Kat & Ana

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

- Kat & Ana

Kat & Ana are major human characters in the WarioWare series. They are ninja twin sisters who attend Diamond City Kindergarten and adore nature, especially animals and flowers. Their house is located in a park in Diamond City. Their names are a pun on the word "", a type of Japanese samurai sword. Kat & Ana debut in WarioWare, Inc.: Mega Microgame$! as two of Wario's friends who help him produce microgames.

Background
Kat & Ana share information about themselves and their family in their diary at the official WarioWare, Inc.: Mega Microgame$ Japanese website. They come from a family of ninjas, named Iga Clan, which greatly inspires them to practice ninjutsu since childhood and become ninjas themselves when they grow up. Kat & Ana's father left his parents' house when he was a kindergartner to seclude himself in the mountains and develop his self-discipline. Kat & Ana planned to do the same, but abandoned the idea after playing a game of living by themselves for a while. However, Kat still expresses her resolve to go through this training.

WarioWare, Inc.: Mega Microgame$!
Kat & Ana are introduced in the opening cutscene of WarioWare, Inc.: Mega Microgame$!, in which Wario invites them and other friends of his to join his company WarioWare, Inc. as game developers.

In Kat & Ana's story, a villainous skeleton spirit named Boneheads appears over the Castle in Diamond City at night. He takes possession of the prince or princess who sleeps under the roof. 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 lengthy swords. Only she can still affect something, but she fails as well. Because Ana hasn't a chance against Boneheads, she assigns her animal companion, Don the Sparrow to carry a letter with the message "Ninja girl! Save me!" to her sister Kat to call for help. After he flies off, Boneheads also captures Ana who is captivated with a rope.

Kat resides with Paw the Dog at an unknown place in which seems to be far away from Diamond City. When Don the Sparrow arrives, he drops the letter in front of her. Shortly after, Kat reads the message and heads for Diamond City with her faithful canine companion. On their way, they came across various Japanese landscapes.

When Kat and Paw the Dog arrive, they already face Boneheads at the entrance of the Castle who floats up to the roof again. Kat and Paw the Dog make it through the many floors of the Castle and eventually reach the roof where Boneheads awaits them. Kat battles him, but she couldn't vanquish him with her casual sword, so Paw the Dog joins the fight and morphs into a gargantuan blade. With the help of Paw, Kat can finally defeat Boneheads after some effective slices. He degrades bone by bone. The prince is delivered from Boneheads' influence and Kat rescues Ana by cutting the rope with that she is captivated. At the end of the adventure, Kat, Ana, and their two animal partners along with the princess/prince being gleeful can be seen in front of the Castle.

Kat & Ana's microgames are themed after nature, and thus all of them feature animals or plant life in some way. The song Four Seasons plays throughout their stage.

In an unlockable minigame called Jump Forever, Kat & 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 & Ana perform in a television show called Super Show after 9-Volt's entrance. Under the headline "Karate", they show off their ninja techniques. However, it isn't known what occurs next because Wario's television set bursts.

Kat & Ana are two of the ten selectable characters in the multiplayer games.

WarioWare: Twisted!
In WarioWare: Twisted!, Kat & Ana go on a field trip with their kindergarten class on the Diamond Knoll. Their pets, Shadow the Dog and Shuriken the Falcon come along with Kat & Ana. The teacher instructs the children not to bunk. During the trip, Ana discovers a beautiful flower. While Kat takes a stroll, she and her two animal friends pause at the flower. Ana decides to show the flower to Kat and chases after her. However, Kat damages a beehive with a stick when she arrives. The bees get furious for being disturbed, so Kat & Ana sprint away from the swarm. They abscond into a wooden cabin and rest there for a moment.

However, Kat & Ana are not alone. They encounter the Diamond Troll. He immediately prepares his attack, so Kat & Ana quickly change to their ninja uniforms and attack him with their swords. Then, Kat & Ana charge their blades and shoot out a sword beam at the Diamond Troll. Shortly before they can attack, Shadow the Dog and Shuriken the Falcon crash right into the cabin and hit the ceiling. Then, they plummet into the Diamond Troll and all three are knocked out. Kat & Ana are speechless for a moment.

Following these events, Kat & Ana decide to return back home, but after they open the door of the cabin, the swarm of bees reappear. The two ninja sisters and their animal pals escape from the swarm in front of the sunset.

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

WarioWare: Touched!
Ana and Shadow the Dog stay in their house in WarioWare: Touched! Ana wants to eat bananas, so she opens the door to the room where the bananas should lie on a dish. She is shocked when she notices that the bananas are gone, and hectically searches the room. During this, Shadow the Dog notices animal footprints in the house. He informs Ana of the tracks by barking. She now also notices the tracks and sets off to find the banana thief. Before heading out, Ana writes a note for Kat so that she can know where to find her. Ana and Shadow the Dog dash out the door to chase after the culprit. Kat reads the note and catches up to her to retrieve the stolen bananas with Shuriken the Falcon.

