Jojora

"I'm a buddy of the cousin of the descendant of the spirit who once guarded this palace."

- Jojora

Jojora is mysterious fairy-like girl who lives in Joke's End. She's just there because her friend's cousin's ancestor was the person who owned the place. Mario and Luigi have to fight her and one of her friends during a chaotic tea party during the events of Mario & Luigi: Superstar Saga. She even seems to take delight in toying with the Bros. while in the palace.

After making it through the entire palace, the brothers find Jojora in her room, where she asks them to sit down. She tells them that she admires their perseverance, and soon asks which "friend" they would like to meet for tea. After the Bros. select one, the chosen friend falls down from the ceiling and fights alongside Jojora against the brothers. When Mario and Luigi battle her they find she has an extremely high defense. In fact, most attacks only do one HP's worth of damage.

She also can wave her wand at them causing them to freeze, but if a Hammer strike is executed when she walks up to a Bro., the brothers can counter the attack and knock it out of her hands causing her to run away crying, "Eek! Uncool, you creep!". But this is short-lasting, as she will soon find her wand and return to battle. Also, whenever the Bros. damage her friend while she is still on screen, she exclaims "You NEVER touch a lady without her permission!" and begins a snowstorm that can freeze both of the Bros., and recharge the two ladies. But if she herself is attacked, no side effects occur. Because of this, the Bros. will have to time their attacks so her friend is only damaged while Jojora is off getting her wand, and unable to begin a snowstorm.

Trivia

 * It seems that Jojora has the highest defense in the whole game. Despite her high defense, however, Jojora can indeed be defeated, as unlikely as that might seem to certain players. The easiest way to do this is by equipping the Great Force to one of the bros., since it is the only way that their attacks will cause more than 1 HP damage, actually causing double. Experience is also gained. Thus due to this, Jojora seems to be the only boss in the game, besides Popple, who can be defeated but is not required to be defeated when battled, since both flee after their partner is defeated. (Despite this, during the Mario bros.'s third battle against Popple, Popple will not flee and must be defeated.)
 * Probably related to the above, Jojora's name sounds almost like Majora, the name of the villainous, murderous mask in The Legend of Zelda: Majora's Mask. The mask had high defense, and used magic-based attacks. The two both technically had a friend (or, however, Majora's Mask at least WANTED a friend,) were magical, and had high defense.
