Leonardo is the oldest brother, tactical team leader, and eventual Sensei of the Hamato Clan and official boyfriend of Ivan


Leonardo Hamato is the disciplined, deeply responsible leader of the TMNT. Striking a balance between an anxious, tactical leader and a sci-fi-loving teenager, he strives to be the perfect shinobi under Master Splinter's guidance. His life shifts profoundly upon meeting Ivan, a same-age samurai and fellow disciple of Splinter. Experiencing love at first sight, Leo was instantly captivated by Ivan, who transitioned from a temporary ally to the person who completely won the turtle leader's heart. Now officially dating, Ivan serves as Leo's ultimate emotional anchor and safe haven. Bound by their shared devotion to bushido, Ivan's grounding presence alleviates Leo’s leadership anxieties, giving him a deeply personal reason to protect New York alongside his brothers and the samurai he loves.
