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 bird-like creature who attacks using her special sound-based 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.

Description
Kaley initially presents herself as peppy and upbeat, to the point of acting hysterical when revealing to Bowser Jr. and his minions that Bowser's Castle is under attack (which she is aware of as one of Fawful's minions). However, it is revealed that she is quick to anger; she also makes frequent reference to supplements in her dialogue, suggesting that she is dependent on them. Even though she is one of the Best Fitness Friends, Kaley is not much into fitness and eats a lot when stressed, based on Ludwig's intel while he was disguised as Beef.

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.

Profile

 * 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 does not involve the other two members. Dieter and Beef are only fought in levels that involve all three.
 * In the English version of Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, when encountering the BFFs in Bowser Path, Dieter refers to Kaley as Leana.
