja Wolf Beasts Fangarou, who could combine to form the Giant Beast Fangerus, which was used on Power Rangers Ninja Storm as the Wolfblades.
  • Towards the finale of Bakuryuu Sentai Abaranger, two of the main villains, Visionary Messenger Voffa and Creative Messenger Mikela are merged into the monster Dezumovoorla, the temporary host of their master Wicked Life God Dezumozorlya. Used on Power Rangers: Dino Thunder as an unnamed monster of the week.
  • In Kaizoku Sentai Gokaiger, when Gai can't decide which of Go-onger's Sixth Rangers he wants to transform into, the keys combine into one that has the power of both Go-on Wings. A Composite type, since the suit is half-and-half ala Double (he even riffs on their catchphrase), and Gai has two Rocket Daggers available.
  • He does it again later with the GokaiRed and GokaiGreen keys, in a one-time fusion to create GokaiChristmas.
    • And then there's his Super Mode, gained by merging all the Sixth Ranger keys into the Golden Anchor Key.
    • An Omake has Gai and Marvelous fuse together into a hilarious mishmash of each other, which passes down to their initial transformation, which utterly confuses the announcer upon seeing the silver jacket of GokaiSilver with the red helmet and boots of GokaiRed
    • The Movie of the series featured the return of nearly every single Mook that had appeared in the series up to that point, fusing together into the Combined Combatant.
  • Kaitou Sentai Lupinranger VS Keisatsu Sentai Patranger had this as a regular for the Patrangers. To be specific, all three members fused into one body when using Good Striker as the key for the fusion. Due to not being assign individual Super Form like their counterparts, Lupinranger, this becomes their regular form when doing finisher. The Lupinrangers also had one but as a summer movie exclusive, which is Lupin Tri-Colour.
• On Teen Wolf, the twin brother Alphas Aiden and Ethan can do this to become a big super-Alpha.
• The Ultra Series often uses a Switcher-type for its heroes, having an alien Ultra-being bond with a (typically recently dead) human. There have also been composite types.
  • Ultraman Ace actually has a double example, with Ace bonding with two humans, Seiji Hokuto and Yuko Minami, who would then fuse together to give him control. This is dropped after about halfway through the series when Yuko Minami leaves Earth to return to her true home on the Moon.
  • Ultraman Taro can fuse with the other "Ultra Brothers" Ultraman, Zoffy, Seven, Jack, and Ace to form Super Ultraman Taro, a Power Booster. While his appearance doesn't change, it dramatically increases his power and allows him to fuse their powers into the Cosmo Miracle Beam.
  • Ultraman Cosmos and Ultraman Justice fuse into Ultraman Legend in The Movie Ultraman Cosmos vs. Ultraman Justice: The Final Battle. It's hinted that Legend is their original identity and that Cosmos and Justice are a Literal Split Personality.
  • Ultraman Mebius:
    • In the Grand Finale, Mebius, Ultraman Hikari, and GUYS merge into Mebius Phoenix Brave mode, thanks to The Power of Friendship between Mebius and his friends, and use the power of this fusion, along with Zoffy's and GUYS Light Beam Satellite to end the threat of Alien Empera once and for all.
    • Mebius can also fuse with the six Ultra Brothers to become Infinity mode, which is used in the Ultraman Mebius and the Ultra Brothers movie to battle the gargantuan U-Killersaurus. This is more of a Power Booster.
  • Ultraman Zero, Ultraman Dyna, and the before-mentioned Cosmos fuse into Ultraman Saga in the movie of the same name in order to battle the kaiju Hyper Zetton.
  • Ultraman Ginga S:
    • Ginga can fuse with his mentor Taro (who takes the form of an Upgrade Artifact in this series) to activate a Ginga Strium Super Mode. Ginga Strium actually has more powers than just the two, as Taro's Ultra Brother comrades have shared their light with him and Ginga Strium can use their techniques, but these aren't a full fusion.
    • In the Ginga S movie, Ginga and Victory can become Ultraman Ginga Victory, though it required some training from Ultraman Zero to achieve it. Like with Ginga Strium, Ginga Victory has additional abilities shared from the Heisei-era Ultramen as well.
  • Ultraman Orb, Ultraman Geed, and Ultraman Z look like they're composites of themselves and two to three other Ultramen, but the trope is averted since they're really just Power Copying. Though forms based on the evil Ultraman Belial do tend to have a bit of his personality seep through.
  • In Ultraman R/B, Ultramen Rosso and Blu can merge into Ultraman Ruebe. In The Movie, they take it a step further by also merging with their little sister Ultrawoman Grigio, becoming Ultraman Gruebe.
  • Ultraman Taiga enters his Tri-Strium Super Mode by fusing with his friends, Ultramen Titas and Fuma. Ultraman Taiga The Movie: New Generation Climax takes it further by fusing all six "New Generation"-era Ultramen to date in their Super Modes into Ultraman Reiga — and three of those are already fusions (Ginga Victory, Gruebe, and Taiga Tri-Strium), which means it's actually composed of eleven Ultras.
  • There are a number of kaiju fusions as well:
    • Orb, Geed, and Z all had villains who had dark counterparts of the heroes' Transformation Trinket, and used its multi-part Power Copying to create fused kaiju like Zeppandon (Zetton and Pandon), Skull Gomora (Gomora and Red King), Thunder Killer (Eleking and Ace Killer), and Pedanium Zetton (Zetton and King Joe).
    • Five King appeared in Ultraman Ginga S as a fusion of Golza, Melba, Reicubas, Gan-Q, and Super C.O.V. Other fusions in this "line" appeared later, as Ultraman Z saw it appear first as Tri-King (with just Golza, Melba, and Super C.O.V.) before being upgraded to Five; and then Ultraman Trigger: New Generation Tiga had just Golza and Melba fused into Golba.
