I'm not sure if I can express my love for this character fully (despite the fact that it is no secret that I was once in love with this character), but I will make every attempt to make things at least appear clear.

My favorite comic-book character (or, manga character -- mangas are essentially comics!) would definitely have to be Sesshoumaru from the manga/anime series InuYasha.  The reasons are my own, but thanks to a request that I spotted, I have been given the opportunity to express them.

Sesshoumaru's personality in general was what drew me to him.  Sure, he's the expressionless, neutral, and almost hateful character of the series, but in studying him throughout the anime episodes and reading the manga through to the end, I have discovered that the initial reaction to him in his first appearance -- his whole personality, likewise -- changed entirely by the end of the manga.  At first, he was this calm, almost evil presence that was related to the hero Inuyasha (unwillingy) by blood.  He hated Inuyasha with every cell of his being, and he wasn't afraid to express this.  However, as the manga goes along, we discover that, for one thing, Sesshoumaru is only after what he feels belongs to him and not Inuyasha.  While it seems like he doesn't give a damn about Inuyasha's life, he really does understand more about why Inuyasha was given the Tetsusaiga and almost pities him.  Note my emphasis on the word "almost".  He still hates Inuyasha, but this seems to ebb away with the appearance/presence of Rin, his little human companion.  He is shown, eventually, to really care about this little girl, and so proves that Sess does have a heart.  He just likes to hide it so as not to appear weak.  He is such an interesting character that it led me to collect all of his appearances in the anime so that I could study him in detail. 

Another reason, which may not be as clear as the above, why I have a certain appreciation for this character is because he saved me from myself.  He set an example to me -- a proud, calm, collected, and almost arrogant example -- which, when I was about 14, I needed at that time.  When I was 14 years old, I was severely depressed to the point of suicidal.  One day, I was flipping through the channels of the TV when I saw Sesshoumaru during his second appearance in the anime.  He seemed so strong, and yet something about him led me to believe that there was more to him than I was seeing.  I grew interested in his side of the story, and not Inuyasha's.  Gradually, I started to show similar behaviors and tendencies that I had seen in him.  One day, however, was so bad that I was suddenly thinking about committing suicide.  As I lay in the bathtub about to drown myself, a sudden thought came to mind -- Sesshoumaru would never consider this as an alternitive, so why should I?  I realized that one of his appearances was coming on TV that night, and decided to make a "deal" with him:  I would watch the rest of the anime/manga through to the end, and only afterward would I allow myself to kill myself (if I still felt like it).  During the set time, I moved out of the environment that was causing my suicidal-ness, and found myself in a much calmer, predictable environment.  When 2008 came, and the manga ended, I remembered my deal and no longer felt the need for suicide.  Sesshoumaru had been there for me when no one else was.  He essentially saved me, and that is a major reason why I love this character so.

To this day, I feel a similar love for the character as I did back in that unpredictable environment.  However, it is slightly less like an obsession and more like a dependence.  I depend on him when I feel down and he is always there for me (in picture form, in plushie form, or in spirit) when I need him.  While he would not be up to this if he were a real person, I believe that the example he set for me is enough for me to get a sense for what he would tell me.  I consider Sesshoumaru my muse today, and no longer a fantasy lover.  I laugh about my obsession today, but perhaps later on I won't be laughing.
