Captain Cold: Fire and Ice...
Firestorm: An overplayed theme, don't ya think?
Captain Cold: Got a soft spot for the classics.Fire and ice. Two distinct opposites that could never work out together right? Wrong. In the land of fiction its common place to see these two elemental powers in close proximity with each other. They provide a great contrast, either covering for each other's weaknesses or serving as each other's Achilles' Heel. They can be best buddies, reluctant teammates, or mortal enemies. So long as they constantly interact then this trope applies. Subtrope of Fire/Water Juxtaposition and Elemental Rivalry. Given Personality Powers, the characters will often also form a Red Oni, Blue Oni pairing. They'll also contrast in terms of appearance, where the "fire" character will have warmer colors in their design and the "ice" character will have cooler colors. If an electric character is added to this mix, it becomes a Fire/Ice/Lightning dynamic.
Examples:Anime and Manga
- In Dragon Ball GT we have the two brothers Nova Shenron (fire) and Eis Shenron (ice). Despite both being against Goku, they have completely opposite personalities and fighting styles. Nova is the Token Good Teammate of the evil Shenrons and fights fairly, while Eis is an arrogant, twisted villain has no problem using dirty tricks.
- Fairy Tail has boisterous, hot-blooded, red-haired, fire-wielding hero Natsu (Fire) and his serious, level-headed (most of the time), ice-wielding foil Gray (Ice).
- When Magical Girl Lyrical Nanoha INNOCENT finally gave Magical Girl forms to Nanoha's two friends, the Hot-Blooded Arisa and the Shrinking Violet Suzuka, they're revealed to have fire and ice attributes respectively.
- Magical Girl Lyrical Nanoha StrikerS stars two Unison Devices: Reinforce Zwei of the Yagami family and Agito, an ally of the Big Bad. Agito has a built-in affinity for fire magic — a phenomenon known in the series as "Mana Conversion Affinity", of the flame-type in this case,—and while there is no canonical equivalent for ice-based magic, Rein's offensive spells are all cold-based. Needless to say, the two of them rapidly develop an intense rivalry (especially since Rein has a designated master, while Agito technically doesn't), which gets resolved at the end of the season by Agito being adopted into the Yagami family, as well.
- In One Piece two of the Admirals provide this dynamic: the lazy but righteous Aokiji and the ruthless General Ripper Akainu. Aokiji is as forgiving as a Marine can be with the Straw Hats, while Akainu is willing to kill his own men if they even think of deserting during battle. He deeply hates pirates and is the first character to kill a significant pirate in a non-flashback scene. After the timeskip, Aokiji and Akainu get into a fight. Akainu wins, injuring Aokiji in the process.
- Ranma Saotome from Ranma ½ gains this dynamic with Saffron, the Final Boss of the manga. Ranma's Finishing Move is the Hiryu Shoten Ha, a tornado technique that requires the user to have a icy cold Battle Aura to contrast the hot angry aura of the opponent. This is taken to full effect with Saffron who is a humanoid phoenix that specialises in fire attacks. During their battle, Saffron and Ranma also wield the Kinjakan and Gekkaja, Legendary Weapons that generate extreme heat and cold respectively. This allows Ranma to amplify his Hiryu Shoten Ha with the heat of Saffron's literal flames to lethal levels.
- In Rurouni Kenshin: Kenshin and the Kyoto arc Big Bad Shishio Makoto can be considered rivals (both were highly skilled hitokiri during the Bakumatsu period (1853-1868), and now they're enemies. In their final battle, Kenshin's revamp and secret attack summons forth a fierce squall, while Makoto's special attack and power up are announced by roaring flames.
- Shouto Todoroki from My Hero Academia is an odd example. He's a student of UA with the quirk "Half-Cold, Half-Hot", meaning that his right side has the power to create ice (a power he inherited form his mother) while his left side can generate fire (which he received from his father). It's downplayed though considering Shouto doesn't use his father's flame powers until much later.
- Batman and the Outsiders: The villain team Masters of Disaster included members called Heatstroke and Coldsnap. They were lovers whose powers prevented them from even touching. Their motivation for being supervillains was to earn enough money to find a cure for their powers so they could be together.
- Firestorm and Killer Frost (pictured above), might just be the  most well-known examples.
- Killer Frost is a female scientist who got granted ice powers after an accident. She became one of Firestorm's first foes, wanting revenge on the world and especially against Firestorm, before becoming his Arch-Enemy since then. Even though there's two Firestorms out there (Ronnie Raymond and Jason Rusch) and three-four different incarnations of Killer Frost, the Arch-Enemy relationship between them stays intact.
- A strange version of this happens on Crisis on Infinite Earths, where Killer Frost suffers a temporary amnesia and helps the heroes commanded by the Monitor and even falls in love with Firestorm (for the surprise AND dislike of him).

