Here’s my list. No specific order. Just how they come to my mind.
Silver Surfer - My childhood favorite still owns a 57% stake in my heart. That makes him majority owner. When I was a kid, I liked him 'cause I thought it was amazing to be able to go into space and surf anywhere, and to be able to shoot crazy RON LIM POWERBLASTS. As I got older, and maybe even a little bit more mature, it struck me how poignant the concept of his character is. He’s basically a messiah, except that the world rejects him. And he can shoot RON LIM POWERBLASTS.
Daredevil - If I knew this dude in real life, I doubt I’d want to be his friend. Dude’s a straight blowhard, an arrogant, self-righteous jackass. And a shyster. But there have been so many great stories in his comics over the years. All that Frank Miller stuff, the Bendis stuff, and now Brubaker. DD is just fascinating. I think he really goes to show that you don’t have to have a completely likable protagonist in order to tell memorable stories.
Spider-Man - Mary Jane loves Spider-Man. So do I. Come to think of it, I also love Gwen Stacy.
Cyclops - I used to not really like him when I was a kid, but in retrospect, I believe that was because his voice actor in the '90s cartoon sucked ass. That cartoon’s writing, and the voice actor, really made Cyke out to be a tightwad boy scout wuss. Everything he said was like, “No, Wolverine, you can’t DO that!” before getting elbowed in the ribs by Wolverine, doubling over in pain, shutting up, and letting Wolverine DO that. However, over the years, as I read more good comics, I gained a steady respect for him. (Plus, I like to pick him in MvC2.) I like Cyclops because he isn’t the stereotypical team leader. He’s got an insecurity to himself that makes him a great character.
(My other favorite X-Men are Nightcrawler, Archangel, Kitty Pryde, and Cable. But Cyclops is worth a spot in my top tier of favorite Marvel characters overall.)
Mister Sensitive - I love X-Statix. The characters all got a lot of love and development. Mister Sensitive and U-Go Girl had a super memorable story. I can’t really think of any other Marvels that touched me like that last X-Force arc right before it turned into X-Statix. Also, the X-Statix Vs. Avengers story, and the Mister Sensitive Vs. Iron Man story is one of the very best single issue fights ever. You’ll laugh, you’ll cry, you’ll scratch your balls in between pages.
**
Captain America** - I consider myself very patriotic and extremely pro-America. Can’t get much more patriotic than Captain America, baby… Living legend of World War II. A lot of times, I used to have the same problems with Cap that I had with Cyclops, but usually when a good guy writes the stories, I really enjoy his portrayal. I think he tends to be more interesting in Avengers comics, but I did enjoy most of the MK Cap series, and Bru has brought the heat. My other favorite Avengers are Hawkeye, Black Panther, Iron Man, and Thor… But Cap is just on the top tier of all-time Marvel faves. Cap is the perfect medium for my patriotism and my love of four-color fisticuffs.
Jessica Jones - I think Alias is one of the best things Marvel ever did. 'Cause it was a 28 issue character study, it just seems that Jessica is more real and more fleshed out than most comic characters. Like most any character in the classic, mighty Marvel manner, Jessica has some major character flaws, but you end up rooting for her nonetheless.
