Who we pick is...who WE are?

The title seems all philosophical right? Well, the post is not. It's an extended thought process of mine. So, a lot of people I know feel like they're a certain fictional character or would like to be one. They have a choice. Their reasons are all different. Some like the physique, some like the personality and some like both. What I was thinking is that do the characters we pick describe us in a way. I mean, say for someone who picked Batman, do they like to be the ones who save others, have they gone through something like Batman did, do the like his physique? What is it? It can't be nothing. Or maybe someone who wants to be,say an uncommon choice like, Agnes from Despicable Me? Do they find her cute or do they connect with her personality, because no matter how old you are trust is trust ( a major part of her character). Or am I overthinking this? It may just be a choice like any other. But then again, every choice has a reason. My apologies for being so confused and confusing you too. But I'm really curious. Think about a fictional character you would like to be and why? Then think if their characteristics match yours. I'm not sure if mine did ( in case you're curious I want to be Agnes). I'm sure something is common between us and our choice there has to be. So I believe, in the end, that the character we want to be describes us to an extent. (I hope I'm right because Agnes is pretty cute you know). 

  This extended thought process has been in my head since forever. Not really but a week at least. It's actually because I've had a long conversation with someone who believes that he is Batman and made me believe that I'm Agnes. Maybe we can see everyone as a fictional character. Then we might know what we think of them. If we're honest in our choices that is. But, think about it if u get 5 seconds to pick one character that best describes your friend then whom will you choose and will they match?  Give it a thought, fictional characters might be useful in reality now. Even if I am wrong it's a fun thing to guess fictional characters similar to people we know. So don't go away from this and say "what the hell was that?".
