I really can't decide who my favourite hero or villian is.. Too many to choose from
But my favourite titles that are out right now are Runaways, Y: The last Man, Ex Machina, Ultimate X-men (Yah, I love BKV's work if you hadnt already guessed.), Noble Causes, Young Avengers, X- factor, Strangers in Paradise, Fables, The Walking Dead, Exiles(especially Winnick's run.), Cable and Deadpool, She-Hulk, Supreme Power, New X-men: Academy X, Teen Titans, and others that can't come into mind right now. (Yah, I read too many a month. I should really cut down on singles and go to trades.)
One Graphic Novel I enjoyed greatly was Blankets. Even when I read it now I still get teary eyed. Craig Thompson is a pretty awesome writer, I still have yet to read 'Good-Bye Chunky Rice' by him. Maybe I will get it for the holidays.
My favorite character is Dream from The Sandman. I thought it was interesting how he developed throughout the story. There was so much going on with Dream and how everything he did tied into the end...His dark speech bubbles were cool too.
I am a die-hard fan of Transmetropolitan. Spider Jerusalem-- and Warren Ellis by proxy-- is the man. I love him so much, I have one of his tattoos. There are a few other series/characters I like (My evil friend Twistex just got me hooked on Y and now I'm gonna have to read it), but Transmet has always been my favorite.
I really love Jhonen Vasquez's stuff as well as Hellboy and BPRD comics (Mignola is god). Then of course there's Sin City and Miller's Batman work. Same with Loeb's and Sale's Batman stuff. Also David Mack's Kabuki is just gorgeous. I've also been digging "The Walking Dead" stuff by Robert Kirkman and Tony Moore.
