Ha I understand that reference :P 

Like the IC said, this is always open newcomers are always welcome. 

In the CS thread I mentioned that your character could be as young as 16 or 17 as long as there's a good explanation for it. Being almost kidnapped is certainly a good one. But to go with the more realistic tone, there are no kid heroes younger than that. Child endangerment and all that. Though there will be plot-points involving superpowered children just not as PCs.
