Personality

 * Chris:"Is that the real reason you're looking for the keys? To stir up trouble?"
 * Karen:"I guess it is, yeah."
 * —on the search for the Kingdom Keys

Karen is outgoing, talkative, and friendly, but tends to lose her temper frequently, especially when one of her friends is threatened. In her teenage years, she was somewhat irresponsible, though less so than her brothers. Like her brothers, she's a bit of a gaming geek, though not to the extent that her brothers are. Her favorite activity is combat sports and she looks forward to the annual Battle Royale every summer.

Abilities
Karen is talented in the arts of the Plumber, passed down from father to daughter. She excels in close combat due to her size and dexterity but has trouble aiming ranged attacks, especially electric attacks. Being a Pikachu, she naturally has the ability to understand Pokéspeak and generate electricity through her metabolism. In addition, she can generate flames from her paws and use them for many purposes. When combined with Amy's ice or Aaron's water, for example, she can create a cloud of obscuring mist or relaxing steam, respectively.

Early life
Karen lived a sheltered early life as a human with her family on Fraternia Island. Her closest friends were her brothers, sister, and cousin, though she had also befriended the few other children her age who lived on the island. The only real troubles were the local bullies.

Aaron Goes Missing
This all changed when a mysterious mage attacked Fraternia Island, aiming to kill the family of Pikachus who were visiting at the moment. Aaron rushed to the island's defense, but proved to be no match for the mage and was thrown into a dark portal along with the Pikachus. Karen, hoping Aaron was nearby, spent a great deal of time afterwards searching for Aaron around the island, but was unable to find him.

In the summer of 2006, King Bowser I held a number of Battle Royale contestants for ransom, just to troll the contestants' homelands. Cutting off all transportation in and out of the country, and blocking the warp pipes, he demanded a hefty ransom from Hyrule, the United States, and Nowhere for their prized athletes. Karen, excited by the prospect of saving the world from potential war, set out to recover the seven keys to Bowser's vaults, inside which was a key that could unblock the warp pipes and let the foreign athletes escape. She was joined by John and two of his friends, who found themselves trapped in the Mushroom Kingdom during their pursuit of James. After a quest lasting about two weeks, Karen found the keys, defeated Bowser, and enabled everyone to return home safely.
