You can stick a tiara on a villian, but you're still a villain

~Uma to Mal in Descendants 2

Uma is the main antagonist in Descendants 2 and the villain turned hero in Descendants 3. She is the daughter of the Sea Witch, Ursula, and the new leader of The Isle of the Lost. She commands a pirate crew which is kept in line by her first mate Harry Hook.

Rise of the Isle of the Lost
Uma is first introduced in the Descendants Franchise in this book. Here we learn about her background with Mal and the reasons why she hates her. As Uma grew up, so did her hatred for Mal.

Once Mal and her friends are taken to Auradon, Uma started to call them a traitors (mostly Mal) as the four had betrayed the Isle and its people.

Later on the book, when Uma hears the news about Tritons' Trident, she embarks on the search for it as a chance to leave the Isle.

Descendants 2
Uma is once again the leader of the pirate crew and the leader on The Isle of the Lost. Everyone is kept in line by her first mate, Harry Hook. She started off being extremely villainous, kidnapping Prince Ben, which forces Mal to bring a fake 3D printed version of the fairy godmother's magic wand. Before they hand the fake wand over, Uma orders then to demonstrate that the wand is real. Mal, using tactics, pretends to make Dude, Carlos's dog, talk, but he already could talk because he ate the truth serum that Mal made by accident. They give the wand to Uma, making her return Ben to them, and take the wand.

Descendants 3
Uma returned as the anti-hero, turnevillainan. She helps the Core 4 in defeating Audrey as long as Mal promises to open the barrier. Once Uma found out that Mal betrayed her trust, Uma stalks off with Harry and Gil. Later Mal keeps her promise letting everyone off the Isle. Uma, Harry, Gil and the rest of the Isle citizensns come to Auradon.
