Batman Animated Future Co-Stars?
The WB will have a new Batman animated series from next March, which will have a new wrinkle that back the history of DC Comics. "Batman: The Brave and The Bold" will have a different character co-star of each episode, as well as "The Brave and The Bold "comics from the mid sixties until 1983. Some of the first season guest stars will include Green Arrow, Robin, Plastic Man, the Beetle Blue (unfortunately, not Ted Kord version), and a Green Lantern or another, and characters not yet revealed. My question is: What DC characters that you I would like to see co-star in the new Batman series? (And I do not think any characters from the anime will turn up, so that the answers containing the names of characters Nippon Anime, or Marvel characters for that matter, will not be considered for best answer.)
I like to see him join up with Captain Marvel or maybe because it's something magic Zatanna Batman does not usually deal with
