The Rabbids (ラビッツ, Rabbits; Lapins Crétins (Moronic Rabbits) in French) are recurring characters in Ubisoft's Rayman franchise. Initially antagonists, they eventually were given their own spin-off franchise.
Originally designed as ominous enemy creatures for the canceled 3D platformer Rayman 4, the Rabbids were reworked for the party game known as Rayman Raving Rabbids, as more child-friendly and goofy mascot-like characters. Due in part to their debut game being a launch title for the massively successful Nintendo Wii and their overall marketability, they gained enough popularity to take the focus away from Rayman in later titles, spawn an animated series on Nickelodeon, and eventually overshadow him starting with 2009's Rabbids Go Home. Their most critically-acclaimed appearance is Mario + Rabbids Kingdom Battle, a turn-based strategy game featuring Mario characters, as well as Rabbid versions of characters like Mario, Luigi, Yoshi, Peach, Cranky Kong, Donkey Kong, Wario, and Waluigi. As "anti-mascots" of sorts to the French studio, they have also made cameos in other Ubisoft games including as inanimate toys in Watch Dogs and Far Cry 5; playable characters with weaponry from the Splinter Cell franchise in Teenage Mutant Ninja Turtles: Smash-Up; a cheat code in Assassin's Creed IV: Black Flag; dancers in the Just Dance series (which was in turn an extension of a minigame from Rayman Raving Rabbids: TV Party); and even a brief return to the Rayman franchise as enemies in the mobile game Rayman Adventures.
The Rabbids themselves are depicted as immature and childlike, often pulling sophomoric pranks involving plungers, underwear and toilet paper among other juvenile items. While intelligence level varies on an individual basis, Rabbids are usually moronic and unable to learn from past mistakes. They are known for their distinctive "bwah" screech and singing along to popular pop songs.
As a costume
In the January 16th, 2020 Smash Bros. presentation, the Rabbids were revealed to be a Mii Costume headwear. Similarly to Slime, the ears of the hat bounce when in motion. The reveal trailer references Mario + Rabbids Kingdom Battle, using the title screen music (titled Two Worlds Collide) and showing a Mii Brawler wearing the hat using a Rage Blaster against Ray Gun-wielding Mario, as well as the original Rayman Raving Rabbids games with a plunger from Luigi's tether grab.
