#1: Gibby (very funny)
#2: Nevel (we need to see the antagonist a little more)
#3: Ms. Benson (although, I personally find her a bit annoying, she is funny at times and I know a lot of people like her)
I understand how people want Wendy to become a main character, but I just can't see it happening. She barely shows. Maybe a major recurring character, but not a main character.
