Kat & Ana (カット&アナ Katto & Ana) are young twin ninjas from the WarioWare series. Combining their names will spell Katana, a type of Japanese sword, which strangely enough neither one of the sisters uses. Instead they wield middle-Asian cutlasses.
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 percent of damage. If Kat and Ana both hit, characters that are caught in the X will take 20 damage.
An interesting fact to note is that their voices are ripped directly from the voice samples in WarioWare: Smooth Moves for the Nintendo Wii. Upon being summoned, the duo will either say "Ninja!" or "Katana!".
Twin female ninjas who attend Diamond City Kindergarten. Kat, the older of the two, has pink hair, while the younger Ana has orange hair. Both of the girls are still very young, but they're also very respectful and address their superiors as budding ninjas should. Kat and Ana have a soft spot for living things. Kat loves cats, and Ana is attracted to flowers.

In Super Smash Bros. Ultimate
