Elena cover
Elena Curry was born to her parents seven years ago. It was revealed in between Darla's Adventures of Lilo and Stitch that Elena used to live closer to the water until her family moved to Hawaii when she was three. She also has memories of spending time with her favorite uncle before he 'vanished'. Elena then finds out that Arthur Curry AKA Aquaman is her long-lost uncle and she is the long-lost Aquagirl. 

The shell necklace that Elena has from the May Day festival in Stitch Has a Glitch, is actually a gift from Aquaman before he disappeared and he tells Elena about her destiny. Elena also adopts Experiments 501 and 502 as her own pets as she shows concern for them, especially to 501 because Stitch harmed her while hunting for her.
