Adventures of the Super Sons #10

Peter J. Tomasi(w), Scott Godlewski(a), Dan Mora(c)

It's the runaway train from hell! Superboy and Robin better hold on for dear life as they ride a 20-megaton cosmic engine of mass combustion (that's a pun!) into their final battle with Rex Luthor! But Rex has got a brand-new army of shiny young super-villains ready to conquer all they survey. Will the son of Batman and the son of Superman be enough to stop him?
