Leon is a tall man with brown hair and magenta eyes with glasses. He wears a dark teal colored uniform with darker colored cape and underneath them is a long sleeved black shirt. He wears a belt with yellow PAC-man liked shaped buckle, long sleeved gloves and knee-length boots with Gold accents.
He is always smiling, or at least cheerful, regardless of the events taking place around him, giving little indication of his true thoughts on anything.
Leon is rather enigmatic. He is sarcastic and witty, sometimes even to the point of cruelty. Leon has a snide, sarcastic response to even the most serious subjects, and loves to tease his companions. Everyone is often unsure of whether he is being serious or not, though Leon has assured them on at least one occasion that he is "always serious". Regardless of his impish nature, the party trusts and respects Leon for his skill, intellect, and experience.
Leon's sarcastic and harsh words are often well-founded, and he uses them to express his often disapproving opinions. Other than amusement, Leon rarely shows any sign of his emotions. However, occasionally he loses his composure and his emotions burst out. Whenever Leon's feelings betray his calm and collected mask, he quickly distances himself from them. If he is furiously yowling at a character, when another asks what is wrong, he will quickly put on a small smile and act like nothing had occurred, which further rises suspicion among the party. Beneath his decidedly lively exterior lies a businesslike and scarily practical soldier's attitude.
- Leon is a character named Jade Curtiss from Tales of the Abyss.
- His height is 186cm and weight is 74kg
