Hm, I don't know which Arcana suits Lycodrake Aptera the most...maybe Fool, Chariot, Strength, Justice, or Star?
I'm really not sure.
Fool suits him in that he's still mostly innocent and naive, Chariot and Strength suit him because of his focus on control, Justice suits him because of his strong sense of morality, and Star suits him being a hopeful and "inspired" (because of Athena Nike) being.
At the same time, Persona-wise: Fool is jack of all trades - Lyco isn't. Chariot and Strength are physical attackers - Lyco is. Justice is light-based: Lyco isn't. Star is fire/heat-based and weak to ice: Lyco is.
