Plot
Superman, Batman and Wonder Woman stop another corrupt scheme by Lex Luthor and the Joker as they watch with a smile as their trainees Robin and Terra train together using the remains of Luthor's wreaked devices, much to Luthor's ire and the other heroes' amusement. As he overhears that Kara, Barbara and Cassie are buying suplies for Lois Lane's Baby Shower party, Batman still expresses his concern over the safety of Superman's family as he is sure the Joker might plan to destroy the Man of Steel's repultation just like it happened to the alternate Superman from the Regime Reality. Elsewhere, in another alternate reality, Sonic the Hedgehog is exploring Corruscant until he overhears Anakin Skywalker answer a distress call from one of the Clone Troopers and speeds up determined to help.

In Metropolis, Lois is having a happy reunion with Dinah Lance, Lana Lang and Vicki Vale, who are enjoying news of her pregnancy very peacefully, in a Garden owned by Madame Xanadu, who eventually advices them of an prophecy which is not far from being fullfilled: "Worlds will Collide, Heroes will Unite. Angels will Rise, Demons will Fall. Stars will Sing, Darkness will Scream. The Trickster banished, the Knight triumphs.", to which the women are puzzled but still impressed to hear. Back in Corruscant, Sonic joins Skywalker in his battle with his Sith Doppelgänger Darth Vader, who is leading a pack of Separatist Droids in caring a terminal bomb designed by Doctor Eggman and implanting it in Corruscant with the vile purpose to destroy the city and the Jedi Temple with it. Back in Ghotam, Robin and Terra continue trainingg until they end up finding an Chaos Emerald which had somehow just appeared in their reality. Just then, the Joker tries to shoot them in their back, but his aim his the Emerald, triggering its power.

In Corruscant, right after he and Skywalker defeat Vader and defuse the bomb, Sonic notice an Chaos Control lightning descending from the skies and, right after he links it with a Chaos Emerald he was holding and Vader prepares to attack him, the lightining engulfs both Sonic and Vader into an Hyperdimensional Vortex, where Sonic experiences a vision of an homicidal entity within the universe he is being transported into and wounds it with his sword; the progress also causes some pain in the Joker, which the other heroes cannot see through. Right next to the shopping Kara and her friends are, Sonic and Vader get teleported into Metropolis and, without regarding what is going on, Vader challenges Sonic.

The two engate into a destructive fight across the streets which ends up taking place in a Project Cadmus facility held by Maxwell Lord. The two are halted by the Teen Titans, who want them to stop before they can hurt any innocent citizens. Just as Vader attacks the young heroes as well, Sonic intervences and uses his Power Rings to block Vader's Force powers. Just then, Vader implants a terminal bomb (which will explode if directly touched) in one of the citizens, threatening to kill her. But Sonic, using the Jedi tricks her learned from Master Yoda, manages to freeze the bomb in one of his Rings and, using his Speed powers and acrobatic skills, throws the bomb away from Earth's atmosphere, where it explodes next to an incoming pack of Manhunters controlled by Sinestro Corps member Amon Sur, who is critically injured by the explosion. Maxwell Lord arrives in the situation to scold the heroes for the "mess they were causing" until Sonic, sensing darkness in Lord's soul through his sword, manages to quickly hack the facility and expose Lord for selling tech for supervillains, including Deathstroke. As Lord and Vader are taken to prison, the people of Metropolis welcome Sonic as a new hero before he is met by Superman, Batman, Wonder Woman, Green Lantern, Robin and Terra, to which Sonic replies: "This day's just getting a lot more interesting..."."'To Be Continued...'"
