No Social Skills: Adrian openly admits to lacking social skills, and generally avoids talking to people outside her social circle (which she still has her moments within). Raven often encourages her to go up and interact with others, much to Aden's chagrin.
Ambiguously Bi: She refuses to state her sexual orientation, and given her relationship with Aden, she very well could be gay. Still, she does seem to like boys, so...
Green Thumb: Averted, which is ironic, considering it's technically her element. Then again, she merely manifests her element (wood) in the form of Paper Control, since paper is technically made from wood.

In fact, she's definitely this for Aden, whom she occasionally pushes to talk to others in order to help the latter get over her social issues. Adrian really wishes she didn't.
Meaningful Name: His last and middle name s. His last name, "Knight," is a reference to his status as The Lancer, along with his unique set of skills. He is also sometimes referred to as "The Dark Knight".
His middle name, "Meridith," means "Lord of the Sea," which alludes to his elemental water powers.
Morality Pet: Aaron, who he treats like his little brother.
Child Prodigy: Around 10 years old and already in the 6th grade. Did we mention he's good at chess and plays two instruments? one of which actually sounds good?
Wind is Green: His motif color and wings are a pale shade of spring green.
The Valkyries

Anti-Villain: Once we find out she wants to get out of Pandora and be free. She believes obtaining the elementals is her ticket out. Though her methods are rather questionable...
