In no particular order, numbers are purely for keeping track.
10. Seras (Hellsing)
Dont let that cute little button of a face fool you. She will EAT YOU.
9. GLaDOS (Portal)
Dont let that sweet singing voice fool you, she WILL kill you. And she ate all the cake. It's gone now.
8. Kirby (Kirby)
Dont let that marshmellow cuddliness fool you, there is no more terror than being sucked into it's infinite void of a belly!
7. Rider (Fate)
DO NOT LOOK INTO... crap, you looked into her eyes didn't you?
6. Pikachu (Pokemon)
It might look friendly, but I doubt you'll think so when it's coursing 9,001 volts through you.
5. Sailor Scouts (Sailor Moon)
Since I apparently didn't have a piccy of any of them alone.
4. Misa (Death Note)
Because getting on the bad side of a bubble headed sweetheart that can kill you in a pen stroke, is a really bad idea.
3. Hanyuu (Higurashi)
Since a god that can rewind time and make you relive the same day for hundreds of years, is NOT something you want to upset!
2. Tali (Mass Effect)
A technological super wiz is not someone to scoff off! No matter how pink it maybe, you should of learned that alreayd with Kirby!
1. Because I have no idea who she is.
And number one, since I ran out of cute things that I recognize, Red hat girl, because those fangs are very suspicious when you hoola hooping while playing "Are you the Werewolf".