Kat & Ana eventually capture the thief, who turns out to be a small monkey. They are initially angered, but the monkey quickly endears them, and they name him Numchuck. Kat & Ana cheerfully lift the monkey up and down and the thievery is quickly forgotten.

WarioWare: Smooth Moves
In WarioWare: Smooth Moves, the gargantuan, red Elephant Ogre comes to Diamond Dojo and stands in front of it at night. The concerned Sensei in the Dojo faces the monstrous being who suddenly lets out a piercing shriek. Quickly, Kat & Ana come to the Dojo's rescue. Ana gets inside the Dojo to reach the Sensei. When she arrives, she notices the Little Ogre bugging the Sensei and yanking his hair. Outside, Kat battles face to face with the Elephant Ogre. She activates her clone powers and five duplicates appear simultaneously, in which the clones immediately attack the giant with their swords. The Elephant Ogre's club and Kat's sword press each other, but then the Little Ogre shouts to stop the fight.

It turns out that the Elephant Ogre has just been searching for the Little Ogre, probably his child. With the Little Ogre on his hand, the Elephant Ogre peaceably leaves during the sunrise. Kat waves to say goodbye, but she suddenly notices that the actual Little Ogre is still there. The silhouette on the Elephant Ogre's hand is actually Ana. She desperately waves with her arms and cries.

Kat & 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 & Ana run the newly opened Wario Park along with Wario, Mona, and Jimmy T. All of their microgames in this game require two players. Completing their microgames make them remark on how close the players are, just like them.

WarioWare: D.I.Y. Showcase
In WarioWare: D.I.Y. Showcase, Kat & Ana have their very own stage called "Kat & Ana's Sky Patrol". In this stage, they jump off a cliff first only to fly above the sky using yellow capes in a fashion similar to Cape Mario and Cape Luigi. They are accompanied by birds (to denote the player's 4 lives for the stage).

Game & Wario
Kat & Ana appear in Game & Wario, where they host the Patchwork minigame.

Kat also appears as depicted on a bowling pin in the Bowling minigame with the other characters.

WarioWare Gold
Kat & Ana first appear in WarioWare Gold accepting Wario's offer to make games for him for the Wario Bowl, in which they host the second stage of the Touch League with a That's Life theme.

In their own story, the twins arrive at Diamond City Castle to find their teacher for a ninja test in hopes of getting their ninja learners permits. They encounter Ms. Munchly who they believe to be their teacher, who tells them that their test is to eat everything she dishes out to them, much to the twin's excitement. After eating numerous amounts of sushi, it is revealed that they completed the Gourmet Master test; their ninja test was right next door and their real teacher, Ninja Steve, was in the bathroom during their feast. Though full from eating, Kat & Ana join Steve to complete their real test.

They are later seen dancing at Club Joe with Jimmy, Mona, Dr. Crygor, Mike, Penny, Young Cricket, Master Mantis, and Fronk. They bring a large amount of food that attracts several customers to the club.

At the end of the story, Kat & Ana are among the group who demand their part of the money Wario made from the Wario Bowl. After Wario accidentally lets the briefcase with the tournament money fall off from his hands, Kat becomes disappointed to find out that the money Wario had with him was actually very little, with Ana deducing that Wario had probably spent most of it beforehand. They later gladly split the rest of the money with their friends.

Unlike in previous games, Kat & Ana have brown eyes instead of blue.

WarioWare: Get It Together!
Kat & Ana appear in WarioWare: Get It Together! In the game's story mode, the duo appears in the opening cutscene, eating food alongside Lulu. They, along with the rest of the WarioWare, Inc. employees, get sucked in the game world due to Wario's actions.

Their stage is the Nature stage, which is available after the Remix stage is completed. In the pre-stage cutscene, Wario and co. find Kat & Ana in front of their stage. The gang take notice of their constant jumping, and the ninjas state that they are unable to control their movement (although Kat believes that it is due to their abilities as ninjas). Kat states that she and Ana have seen a game bug enter their level, and asks the gang to help them.

In their story, a mysterious ninja named Leo arrives at Sleepytown Village and casts a Puppetry spell on all the animals of the village, who go rogue and wreak havoc on the inhabitants. Soon after, Kat & Ana arrive and retaliate with a Nap Time spell, clearing the rogue animals of their spell. Leo commands the dark animals to capture the twins and force them into the jungle, where they attack Leo with their shurikens. Leo quickly evades their attacks, and casts a Lion's Roar spell, turning himself into a giant lion. He then proceeds to escape into the jungle with the rogue animals. Without hesitation, Kat & Ana give chase. After their stage is cleared, the duo joins the gang, with Kat declaring the mission complete.

