Jonah al Ghul

Jonah al Ghul is the youngest son of Ra's al Ghul, the immortal mastermind behind the League of Shadows. Born Jonah Nine, he didn't meet his father until his teenage years, when he was brought to Infinity Island by his brother, Morgan al Ghul. Given a new purpose as an assassin, Jonah is deadly and dangerous, yet isn't as committed to the cause as most of his siblings, often only sticking around out of boredom.
