Dude, why not? Arguing rocks.

I'm not exactly intending to just flat out argue and say, "You're wrong, I'm right." Like I said before, I just wanted to debate. I mean yes, if you look up in the dictionary, you can find that debating is a "argument about a particular subject", but debating to me is more of an elegant way of arguing. You are not just flat out saying, "This is my opinion and I don't like yours" and that's that, you might say, "I see what you mean, however, blah, blah, blah..."
Anyhow, back on topic:
1)Littlefoot: Not sure about arrogant, but if you mean stubborn, you've got my vote. Littlefoot rarely asks others for help, he generally does what he thinks is best, and doesn't sway for anyone's opinion except his own. The reason for this is, my opinion, extremely fourth-dimensional: I believe he's subconciously realized that no matter what he does, he will never in any way die or be injured. In short, he's discovered his character shield, and acting on it. There are scores of exmples to back this up. Just think about it: If you knew beforehand that, no matter what course of action you took, you would emerge unscathed and victorious, would you follow your own opinions, or someone elses?
I do agree that Little Foot by far is probably the strongest and most mature emotionally besides, however, in the tv series, he seems to act a bit "bratty" or "immature". Such as the "Sky Color Stone" episode. I do remember he seemed to be a bit "harsh" with Petrie in the first movie when he seems to be yelling, "You're a flyer, now start flying!" Someone might disagree and think Little Foot is simply encouraging Petrie in a "strong" way, he just seemed to have a bit of a mean streak in that part. However, Little Foot of course did see his mom die on the spot and I guess Little Foot was being impatient, but I think he could have been a bit more gentle with Petrie since Petrie is a bit of a sensitive guy.
2)Cera: You don't seem to say much here, except that she looks cute when she smiles. I guess so. But I think her friendly side is more submerged than you think. Remember in LBT 11, she goes through the whole movie disliking Tria, and it's not until Tria severs the reationship that Cera lets her "friendly" side shine through.
To see my full opinion about Cera go here:
http://z7.invisionfree.com/thegangoffive/i...?showtopic=13813)Petrie: I don't see Petrie as intelligent enough to act on his cowardice. He's a character who commonly accepts what is said and follows it: in "The great Circle celebration" he's practicaly religious about the sun, and it took his mother to convince him of Pterano's antagonism. I don't think he sees his cowardice as something bad; he merely accepts it for what it is.
Now correct me if I am wrong, but I believe their is a difference between naiveness and stupidity. Being stupid is when you have a lack of intelligence, but naiveness is when you may be smart, but you have a lack of experience in something.
Now it could just be me and my "fan girlyness" when it comes to this character, since he is my favorite one out of the five, but I honestly look at him closely and his facial expressions and I just see his frustration with himself. If you look in the seventh sequel, you see him being upset with himself when Ducky is kip napped and he just can't believe he trusted Pterano, he even says in the seventh sequel all upset at his uncle when he and his friends find the meteor on the volcano, "You lied to me uncle, you lied to everybody!"
I agree with you that he is a follower, but Petrie has proven himself to be "original" in the "Day of the Flyers" movie when he flies differently then everyone else. Also he tries to go against what Cera wants him to do, but in the end, he does so anyway, which I find sad.
4)Ducky: Again, adorable as hell, but not mature enough to recognize a basic personality quality as a fault. when Spike bumps her in, LBT 12 I think, she doesn't bemoan the fact that she's little, she says, "I do not like being knocked off ledges!" or something to that effect.
If you haven't seen the tv series yet, then well I understand why you would make this statement. Do recall though in the eighth sequel when she is getting lessons from Cera to express herself, same in a episode in the tv series, she gets lessons from Ruby on how to stand up for herself. In the Sky Color Stone episode, she gets all greedy when she finds the stones because she is afraid that Cera and Ruby will take them all away. While this is not the Ducky everyone knows and grew to love, I think it was an interesting twist on Ducky's personality since it showed her completely insecure side.
