Out of all the superheros I really think he might be my favorite (it's a tough decision w/ all the super-ness of superheros out there).
Dr. Abraham Erskine: "Do you want to kill Nazi's ?"
Steve Rogers/Captain America: "I don't want to kill anyone. I don't like bullies; I don't care where they're from."

A man who understands the value of human life. A man who is humble. A man who is steadfast. A man who leads. A man who willingly sacrifices himself before those that he leads. A man who is compassionate.
And can I be Arwen from Lord of the Rings? (I know not the same genre, but she is the best choice)
Witch King: "Give up the Halfling, She-Elf!" 
Arwen [draws her sword]: If you want him, come and claim him!
[as Frodo collapses and begins to fade]
Arwen: " Frodo, don't give in! Not now! What Grace is given me, let it pass to him. Let him be spared. Save him. "

A woman who is both beautiful and brave. A woman who is willing to give sacrificially of herself. A woman who is not hard and controlling, but one who is soft, nourishing, and inviting. A woman who inspires and encourages the men in her life to do what is right and to be all that they are meant to be. A woman who hopes.
How does a man become Captain America (or Aragorn would be a good one too)? How do I become a woman like Arwen? I've tried but... " I want to do what is right, but I can’t. I want to do what is good, but I don’t. I don’t want to do what is wrong, but I do it anyway. But if I do what I don’t want to do, I am not really the one doing wrong; it is sin living in me that does it.
I have discovered this principle of life—that when I want to do what is right, I inevitably do what is wrong. I love God’s law with all my heart. But there is another power within me that is at war with my mind. This power makes me a slave to the sin that is still within me. Oh, what a miserable person I am! Who will free me from this life that is dominated by sin and death? Thank God! The answer is in Jesus Christ our Lord. So you see how it is: In my mind I really want to obey God’s law, but because of my sinful nature I am a slave to sin." Romans 7:18-25
"This means that anyone who belongs to Christ has become a new person. The old life is gone; a new life has begun!" -2 Corinthians 5:17
"The thief’s purpose is to steal and kill and destroy. My purpose is to give them a rich and satisfying life."-John 10:10
Lord help me to be who you want me to be.
Someone who lives purposely and fully.
Someone who is glorifying to You.
Help me, because I can't do it without you.
