 Bart Allan returns, apparently having resumed his thieving ways and working with Oliver Queen. In fact, Queen hired Bart, Victor Stone and Arthur Curry to help him destroy Lex s mysterious Project 33.1. On an intelligence gathering mission to a LutherCorp research lab in Metropolis, Bart ("Impulse"--to become "The Flash") is captured and Clark is caught in a Kryptonite store room trying to save him. With Chloe s help, Oliver ("Green Arrow"), Victor ("Cyborg"), and Arthur ("Aquaman") infiltrate the lab, rescue Bart and Clark and destroy the facility. Clark ("Boy Scout") is invited to join the new "justice" league, but he must refuse until he s captured all the Phantom Zone escapees.
