I'll admit, I didn't much care for her at first, but she grew on me. IMO, she
just seems like a generic high school girl today. Can anyone tell me five
differences between Cassie's personality and Stargirl/Courtney
Whitmore's? And please tell me, what happened to the spunk?

******

Spunk becomes attitude in older teens.  She told off Robin for his trip around the world with Batman in a recent Titans in a way that didn't seem excessively angst filled to me.

I can't list five differences between Cassie and Stargirl because I don't know much of the character, but I can think of a few.  Stargirl seems to be from a relaitively tight-knit if blended family.  She's a junior member of the team who others try to help out with studying or whatever.  Cassie didn't even know her father, till he turned out to be Zeus, and as a former leader of Young Justice I'd say the Teen Titans think of her as senior member of the team.  See Cyborg going after her first when trying to get them back together.

Prove to me they are not currently written as the same generi-ficto-teen
stuffed into two identities.

Well, Stargirl is forward thinking.  She's looking to college and learning to drive.  Cassie is focusing back on Superboy's death and the Titans falling apart.  When Courtney lost her family she immediately focused on getting them back.  But that was an abnormal situation.

Cassie is angrier than Courtney.  The JSA hadn't been functioning as closely since Crisis.  She suggests they get back together more often, while Cassie is hostile to the Titans.

Courtney likes nice guys(Captain Marvel), while Cassie like attitude(Superboy)

Courtney is to content to learn from the best, working with the JSA, while Cassie is more comfortable with peers and being a key part of the group.

Courtney is apparently happy being a superhero.  Cassie has to be superhuman, see her deal with Aries as her powers faded, as opposed to maybe digging up her old bag of tricks.  THough I don't know if that's actually possible.

Do people agree with these assessments?  Or am I way off on either one?

< I guess some of this hedges on the situational. In your opinion, if they
were in each other's boots, how would the reactions differ? >

Hard to say really.  I suppose Courtney might be mor elike Robin who is trying to reclone Superboy.  I do know this isn't just a one time situation for Cassie though.  When Arrowette retired she seemed to be the one who had the hardest time letting go.

< More situational responses maybe. Is Cassie angry even when nothing
is going wrong? I want to know who they are in their everyday lives. >

I don't really know enough about them to judge that.  Though from this personality trait I'd guess Cassie is quicker to anger.  For example during one of the Infinite Crisis tie-ins she held a classmate to the ceiling for insulting Wonder Woman after the Maxwell Lord footage was aired.

< Perfect. This is exactly the kind of thing I wanted. Have we seen either
of them linked with guys other than the two you mention? >

Not sure about that.

< This is interesting stuff. Have they expressed these thoughts
themselves?

I believe she turned down membership in Young Justice where she'd obviously be considered an equal to remain with the JSA where even if they say she is their ages versus hers would lead them to try to protect her.

< Not sure what all this means. I'd appreciate clarification here. Are you
saying Cassie is a reluctant superhero? Thank you for the well considered
response. >

Actually just the opposite, Cassie is almost an overeager superhero.  Courtney is content on putting on a belt and picking up a control rod and letting that be her powers.  Cassie had something similar with her original costume and she asked for powers of her own.  She wants them to be part of her.  Take them out of costume Courtney is an ordinary human, Cassie isn't.

Courtney initially seemed to be moving towards Atom-Smasher, when he was a nice guy -- even one alternate future showed that they did wind up together - but when Atom-Smasher changed and became more ruthless, she had great concern for him, she quickly seemed to lose That sort of interest in him. 

(Just as a side note, Courtney was based on Geoff John's late sister, while i don't think he's used any particuarly model on his approach to Cassie, and of course has had to take what Young Justice and the Wonder Woman title left him)

< And I can't fault you for not knowing. I don't either! I say it's because
the writers have failed us. We have two heroines we cannot readily
quantify after years of stories. I like that example of her temper, but I
look at it this way -- In a comic, the hero's battle actions are reactive.
Character development needs a proactive component, and I can't help but
see it to be lacking for these two. >

Actually I can't because I'm only an occasional JSA reader.  I've read her in the Sins of Youth storyline, her guest appearence in Young Justice, the time travel Per Degaton story, and in the current JSA arc.

Oh, you mean a television commercial!