After beating Anything Goes, Kat & Ana go back to the real world alongside most of the other WarioWare Inc. employees and chase after Wario after it is revealed their predicament was caused by his poor programming. The twins reprimand Wario, who then remembers that other people were left behind in the game world. The gang immediately returns to rescue them.

Like Dribble & Spitz, Kat is controlled by Player 1 and Ana is controlled by Player 2; the player will always control Kat in single-player. As playable characters, Kat & Ana constantly jump, and can be moved left and right with. Pressing makes them throw a shuriken horizontally; Kat faces and throws stars to the right, and Ana faces and throws to the left. With these abilities, Kat & Ana can cover a wide range of the screen and clear out many objects with their attacks (e.g. Witch! Which? and Apple Drop, two of the 6 games that are considered a good fit). However, these advantages are overshadowed by the many disadvantages with these characters. Because of their nature of constant jumping, the player must time their movements to pass certain microgames without contacting undesired objects (e.g. Rock Candy, Fishy Felines). The inability to control their vertical positions also means that it may be difficult for the player to land accurate hits with the projectiles, such as in Matching Masks, requiring the player to choose the correct mask with pinpoint precision. Because of these disadvantages, Kat & Ana have 25 microgames that deem them a bad fit (the most out of any character, tied with 9-Volt), but a more balanced amount of microgames that deem them a below-average or average fit (70 and 79 respectively).

Super Smash Bros. Brawl
In Super Smash Bros. Brawl, Kat & Ana appear as stickers and together on a trophy. In addition, they make their first 3D appearance as Assist Trophy characters that soar across the stage and slash players with their swords.

Super Smash Bros. for Nintendo 3DS / Wii U
Kat & Ana return as an Assist Trophy and in Super Smash Bros. for Nintendo 3DS / Wii U. Their models have been updated to reflect the pair's Game & Wario design. They also have a trophy, like in Super Smash Bros. Brawl.

Super Smash Bros. Ultimate
Kat & Ana appear together in Super Smash Bros. Ultimate as a Master Spirit. In the game's adventure mode, World of Light, they own a dojo in the Light Realm, where they teach spirits the Ninja Style. This style gives a major increase to movement speed, falling speed, and the power of grabs, throws and attacks with items, but decreases the power of regular attacks and special moves, and also decreases defense and weight.

Rhythm Heaven Megamix
Kat & Ana make an appearance in the Wario... Where? challenge set of Rhythm Heaven Megamix. The ninja twins appear in the set's version of, with the player controlling them as they catch oranges and pineapples bouncing down some steps towards them.

Tetris 99
From September 17 to September 21,  ran the 24th Maximus Cup which featured a WarioWare: Get It Together! theme, where Kat is represented by the "T" tetromino.

Personality and abilities
Kat & 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, Kat & Ana are also displayed as quite naïve. While Kat is usually portrayed as being more focused and mature, in WarioWare: Twisted! she disturbs a nest of bees without thinking things through. Kat acts bossy which sometimes results in making Ana cry, but she cares deeply for her. Ana is quieter and more cautious than her sister. Kat & Ana are said to love especially animals and flowers, respectively. In WarioWare Gold, they are shown to have big appetites and enjoy eating large amounts of food.

The sisters are good friends with 9-Volt, as revealed in their diary. It is unknown how they became friends with Wario.

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

In WarioWare, Inc.: Mega Microgame$!, Kat & Ana created microgames of the Nature genre. All games involve animals or plants. WarioWare, Inc.: Mega Party Game$! also features Kat & Ana's nature microgames, plus a multiplayer game made by them, Wobbly Bobbly, which involves animals as well, namely tortoises.

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

Kat & Ana's five microgames in WarioWare: Snapped! require two players to play rather than one. After the end of their stage, photos of the two players with goofy decorations are shown. In Jimmy T.'s stage, a comic strip of them can be shown. In this comic, they have a fighting practice.

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

In WarioWare Gold, Kat & Ana host the second stage of the Touch League, of the That's Life genre, which includes regular day-to-day activities. All their microgames involve the use of touch screen controls.

In WarioWare: Get It Together!, Kat & Ana return to hosting Nature-themed microgames.

Profile page from the WarioWare, Inc.: Mega Microgame$! manual
"We're Kat & Ana! Yep, we're cute, we're kindergartners, and we're ninjas! We like plants and animals so much that we included them in our games. Apparently, we're graduates of Wario's school of kindergarten–at least, that's what the graffiti on the wall said! If I remember correctly, the teachers weren't too happy about that..."
