DC Comics

Titans by Tom Taylor Omnibus is about DC asking the former sidekicks to step into the space left by the Justice League. Nightwing, Donna Troy, Raven, Beast Boy, Starfire, Cyborg and Wally West are framed as a legacy family trying to become the center of the DC Universe. The volume belongs under Titans because the ensemble identity is the point: former sidekicks stepping into DC's center as a legacy family rather than a loose set of solo heroes.

Earth 2: The New 52 Omnibus Vol. 1 works because it is not simply alternate costumes. James Robinson, Tom Taylor and Nicola Scott rebuild the Justice Society idea after catastrophe on a parallel world scarred by Apokolips, where new versions of legacy heroes must earn meaning from ruins rather than inherit it cleanly.
