Kat & Ana

Kat & Ana (, Kat & Ana) are recurring characters of the WarioWare series.

Origin
Kat & Ana, whose names are a pun on the word, are young twin ninjas, each with pink and orange hair respectively, who adore living things, specially animals and flowers. They've debuted in the first WarioWare game, and have appeared in nearly every game in the series since then generally as employees of WarioWare, Inc. In each new title, they offer a different short story with a set of microgames to go with it.

Kat & Ana's microgames will focus on either a specific type of controller input, such as drawing on the touch screen like in ', or as having all of them have a specific theme around them, such as all of them being related to nature like in '

They are depicted as kindergarten students, but they're also skilled ninjas and are typically seen fighting large monsters with a variety of ninjutsu skills. Kat, the oldest out of the two, is typically determined and strong willed, and is also the one who tends to take down most of the bad guys they encounter. Ana, the youngest out of the two, is generally more quiet and watchful, while always being happy to accompany Kat in many of their adventures.

Their appearance as Assist Trophies may have been inspired by the attack Kat performs on the in , as while it merely involves Kat and clones of herself she created, the slashes she performs are similar.

As an Assist Trophy
Kat & Ana appear as Assist Trophy characters in Super Smash Bros. Brawl. Kat and Ana use a special dance combination, in which they fly in from various locations off-screen and cross over at the summoner's opponent(s). Any characters that make contact with either Kat or Ana will take 10% damage. If Kat and Ana both hit, characters that are caught in the X will take 20% damage. Kat & Ana are the Assist Trophy parallels to the Pokémon Latias and Latios.

An interesting fact to note is that their voices are ripped directly from the voice samples in WarioWare: Smooth Moves for the Wii. Upon being summoned, the duo will say either "Ninja!" or "Katana!".

As an Assist Trophy
Kat & Ana reappear as Assist Trophy characters, filling the same role they played in the previous game. They now sport their design from Game & Wario.

As a background character
Ana by herself can appear as two different stickers decorating Gamer. One of them appears on the right side of the main platform, while the other appears on a large solid platform that can randomly appear in the middle of the stage.

In Smash Tour
Kat & Ana's trophy is one of the red items in Smash Tour. When it is used before a battle, the user will automatically tech all collisions with walls and ceilings for the duration of that battle.

In Super Smash Bros. Ultimate
Although Kat & Ana no longer appear as an Assist Trophy, the two Ana stickers still appear on Gamer, and they also appear together as a master spirit.

As a background character
The two Ana stickers appear on the same spots as they were before, now using artwork from WarioWare Gold.

Spirit
Kat & Ana appear as a master spirit. Their dojo is located in the wasteland section of the Light Realm in World of Light.

Their spirit battle has two s, a pink and orange one respectively, as puppet fighters on Suzaku Castle, with only throwable items spawning and the enemies constantly jumping. The following is a list of quotes that Kat & Ana can say when a player visits their dojo.
