I love all of the Secret six characters but I find myself missing Ragdoll most of all. It made me realize that I don't think I have ever read how you came up with such a lovely twisted character. How does one come up with Ragdoll?

Thank you!

This is a question with two answers. The Ragdoll-specific answer is that Ragdoll represents every outsider, every bullied kid who loves what he loves and doesn't QUITE understand what other people are saying most of the time. Ragdoll himself is joyous, but I find his observations often borderline tragic. 

Sometimes, a simple thing like cherry jello sends him into euphoria, so in a way he lives with the eyes of a child.

But the downside is, he can watch Deadshot shoot a female escaping slave in the back and not understand at all why people are sad about it. It's not a lack of empathy so much as that he simply lives in his own head so much that things that don't relate DIRECTLY to him at that precise moment, pretty much don't exist.  A cat, for example, doesn't care if you get the saddest phone call of your life. But if you left a grocery bag on the floor, that's the most amazing thing that ever happened. That's Ragdoll to me.

The larger answer is that you find that part of your brain that understands and empathizes even with the worst and oddest possible characters and you deliberately let go and live in their heads.  The act of writing serial fiction with extreme characters is not so much that of a storyteller, sometimes, but that of the quick change impressionist.  You have to learn to switch to your various virtual brains with every exchange of dialogue.

Hope that makes sense.
