Favourite Male Character (and why)

We all knew this one was coming. There's no point building it up.
It's Remus Lupin.

I've always liked him. Since the first time I read the book when I was ten, I have held this man in high esteem. In fact, I wished that I had at least one teacher like Remus Lupin. His patience, at least until the critical moment, seemingly knows no bounds. He is highly intuitive, creative, interesting, a bit kooky, and an all round general good-guy.
What I liked best (and really, huge kudos in the writing) was the dark creature within and the effects it had on him. Would he have been the same person without the bite? Of course not. In fact, though I think many of his defining characteristics could also be attributed to ten years growing up with Sirius and James, I believe it gave him his sense of humour, his need to fight for the underdog and his sense of justice.
There is a very fine line for Remus Lupin, between right and wrong. It's a line that few of Harry's mentors have. Sirius has a heart in the right place and a head that hasn't always quite caught up yet, Dumbledore is personification of a grey area and Mrs. Weasley's idea of 'right' is often, somewhat selfishly, Harry's safety.
Lupin understands Harry in a way he has never been understood before. He pushes him a little further than others have, but he knows Harry's boundaries.
I came back and read The Prisoner of Azkaban after six years of abandoning it and quickly developed a massive crush on this fictional character. You see, I began reading the Boggart scene as something of a fan, I ended it with a stupid grin on my face and heart palpitations.
As much as you will hear me moan about the film adaptation, this scene was done particularly well and I almost wish 'Professor Snape? Well, he frightens us all' had been featured in this chapter just so I could have loved him a little bit more from the start.
Of course, it's heartbreaking when this builds up to show us his true colours toward the end of the novel. When I realised he was in league with Sirius Black, I was devastated. I thought we'd finally found a decent teacher, maybe one who was going to be allowed to stay. I felt personally betrayed by him.
And immensely relieved when it turned out Black was innocent, Ron's rat was a murderer and Lupin merely on another mission for justice.
Mentioning my love for this character without mentioning his sarcasm is a travesty. When I talk about Lupin's defining moments, I usually mean the moment in the Shack that took this crush from 'Ooft. I would' to 'Marry me!'.
Despite this, my absolute favourite Lupin moment of all time has to be "One: he's sitting in my chair...". That scene sums up everything I love about this character. He's quiet and reserved in public. Around his friends, he's quirky, sarcastic and even quite sweet.
I suppose to cut a long story short, you could say I love this character's many dimensions. He's a werewolf, a teacher, a friend, a hero, a father-figure, a mentor and a Marauder.
He's all of these things over the course of four books, three of which he barely features in. That's quite an achievement.
