Kaley

"How dare you question my fitness and my composure! I'll tie you to the squat rack by your tongue!"

- Kaley

Kaley is a member of the Best Fitness Friends and a major antagonist in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. She is a pink flying creature who attacks using sound based moves with her special skill Discord, which lowers allies' accuracy, and acts as the group's aerial fighter (with the Flying type status). Her name is a reference to, a type of cabbage with high nutritional value.

Despite acting calm in many cutscenes, it is soon revealed she is quick to temper and has a serious drug addiction, with Ludwig's intel when disguised as Beef suggesting she is highly dependent on the group's supplements.

She is first battled in Dimble Wood, after Ludwig reveals that he has been disguised as Beef for the last hour or so. She is then battled again in Bowser Path alongside Dieter and Beef, before being fought alongside the two of them in the final battle. She then merges with them to form the final boss before eventually being defeated for good.

Bowser Jr.'s Journey profile: ''The professional cutie of the BFF. At least, she usually talks in a cutesy way. But is that how she REALLY is...?''

Trivia

 * Kaley is the only one of the BFFs who is ever fought in a level that doesn't involve the other two members. Dieter and Beef are only fought in levels that involve all three.
 * Even though she is one of the Best Fitness Friends, Kaley is not much fitness. When she gets angry, she eats a lot, according to Ludwig.