- In X-Men, a notorious rivalry is Iceman, a known member of X-Men, and Pyro, a rogue mutant and member of Brotherhood of Evil Mutants. Both naturally can create and control ice and fire respectively and are considerated as Arch Enemies.
- Speaking of Iceman. Outside of X-books, he has also teamed up with the Human Torch several times. A memorable occasion had them fight Equinox, a villain with fire and ice powers.
- In X-Men, this trope is part of what helps solidify Cyclops' two love interests, Jean Grey and Emma Frost, as diametric opposites of one another. note
- Marvel's Asgardian gods fear Ymir, the most powerful Frost Giant, and Surtur, the fire creature destined to be the Big Bad of Ragnarok. They're also mutual enemies, and would destroy the world if they tried to fight each other (especially if they're in two different locations and rampage their way towards each other). Doctor Strange once helped The Avengers prevent exactly that.
- In All-New X-Men (2016), the team has the time-displaced versions of Iceman and Angel. The later got his wings replaced/upgraded by fire-like constructs after the events of The Black Vortex and can use them to unleash fire storm-like attacks. There's also Oya, who got temperature control powers, meaning she can use fire and ice. Iceman tends to be a bit jealous of her abilities.

Their personalities are complete opposites, with Snart being The Stoic and snarky, while Rory is Hot-Blooded and reckless. To make it even better, if the beams of their guns cross they will end up cancelling each other out. This carries on into Legends of Tomorrow where both serve as the Token Evil Teammates.

- In the Norse Mythology creation myth, Yggdrasil (the Nine Realms that make up the universe) began as two solitary worlds: the fiery realm Muspelheim and the cold, dark world of Nifleheim. When these two realms collided, the melted ice became the primordial giant Ymir, who's body was then used to craft the other seven realms.
- BIONICLE: In most Toa teams, the Toas of Fire and Ice have a Red Oni, Blue Oni dynamic. The Toa of Fire is The Leader and the Toa of Ice is generally The Lancer.

This represents the fact that Ryu and Fou-Lu are two halves of the Yorae Dragon, an immensely powerful god that was split into two beings by the ritual that summoned it.

- Kingdom Hearts gives us Organization XIII, a shadowy cabal of super-powered Nobodies who all draw their powers from different elemental "attributes" (Fire, Water, Earth, Wind, Ice, Lightning, Flower, Moon, Time, Space, Illusion, Light and Nothingness). Appropriately, the resident Fire-user Axel and the resident Ice-user Vexen have polar opposite personalities, with Axel being friendly, carefree, down-to-Earth, irreverent, and Brilliant, but Lazy, and Vexen being cold, arrogant, hardworking and scholarly; and while Axel ultimately does a Heel–Face Turn and joins the heroes, Vexen is one of Xemnas' most loyal servants. Oddly subverted with Axel and the resident Water-user Demyx, who are—if anything—the most similar in personality.

- The Adventure Time episode "Hitman" has the Ice King—a goofy, fun-loving Ineffectual Sympathetic Villain—trying to defend Finn and Jake from the overzealous assassin Scorcher—an eerily silent, ruthlessly efficient killer—when he almost accidentally has them murdered.
