Kat & Ana

"We're not just ninjas- we're also the stars of Mystical Ninja Elementary's upcoming school play!"

- Kat and Ana

Kat and Ana are major human characters in the WarioWare series. They are ninjas and twin sisters who reside at their house in a park of Diamond City. The sisters love nature very much, especially animals and flowers. They attend both the Diamond Kindergarten and the Mystical Ninja Elementary. Kat and Ana first appear in WarioWare, Inc.: Minigame Mania as two of Wario's friends who help him produce microgames.

WarioWare, Inc.: Minigame Mania
Kat and Ana could be seen in the intro of WarioWare, Inc.: Minigame Mania, where they were called by Wario to join his company WarioWare, Inc. and to produce microgames for his upcoming game. Like Wario's other friends in Diamond City, Kat and Ana agree.

In their own story, an evil skeleton spirit called Boneheads appears over the Castle in Diamond City at night. He takes possession of the princess or prince who sleeps under the roof. In order to stop him, Ana appears along with her crew consisting of five other ninjas. They attack the spirit, but he easily defeats all of them with his two long swords. Only Ana could still affect something, but she fails as well. Because she hasn't a chance against Boneheads, she assigns her animal friend Don the Sparrow to carry a letter with the message "Ninja girl! Save me!" to her sister Kat to call for help. After Don leaves, Boneheads also catches Ana who was captivated with a rope then.

Kat resides with Paw the Dog at an unknown place which seemed to be far away from Diamond City. When Don arrives, he drops the letter in front of Kat. Shortly after she reads the message, Kat and Paw head for Diamond City. On their way, they walk across various Japanese looking landscapes.

When Kat and Paw arrive, they already face Boneheads at the entrance of the Castle who floats up to the roof again. Kat and Paw made it through the many floors of the castle and eventually reach the roof where Boneheads awaits them. Kat fought hard, but she couldn't defeat Boneheads with her normal sword. So Paw joined the fight and transformed into a giant sword. With the new weapon, Kat could finally defeat Boneheads after some effective slices. Boneheads degrades bit by bit. The princess or prince is delivered from Boneheads' influence and Kat frees Ana by cutting the rope with that she was captivated. At the end of the adventure, Kat, Ana, and their two animal friends along with the princess or prince being happy could be seen in front of the Castle.

In an unlockable minigame called Jump Forever in WarioWare, Inc.: Minigame Mania, Kat and Ana swing the rope that Wario has to jump. In the unlockable minigame taken from Mario Paint, Fly Swatter, the Bob-omb appearing in the congratulations sequence has been replaced by Kat.

WarioWare, Inc.: Mega Party Game$!
In WarioWare, Inc.: Mega Party Game$!, Kat and Ana performe in a television show called Super Show after 9-Volt's entrance. Under the headline "Karate", the sisters show their ninja skills. However, it isn't known what happened next because Wario's television set burst.

Kat and Ana are two of the ten selectable characters in the multiplayer games in WarioWare, Inc.: Mega Party Game$!.

WarioWare: Twisted!
In WarioWare: Twisted!, Kat and Ana go on a field trip with their kindergarten class on the Diamond Knoll. Their animals, Shadow the Dog and Shuriken the Falcon, came along with them. The teacher instructs the children not to bunk. During the trip, Ana discovers a beautiful flower. While Kat continues to walk, Ana and the two animal buddies stop at the flower. Ana decides to show the flower to her sister and runs after her. However, Kat damages a beehive with a stick when Ana arrived. The bees get angry so the sisters had to escape from the swarm. They abscond into a wooden cabin and rest there for a moment.

However, they aren't alone. Kat and Ana encountered the Diamond Troll. Without that the Troll did something against them, Kat and Ana quickly changed to their ninja outfits and attack him with their swords. Then they charge their swords and were out to send out some kind of sword beam at the Diamond Troll. Shortly before they could attack, Shadow and Shuriken crash right into the cabin and hit the ceiling. Then they fall down on the Diamond Troll and all three are knocked out. Kat and Ana are speechless for a moment.

After these events, Kat and Ana decide to go back, but after they open the door of the cabin, the swarm of bees reappear. All four friends, Kat, Ana, Shadow, and Shuriken, escape from the swarm in front of the sunset.

In Wario-Man's story, the alien Orbulon gave Kat, Ana, Mona, 9-Volt and 18-Volt a flight in his spaceship. All five humans sat on seats behind Orbulon.

