Two spectral artifacts, the Amulets of Aragon, are worn by Princess Dorathea and her brother, Prince Aragon. Anybody that wears one of the two amulets transforms into a giant fire breathing dragon whenever they get mad. It is first seen in "Parental Bonding."
In the opening of "Parental Bonding," Dorathea turned into a dragon when she was denied to go to the ball by her mother, and escaped the Ghost Zone and attacked Danny in her rage. Danny defeats her by accidentally knocking the Amulet off (which winds up in his backpack). She is later able to retrieve it back. Danny and his friends encounter her in dragon form a few times before she used it to fight her brother in "Beauty Marked."
In "Parental Bonding," Dorathea's amulet falls out of Danny's backpack when he tries to ask Paulina out. To get her to come with him to prom, Danny pretended that he got it for her. Paulina accepts, not out of love for Danny or the necklace but because she sees it as the perfect opportunity to make Sam jealous. At the mall, Paulina was angered because they were out of fleecy T-shirts while wearing the amulet, and turned into a dragon and started wreaking havok. Danny defeats her and knocks the amulet into a bag that also contained a shirt in her size. Danny and his friends later discover its true properties and Sam convinces Paulina to let it go.
In "Parental Bonding," Sam tries to take it back from Paulina due to its ghostly properties, but she won't "return" it because she is still trying to make Sam jealous. When Sam says she isn't Danny's girlfriend, however, Paulina puts it on Sam's neck, reveals her affection for Danny was a ruse, and leaves to dump him. Angered that Paulina was deceiving her and using Danny to get back at her, Sam transforms into the dragon and kidnaps Paulina. She fights Danny in the football field, focusing her rage on Paulina, but Danny defeats her by wrapping her up with the Fenton Ghost Fisher and taking the amulet off of her.
In "Beauty Marked," Dorathea's brother Prince Aragon also owned such an amulet, which turned him into a black and purple dragon instead of a light blue one. Prince Aragon had more control of his transformation powers than Dora, but he was rendered powerless when Danny removes his amulet and was easily defeated.
