Favourite OC?

Well, since I can't do polls because I don't have Core membership, I thought I'd ask you guys which OC of mine you favour the most. If you like all of them that's fine too. I just want some opinions from you guys about them such as whether they should be changed or are they too mary-sue or too bland or whatever.

First off, we have Carol. My very first OC. She originated after me but is now a part of the Fenton family as the youngest child after Danny and Jazz. She is very joyful and optimistic but can be modest, she dreams of being heroic and has a supportive family and close friend Celine.

Secondly, we have Amelia. An orphan since 13, she has been struggling with everything in life such as school, her relationship and sibling issues. She has a younger brother and lives with foster parents that don't treat her as nicely as her parents once did. She is moody, never smiles but is friends with Jazz online. 

Next we have Celine, a shy kindhearted and emotional teenager who has dealt with much trauma similar to Amelia but has lost her mother to a curse, in which she has to deal with. Her emotions are a strong struggle in her everyday life, if she becomes too negative she is transformed into an evil and powerful girl. She also has a minor crush on Danny but respects that he likes Sam more than he likes her.

Then we have Melinda, much like a showoff, tries to be modest but loves to be smothered in glory, she's a surfer and once lived in Amity Park before issues had risen and they had to move. Melinda is close friends with Jazz and is in a steady happy relationship with another surfer. Very beach themed and friendly.

Lastly we have Jessica, a kind and caring person, she grows curious very easily. Pursuing her career as a journalist, Jessica is suspicious of Danny due to the similarities he shares with his counterpart (unknown to her) Danny Phantom. She had lost her mother to a ghost and had a twin sister that was stillborn. She loves photography but can get too serious at times.

So, which one's your favourite? Personally I have no idea, I like them all. And I have noticed a recurring theme here, Amelia lost her parents, Celine lost her mother to a curse and Jessica lost her mother to a ghost. What's with me and getting rid of their mothers?
