1. Tim Drake
He is my number one favorite character (most likely because of his intelligence)
X-23 is how I got into comics. I saw her in X-Men Evolution and when I found out she was a comic book character I asked for issues with her in it.
3. Cassandra Cain
I liked her best when she only spoke in broken English. To me that kept her interesting and away from the Mary Sues. I still like her, but I thought illiteracy and trouble speaking made a good weakness.
4. Sailor Saturn
I watched Sailor Moon as a kid and Sailor Saturn always stuck out to me. I haven't read or seen anything with her recently, but as you might be able to tell from my username (saturnssailor), I really liked her as a kid.
5. Jason Todd
Originally one of my least favorite characters simply because I liked Tim Drake. I read more about him, got some of his comics, saw Batman: Under the Red Hood and I started to like him. I like him best in his anti-hero stage where he is killing people who he thinks need to die.
6. Rose Wilson
Angry, strong and a bit crazy. I like how she has a love/hate relationship with Deathstroke. She is a bit of a wild child and doesn't get along with a lot of people.
