Zelda is a minor character in the episodes. She is a good friend to Peach and originates as a major character from the Legend of Zelda.
Zelda seems to have different personalities depending on the setting she is in. At home and near friends, she is seen to be short-tempered, especially near Ganondorf and Link, however she usually does not break out into violence in the slightest way. In other places, she has a more calm and collected character, where she is seen as a little shy, but still quite talkative. Zelda doesn't express many signs of affection towards other characters, however in the non-MVP storyline, she does seem to act more politely toward Winder, which is a sign that she may have a crush on him.
