Queen Minnie

Queen Minnie is an original Disney character, and has appeared in Kingdom Hearts and Kingdom Hearts II.

Kingdom Hearts
She and Daisy Duck go over to the flowery courtyard, where they see Donald fussing with Goofy. They demand an explanation for that, so he hands over the letter he found in Pluto's mouth from King Mickey. She has them follow the king's lead, worrying for all of them as well as Chip and Dale, who are the engineers for the Gummi Ship. She is not really seen again until Kingdom Hearts II.

Kingdom Hearts II
When Sora visits Disney Castle, he finds that it is ruins because of Maleficent and Pete. He escorts Minnie to the king's throne, where a secret entrance lie for the castle construction site in the past (Timeless River). Minnie does not have any real offensive techniques unlike the the other support characters, but together she and Sora can use the powerful "Faith" technique, which temporarily banishes all Heartless in range.
