James! He is literally my favourite character in the entire book series (tied with The Boy Who Lived, of course). I do love Sirius, but James... I don't know. I've always adored him. I love how annoyingly twat-ish he was. I love how funny, intelligent, sarcastic, self-assured, and immature he was. I love how he changed when he was with Lily; he was still annoying and all that, but he was more open with his sweetness, affection, and love. And he was incredibly loyal, brave, and a trouble-maker to boot. Basically my description of a perfect human.
