It's okay if there's another Batman type I guess. I was actually maybe planning on making him quite a bit more crazy and paranoid than Batman since I've done that in some other RPs and it's worked out well enough then, so a bit more like if Batman were crossed with The Question from JLU I suppose, if The Question were capable of functioning in society. 

Also the fact that I'm playing Batman in another RP helps lessen my concerns. XD

With those things in mind I might remove him from affiliation with The League and make him more of a crazy, myth-shrouded conspiracy theorist at least at first? I'm not sure unless you have suggestions. I might wait until you finish Pariah before I write the rest of him up so they don't get too similar? Because if Pariah is ALSO a crazy myth-shrouded conspiracy theorist who dresses like a creature of the night or something, well that would just be silly.

Although if it IS the case that he's a crazy-prepared conspiracy theorist which seems like the kind of person you'd give the name 'Pariah' to, I have other angles I can approach Strix from.
