Super Smash Bros. in the context of Crossover (fiction)

The fighting game genre involves combat between characters, often (but not necessarily limited to) one-on-one battles. The mechanics of combat in fighting games often features blocking, grappling, counter-attacking, and the ability to chain attacks together into "combos". Characters generally engage in hand-to-hand combat, often incorporating martial arts, but some may include weaponry. Battles are usually set in a fixed-size arena along a two-dimensional plane, where characters navigate horizontally by walking or dashing, and vertically by jumping. Some games allow limited movement in 3D space, such as Tekken and Soul Edge while some are set in fully three-dimensional environments without restricting characters' movement, such as Dragon Ball Z: Budokai Tenkaichi, Jump Force, Kill la Kill: If, My Hero: One's Justice, Naruto: Ultimate Ninja Storm, One Piece: Burning Blood and Power Stone; these are sometimes referred to as "3D arena" fighting games.

The fighting game genre is distinctly related to the beat 'em up genre, which pits many computer-controlled enemies against one or more player characters. The first video game to feature fist fighting is Heavyweight Champ (1976), but Karate Champ (1984) actually features the one-on-one fighting game genre instead of a sports game in arcades. Yie Ar Kung-Fu was released later that year with various fighting styles and introduced health meters, and The Way of the Exploding Fist (1985) further popularized the genre on home systems. In 1987, Capcom's Street Fighter introduced special attacks, and in 1991, its highly successful sequel Street Fighter II refined and popularized many genre conventions, including combos. Fighting games subsequently became the preeminent genre for video gaming in the early to mid-1990s, particularly in arcades. This period spawned dozens of other popular fighting games, including franchises like Street Fighter, Mortal Kombat, Super Smash Bros., and Tekken.

Princess Peach is a character in Nintendo's Mario franchise. She was created by Shigeru Miyamoto and introduced in the 1985 original Super Mario Bros. game as Princess Toadstool. She is the princess regnant and head of state of the Mushroom Kingdom, where she resides in her castle along with Toads. Since her debut, she has appeared in the majority of Mario video games as the main female character and the romantic interest of Mario.

As the lead female character in the Super Mario series, Peach's role is typically the damsel in distress who is kidnapped by the main series antagonist, Bowser. In most of the games, her role is to be a captive until she is eventually rescued by Mario. In several multiplayer games of the series, she is a playable character, such as Super Mario 3D World and Super Mario Bros. Wonder. Outside the series, she has appeared as the protagonist and player character of several video games, including Princess Toadstool's Castle Run, Super Princess Peach, and Princess Peach: Showtime! She makes regular appearances as a playable character in Mario spin-offs and other video game series, including Mario Sports games, Mario Kart, Mario Party, Paper Mario, and the fighting game series Super Smash Bros.

Donkey Kong (DK) is a character created by the Japanese game designer Shigeru Miyamoto. A flagship character of the Japanese video game company Nintendo, he is the star of the Donkey Kong franchise and also appears in the Mario franchise. Donkey Kong is a large, powerful gorilla who leads the Kong family of simians. He is stubborn and buffoonish, and attacks using barrels. He wears a red necktie bearing his initials and is accompanied by supporting characters such as his sidekick Diddy Kong, rival Mario, and archenemy King K. Rool.

Donkey Kong debuted as the antagonist of Donkey Kong, a 1981 platform game. He has appeared in many video games, including the original Donkey Kong arcade games, the Donkey Kong Country series of side-scrolling platform games, Mario games such as Mario Kart and Mario Party, and the Super Smash Bros. series of crossover fighting games. The original game characterized Donkey Kong as Mario's rebellious pet; games since Country feature him as a player character protecting his stash of bananas. Some games include Cranky Kong, an alternate, elderly incarnation who breaks the fourth wall. Donkey Kong has appeared in animation, comics, children's books, Super Nintendo World theme park attractions, and merchandise such as Lego construction toys.
