Saleen is a villain from the animated series Aladdin.
Saleen is a water elemental, specifically a siren, who schemes to have Aladdin to herself for no reason other than to win him. She has the abilities of a water elemental, as well as a variety of other abilities. One of her most prized possessions is a starfish that allows her to use various magical abilities. Her main associate is her octopus Armand. Uniquely, Saleen's fish features resemble a lionfish.
Saleen is first introduced in the episode "Elemental, My Dear Jasmine". She kidnaps Jasmine, after seeing the Princess being ridiculed by Aladdin. After giving Jasmine the ability to breathe underwater, she and Jasmine soon hear Aladdin's voice as he is looking for Jasmine. When she notices how handsome Aladdin is, Saleen decides to have him for herself and curses the Princess to remain in the ocean, but not before revealing that the curse will be broken once she returns. While Saleen goes onto land in an attempt to win Aladdin's heart, Jasmine tries to find a way to get Aladdin's attention. Thankfully, the Saleen's lair has enchanted water which allows Jasmine to connect with any water source. After the group finds out the truth about Saleen, Jasmine informs Genie of how to free her and the group tricks Saleen by taking her to a fake seafood restaurant (created by Genie) allowing them to use a hidden trapdoor to send her back to the water, thus breaking the curse. Saleen then faces Aladdin and Jasmine while Armand holds off the rest of the group. Aladdin and Jasmine hold her off long to enough for Genie to get rid of both Saleen and Armand.
Saleen makes a return appearance in "Shark Treatment". She steals a valuable statue bound for Agrabah to draw the attention of Aladdin. Once Aladdin arrives, she curses Aladdin using her Starfish. The curse slowly transforms Aladdin into a shark and places him under Saleen's control.
After Genie, Iago, and Abu fail in their attempts to retrieve the starfish and reverse the curse, they realize that Saleen's assistant, Armand, has been pushed aside in favor of Aladdin. The three take advantage of the octopus's jealousy and are eventually able to reverse the curse. Saleen tries to kill them all, but Armand traps her in a giant glass bubble, during which the Aladdin, Genie, Abu and Iago make their escape. Armand later sets her free, and Saleen vows that they'll get them next time, but she is never seen or mentioned in the series again.
Saleen's hair is the same color as the actress who voiced her: Julie Brown.
The word "saline" (of which Saleen is a homonym) refers to salt content - IE, 'saline water' would be saltwater.
Saleen's attempts to steal Aladdin for herself are similar to those of another Aladdin villain, Sadira. However, Saleen is considerably more malevolent in her attempts, and unlike Sadira, Saleen never changed her evil ways nor formed a friendship with Aladdin.
When Saleen uses her magic to give herself legs she comments: "Legs. What's the big deal?" It's a joke/jab at The Little Mermaid, where Ariel wishes to have legs to go to land.
