My favorites are alternate universe fics that explore other possibilities, and crossovers, as long as they are well written and in character. That's always been the challenge with crossovers, and one reason I like writing them is for the challenge.

I can't recall any specific fics off the top of my head right now, but I know there are some excellent ones in the archives. smile

I believe there's a hero in all of us that keeps us honest, gives us strength, makes us noble, and finally allows us to die with pride, even though sometimes we have to be steady and give up the thing we want the most. Even our dreams. -- Aunt May, Spider-Man 2
