Roger Stern's Will Payton will always have a soft spot in my heart, but I think the Ted Knight scientist approach may work better here, specially with the magic angle most characters have going. It'd really contrast. I think Prince Gavyn would work better in the pages of Threshold, but I wouldn't mind seeing him again. Always a fan of any Ditko stuff.
I Like the Jesse Quick idea, especially if her speed only manifests itself as flight, differienting her from the Flash. Wildcat has to be World Boxing Champ Ted Grant. It'll be no fun otherwise.
Maybe the second title Robinson will write will be JSA, leaving him free to develop the rest of Earth 2 in this book.
I'm really enjoying this.
