When Alex and Omni messed around with the cloner after Tonto redesigned it, they ended up mixing together 4 different sets of DNA, creating two clones, but aside from Copium existing in their DNA structure, they show no signs of being clones. They were created as babies and shot out of Omnimation by the two by mistake, after names had appeared to them; and found by Artemis and her hunters
The first, is a girl with dark black hair, pale skin and blue eyes, one a icier shade than the other, called Leia, the DNA that makes her up came from Thalia Grace and the person who Kronos possess; Luke Casalatan. She has ADHD, Dyslexia and a fear of heights; and snakes. She has the power of electrical control, and teleporting; hailed from her parents, but her powers were locked by Tonto before they got rocketed to hide her identity. She is said to act like Thalia, and is a hunter; both are age 20 but are in the appearance of 10 year olds thanks to being hunters
The second is also a girl, and most horribly of all, the DNA used on her was that of Artemis and Tonto. Her name is Diana, and like her father is a very gold hearted, if a little goofy, member of the hunters. She has blond hair from her fathers side, but has the fair skin of her mother. She could possibly unlock the powers of the gem gods, like Percy or Thalia, but Tonto locked her powers to hide her identity. But like Leia, her powers could be unlocked by Tonto when he so chooses.
A third clone, a boy, at age 17, was a clone of Roxas and Xion's DNA samples. Sora created him by mistake as a baby when he came upon Tonto's old cloner. He had Roxas's hair style, in Xion's black. He is the heir to the clone world, Rion
