It's a toss up between Ichigo and Grimmjow from Bleach.
Lavi form D.Gray Man
L from Death Note
Death the Kid from Soul Eater (his OCD is just wow, cracks me up).

I would have to say Kurama/Yoko from Yuyu Hakusho, Yue from Cardcaptor Sakura, and Gojo from Saiyuki.

Favorite character is Hiei from YU YU Haksuho because he is at times misunderstood, but had a good heart like me.

Ooh, let's see!
I really like Chocolat from Sugar Sugar Rune, she's just quite goofy and laid back, I think it's nice that she's not like a lot of female manga characters,I find a lot of them are very stereotypical 'delicate flower' types'. I prefer a girl with guts! :D
On the same note I think Yukino in Kare Kano is refreshingly weird! :lol: I can relate to her a fair bit actually, and again, she's not a shy, perfectly well-mannered girl, when she feels free to be herself quite the opposite really!

I'm sure there are more than those two, but these are the first that come to mind. :)

Soubi from loveless.
Zero from Vampire Knight.
Hikaru and Kaoru from OHSHC.

:P

I think my favorite girl character right now is Ami from Shugo Chara and my favorite male character is Sebastian from Black Butler. Both are pretty awesome in their own right!

My favourite character is Byakuya from the series Inuyasha. I am also fond of Naraku - - and Hakudoushi.

Vegeta from Dragon Ball Z. o: He's so cool. And I laughed so hard when I first joined and saw the hair that looked suspiciously like Vegeta's.

Vegeta from Dragon ball Z, GT or L from Death Note. They're both pretty bad*ss

And many others.... You know... I'm sensing a theme here... =3

I have several Favorites, but the ones that stick out most are The Undertaker and Sebastian from Kuroshitsuji,along with Son Goku from Saiyuki.

At the moment, Hidan.

I could never simply pick one character from each Anime/Manga that I love, so I'll make a list of as many characters that I like as possible.

Yu Yu Hakusho: Kurama, Hiei, Itsuki, and my favorite female character from that show has to be Yukina, she's so sweet and cute. ^ ^
D N Angel: Krad, Dark, Satoshi, and I really like Riku, she was really cool, reminded me of myself and how I would handle her situation..
Demon Diary: Eclipse, Raenef Chris, Erutis and Krayon, I loved all of them, even though there were a lot of extra/side characters sort of... Eclipse and Krayon were my top favs, tied at first.. Raenef following right behind that tied with Erutis in second place and Chris would be in third place.
InuYasha: Sesshoumaru, Koga and Miroku... Miroku's personality always made me laugh...
Naruto: Itachi, Gaara, Naruto (simply because his stupidity makes me laugh), and others that I can't remember right now..

and there would be even more to add to this list, but I can't think of them at the moment... ^ ^

There are so many. Here are a few:
Naruto/Naruto Shippuden - Bee, Kakashi, Itachi, Shikamaru.
Dragon Ball Z - Piccolo, Vegeta, Brolli.
Death Note - L, Raito, Ryuk.
Soul Eater - Black star, Soul eater.
Avatar the last airbender - Sokka, Zuko, Iro, toph.
Inuyasha - Miroku, Naraku, Sesshoumaru, Inuyasha.

Right now it's Undertaker from Kuroshitsuji and Frau from 07 Ghost (watching both anime right now)

Ciel Phantomhive from Kuroshitsuji.
Oz Bezarius and Gilbert Nightray from Pandora Hearts.

My favorite anime male characters are Kaname from Vampire Knight and Ryoma from Prince of Tennis. (I can't choose between the two. lol) My favorite female anime character is Tomoyo from Card Captor Sakura. XD

L from Death Note. He is, in my mind, the perfect manga/anime character.

I also really like Sesshomaru from InuYasha. Don't ask why, I just find him really awesome.

It would have to be a tie between those 2, honestly. But if I had to pick one, I guess it would be L.

My runner-ups are Inuyasha himself, and both Keiichi and Rena from Higurashi No Naku Koro Ni. I love how insane Rena is half the time, and Keiichi is just awesome. I think Inuyasha is self explanatory. :drool:

Let's seee~

Matt and Mello from Death note. <3 Matt ftw. I lurve him.
Lain from Serial Experiments Lain. She's so weird. <3
Uryū Ishida, Kon, Noba from Bleach. :]
Hinata Hyuga and Pain from Naruto.
Rika Nonaka and, naturally, her digimon Renamon from Digimon Tamers.
Mio Akiyama, Azusa Nakano from k-on.
Nicholas D. Wolfwood and Knives from Trigun.

But, my favorite is...

Re'l from Ergo Proxy. <333333
(and Pino. <3333)

Aoshi comes across as being cold, ambitious and almost cruel when that's so untrue. He's extremely loyal to his men, treating them as though they were family. Being incredibly intelligent, Aoshi became leader of the Obiwanshuu when he was barely 15 years old, which is also testament to his strength. The loss of his beloved members made something inside him snap, which admittedly made him go alittle crazy for a while. But in the end, he helped Kenshin to defeat both Shishio and Enishi. I always will think that he's an honourable person and I believe his silent nature is as such because he's always thinking, always contemplating, observing and analyzing everything. I've been a fan of Aoshi for several years now, I'm pleased that I was finally able to get ahold of a figurine of him. : D!

He's awesome! my favorite is Sanosuke Sagara from Kenshin too =3

Spike Spiegel. Hands down. Cowboy bebop was one of my first anime, and I have seen a lot of anime since then. Spike is still one of the best developed characters of all time. Between his deep past, his amazing voice(in the dubbed version), his somewhat disheveled sexy look, his funny yet intense personality, and his fantastic martial arts skills he is perfect.

And to toss a woman in there, my favourite Female character in RE-L Meyer from Ergo Proxy. She is kind of a badass, but she still has that weak side about her that makes her more of a realistic character. She reminds me a lot of myself, which is likely why I like her so much. I have been told quite a few times that I could cosplay her really well.

Definately Sunako, from The Wallflower.
She's so adorable ^^

honestly, i have so many that its hard to name them all. Rina from Pichi Pichi Pitch (mermaid melody), Orihime Inue and Rukia Kuchiki from Bleach, Chikane from Kanazuki No Miko; all characters from Inuyasha; Anne from Anne Freaks, Rinee' from Tokeyo Mew Mew (the american version also known as Mew Mew Power); Sailor Saturn from Sailor Moon; Lucy/Nyu from Elfin Lied; both Nana's from Nana; Yuki from Vampire Knight; and Karin from Cibi Vampire
