Usual Suspects

December 30: Red Arrow, Icon, Plastic Man, The Atom, and Doctor Fate are welcomed into the Justice League while Icon's prot?g? Rocket joins the Team. During the ceremony, the Team receives an alert about Cheshire boarding a plane. After finding the plane crashed, the group is attacked by the Riddler, Cheshire, Mammoth, and Shimmer. After winning the battle, the Team recovers a suitcase containing heavily-modified Starro bio-technology and deliver it to Batman. Later, Superboy takes the Sphere to Santa Prisca after receiving a message from Lex Luthor, finding Luthor, Queen Bee, Cheshire, Sportsmaster, Bane, and Blockbuster there. Artemis and Miss Martian arrive separately, causing the three heroes to display shock at each other. However, in flashbacks, these three reveal their secrets to the rest of the team, showing their current actions as a ploy to lure the villains into the open. The Team defeat all but Luthor and Queen Bee, who escape by helicopter, and Chesire who disappears as Sportsmaster is captured. In the Watchtower, the mole is revealed to be Red Arrow who was brainwashed into using the biotech to gain control of the entire Justice League. A mind-controlled Batman authorizes Vandal Savage's entry into the Watchtower.

In Young Justice, being a teenager means proving yourself over and over- to peers, parents, teachers, mentors and, ultimately, to yourself. But what if you're not just a normal teenager? What if you're a teenage superhero? Are you ready to join the ranks of the great heroes and prove you're worthy of the Justice League? That's exactly what the members of Young Justice- Robin, Aqualad, Kid Flash, Superboy, Miss Martian and Artemis- will find out, whether they have what it takes to be a proven hero.
