In my Final Crisis: Legion of Three Worlds post, I held back on posting the two single best things about the series so far. Well, I've kept myself from posting them as long as I could.
Below, you'll find scans that feature the return of Kid Flash (Bart Allen) and Superboy (Conner Kent). I'm looking forward to seeing how these characters are used in their return. Superboy will be part of Adventure Comics (with the new Legion) and Kid Flash has some sort of role in Flash: Rebirth.
