Queen Ilene is an anime character who appeared in Lucario and the Mystery of Mew. She is the current queen of Cameron Palace. She is first shown during the tournament honoring Sir Aaron at her castle. Her Japanese voice actress is Momoko Kikuchi.
She a looks a lot like her ancestor, Queen Rin. About the only difference is that Queen Ilene looks much younger. She is about twenty while her ancestor, as seen in the movie, is probably around thirty.
She is a lot like her ancestor personality-wise. An example is when the Tree of Beginning began to collapse, she refused to evacuate, even though the tree crystals disappearing could mean the castle would crumble.