WarioWare: Touched!
Ana and Shadow stay in her and Ana's house in WarioWare: Touched!. Ana wanted to eat bananas and so she opens the door to the room where the bananas should lie on a dish. However, she only finds out that the fruit is missing. Shocked by that, Ana hectically searches the fruits in every corner of the room. During this, Shadow notices animal tracks in the house. He advises Ana of the tracks by barking. Ana also saw the tracks now and so she decides to follow the thief and gets the idea to write a note for her sister so that Kat could join later. Then Ana and Shadow get out of the house and run after the thief. Kat joins them along with Shuriken after she reads Ana's note.

They eventually find the thief, who turned out to be a small monkey. First, Kat and Ana are shocked, then they are charmed by the monkey's cute appearance and gave him the name Numchuck. They happily lift the monkey up and down and the little thievery is quickly forgotten.

WarioWare: Smooth Moves
In WarioWare: Smooth Moves, the giant red Elephant Ogre comes to the Diamond Dojo and stood in front of it at night. The concerned Sensei in the Dojo faces the monstrous being who suddenly lets out a piercing shriek. Quickly, the ninja sisters Kat and Ana come to the Dojo's rescue. Ana gets inside the Dojo to reach the Sensei. When she arrives, she saw the Li'l Ogre annoying the Sensei and yanking his hair. Outside, Kat messes with the Elephant Ogre. She activates her clone powers and five Kats seem to appear simultaneously, all of them attacking the giant with their swords. The Elephant Ogre's club and Kat's sword press each other, but then the Li'l Ogre shouts to stop the fight.

It turns out that the Elephant Ogre has just been searching for the Li'l Ogre, probably his child. With the Li'l Ogre on his hand, the Elephant Ogre peaceably left during the sunrise. Kat waves to say goodbye, but she suddenly notices that the actual Li'l Ogre was still there. The being on the Elephant Ogre's hand was actually Ana, whose silhouette looked very much like the Li'l Ogre. She desperately waves with her arms and cries.

Kat and Ana also work as editors of Wario's one-shot newspaper "The Weekly Wario". They write about rumors involving the Form Baton.

WarioWare: Snapped!
In WarioWare: Snapped!, Kat and Ana run the newly opened Wario Park along with Wario, Mona, and Jimmy T..

WarioWare: D.I.Y. Showcase
In WarioWare: D.I.Y. Showcase, Kat and Ana have their very own stage called "Kat and Ana's Sky Patrol". In this stage, they jump off a cliff first only to fly above the sky using yellow capes in a style similar to Cape Mario. They were accompanied by birds (to denote the player's four "chances" for the stage).

Super Smash Bros. Brawl
In Super Smash Bros. Brawl, both Kat and Ana appear as stickers and together on a trophy. In addition, they appear as Assist Trophy characters that fly across the stage and slash players with their swords.

Personality and Powers
Kat and Ana are often depicted of possessing surprising abilities: they have been seen "cloning" themselves, jumping higher than the average human can, and defeating enemies more than twice their size when working as a team. Many of these powers are classic ninja techniques. Despite this, they are also displayed as quite naive (or at least Kat). In WarioWare: Twisted!, Kat disturbs a nest of bees without a thought to the consequences. Kat is the older of the two. Kat acts bossy which sometimes results in making Ana cry, but Kat cares deeply for her. Kat is very fond of animals. Ana is quieter and more careful than her sister. She loves flowers very much. It's unknown how they became friends with Wario.

Microgames
Kat and Ana come with their own set of microgames in all games of the WarioWare series.

For WarioWare, Inc.: Minigame Mania, Kat and Ana created microgames of the Nature genre. All games involve animals or plants or both. WarioWare, Inc.: Mega Party Game$! does also feature Kat and Ana's nature microgames, plus a multiplayer game made by them, Wobbly Bobbly, which involves animals as well, namely turtles.

Since WarioWare: Twisted!, Kat and Ana's microgames involve a particular style of gameplay rather than a specific visual theme. In this game, their set of microgames is called Tap Out and requires to press only.

In WarioWare: Touched!, the name of Kat and Ana's set of microgames is Ninja Scribble and involves scribbling and drawing with the Stylus.

In WarioWare: Smooth Moves, Kat and Ana's set of microgames involves the forms The Remote Control, The Sketch Artist, The Chauffeur, and The Samurai.

Kat and Ana's five microgames in WarioWare: Snapped! require two players to play rather than one. After the end of their stage, photo's of the two players with silly decorations are shown. In Jimmy's stage, a comic strip of the ninja sisters can be shown. In this comic, they have a fighting practice.

In WarioWare: D.I.Y. Showcase, Kat and Ana return to their original role and host a new set of Nature themed microgames again. Unlike the original WarioWare with featured microgames about animals and flowers, the microgames in this set for the game are limited to only animals.
