Sup! I play Leo (though from the IDW comics, not from 2012) at synodiporia, and because of the premise (it's all about travelling to alternate dimensions and different worlds), I've long thought it would be a pretty rad place to get together characters from different versions of the same series together. I live and breathe back-tags and I've found it pretty comfy; the tone varies depending on the world everyone's currently visiting, so we've had survival, horror, and slice-of-life all happen at various times.

The ad is right here if you'd like to take a look, and I think any of yours would be welcomed warmly, even if my turtle bias is obvious.
