Infinite Crisis - Doom's Day
An Infinite Crisis tie-in. Superboy from Earth-Prime arrives at the Kent farm to challenge Connor, whom he regards as a poor hero unworthy of the name Superboy. But the intruder proves he is a villain, attacking brutally, endangering the Kents, harming Krypto, and murdering Pantha, Wildebeest abnd Bushido almost inadvertently. He even manages to break free of the Phantom Zone (sent there by the mysterious blue arrow Speedy has been carrying around). But he is finally defeated. Will this bring Superboy back to the Titans? Beast Boy visits the Doom Patrol because he wants to know why Rita Farr is no longer dead. But the Doom Patrol has no idea what he's talking about, until the Chief recalls a shared nightmare and speculates that the universe is re-aligning and the brains of mere humans are struggling to keep up with that...
