âWhen I grow upâ part one! The sons of Batman and Superman have graduated to their own monthly comic-but if they want to survive, theyâre going to have to share it! Writer Peter J. Tomasi (BATMAN & ROBIN, SUPERMAN) teams with rising-star artist Jorge Jimenez (EARTH 2) to bring you the adventures of the Worldâs Smallest. This debut issue looks at the lives of Robin and Superboy and their destiny to follow in their fathersâ footsteps, while we meet a new villain whose ascension parallels the boysâ own understanding of their powers-except that he believes itâs his right to rule over every being on the planet!
