Plot
As Sonic shows off his moves in the Watchtower Trainning Room and teaches the Titans in performing some of them, Justice League members watch news of Sonic's heroic actions on Metropolis, including saving the citizens from getting killed by Darth Vader, stopping Amon Sur's invasion and exposing Max Lord's villainny to public eyes, and find themselves greatly impressed. Meanwhile, in Soleanna, Princess Elise overhears of Sonic's disappearance and expresses her deep concern of him, on which Padmé assures her that he will be fine as Anakin Skywalker senses that Sonic's presence in the new universe is merging its Sun with the one of their dimension, although Anakin ends up experiencing the same vision Sonic saw while in the Chaos Control Vortex, and sees it as a great disturbance in the Force.

Right after overhearing of Sonic's story about his world, the Justice League discuss a plan to contact his dimension while Sonic, refusing to wait due to his friends' possible concern for him, thinks of a way to do the same in his own. Using the technics he learned in Soleanna, Sonic goes on a focusing ritual which allows him to connect his mind with other worlds. Elise is able to speak with Sonic through the same ritual and the two exchange loving sibling-like banters as Anakin senses Sonic enough to help Tails and Obi-Wan track his location as they hope that Sonic can find a way to contact them back. Just as the Justice League are contacted by Lois Lane about the Joker's plan, which is being supported by Lex Luthor's Society, they rush in to stop the villains and Sonic, sensing that the Leaguers' mission might give him an opportunity to contact his dimension, follows them.

The Justice League arrives in Metropolis to confront Lex Luthor and his Society and a battle issues. While the Leaguers keep Luthor and his group occupied, Sonic, Robin and Terra search for the Joker's Nuclear Bomb. As the two young heroes discuss an idea to defuse the bomb and free the Joker's hostages (as the Clown Prince of Crime is bringing on the challenge of chosing to save the city or the hostages), Sonic manages to replace the bomb's explosive capsules for six Motherboxes he collected from the Project Cadmus facility Max Lord was in. He also connects the bomb with his A.I. Nicole, who converts the bomb into an Hyperdimensional Portal Projector wth the Chaos Emeralds as the Power Core, and takes the capsules to other places the Society would not plan to explode, allowing Robin and Terra to free the hostages without concerning of the bomb as Lois and Barbara, who were spying on the field to report Metropolis about the Joker's mad scheme, interview Sonic about his plans. Seeing what the two are doing, the Joker presses the trigger, but ends up tricked by Sonic into exploding the other tools and protocols the Society members had built for their future plans: Outraged of this, the Joker goes to confront Sonic, who, able to see a scar in the Joker's body (which is the same scar he inflicted in the entity he wounded in the Vortex), recognizes the Joker as the homicidal threat he was warned about.
 * A Doomsday Weapon built by the Trench as ordered by Black Manta to help destroy Atlantis.
 * The Ur-Forge (a powerful device built by the Weaponners of Qward for the Sinestro Corps).
 * A statue of Athena built for Ares by the Spartans to be used as deception for the Amazons (similar to the Trojan Horse).
 * Poison Ivy's Botanic Lab, where she was working on drugs which would turn humans into plants.
 * A Lexcorp facility with Superhuman Clones in it.
 * The Joker's playground (it may not be any weapon, but Sonic targetted it as his punishment of the Joker's unwanted use of the Chaos Emmerald.)

The Joker attacks Sonic, who counterattacks and singlehandedly beats him down and "breaks his smile" (Sonic punches the Joker so hard he not only breaks his teeth, but also rips the Joker's smile tattoo off his face). The Society villains, seeing Sonic as the one responsible for foiling their plans, also arrive to challenge him, but Sonic proves himself a powerful fighter who defeats them all one by one before revealling that he (temporarily) knows all of their traits "thanks to the Joker". Accusing the Joker for "creating Sonic", Luthor rejects the Joker from the Society and they leave him behind. As the Leaguers voice their impressions of Sonic's performance, Nicole completes the device and Sonic reunites with his friends right after their universe's Sun completely merges with the one of the League's dimension. Just then, Sonic returns to the Leaguers' world and introduces his group to them, to which Flash comments: "Well... this just got a lot more interesting..."."'To Be Continued...'"
