She's cute,she's smart but she's not perfect. She's shy(which i love about her) and another thing i love about her is here sense of humor.

I also like Margaret but she's just toooo close to perfect for my taste. And she realizes she's pretty,Eileen doesn't and that makes her really cute!

I seriously dislike CJ and i don't have much of an opinion on Susan..don't really like her either.

Margret's pretty hot.

Eileen is my definite favorite female character in Regular Show she isn't perfect but she's caring,she's nice,she's fun and she's an amazing character.

I like Eileen better. She cute, caring, smart! I really don't like Margaret. She's a whore to me. ((Sorry Margaret fans.))

Eileen is my favorite female character in regular show.she's cute ,nice, helpful,and smart.

Eileen is my favorite female character because she's funny, adorable, witty, smart, and cute! I find Eileen to be the perfect girl character in comparison with the others. I really don't like Margaret, but she's improving in the newer season. I feel like CJ is the better girl for Mordecai only because she's down to Earth, chill, and she actually has a lot in common with Mordo. I don't even know who Susan is......so I can't say anything about her.
I feel like Regular Show needs more female characters!!! I also like Starla a lot, but she isn't on this list.

Aw,i forgot to add Starla. :/ sorry. I like Starla too though.

And i should have added Audrey as well. >.<

(gonna add them now)

Also:Susan is the one who replaced Benson in 'Benson Be Gone'.

^ lol No worries! Starla is a badass.....hahaha
I forgot about Audrey......and I don't think I remember Susan. Time to go go watch the episode again!!!

I like Audrey so far. Not much of her personality has been shown but she seems very open and independent. (That's just my opinion though).

I think eileen is a great character, she is in my top 5 favorite characters but magaret is my favorite, i think she is just awesome, she so cool, and sweet, and shes smart to. But she can be a bit oblivious, but that just makes her'human'......

I like Margaret because she's pretty but smart also. Plus she seems to really like Mordecai especially in that episode where Mordecai was with CJ and CJ had her hissy fit and in the end left. She was acting a little jealous of CJ and also there was that episode where she kissed Mordecai on the lips before she left for her flight. It's so obvious....

I don't really go for the female characters but I'll pick CJ because she's fun
