Calling All Titans!
The Titans are riding back to the Tower in the T-Ship when Robin announces, to Beast Boy's disappointment, that they have one last mission to execute: In order to protect other young heroes worldwide more efficiently, Robin has decided to establish a communication network by giving a Titans Communicator to each. Despite Beast Boy's misgivings, the Titans split up and go on their separate missions, unaware that the Brain is using the captured communicator to monitor their progress to initiate the end-game.
Beast Boy climbs a tall mountain to contact Jericho, while Starfire aids Argent in repairing a leaking dam in New Zealand. Robin contacts Bushido, who is fighting a group of ninjas, while Cyborg goes to a wrestling arena where Pantha is battling. She grabs Cyborg, thinking he's a wrestler, and they fight briefly until Cyborg manages to inform her of Wildebeest's grim fate at the Brotherhood's hands, leaving her with a communicator. In another dimension, Raven meets with Herald and hands him a communicator, Terra gives one to Firebird, and Gigalith gives one to Ravager after proving herself.
Robin heads back and initiates a test of the communications network, contacting all the members from around the globe, but this only helps the Brain to pinpoint his targets more precisely. Immortus and his soldiers attack Argent while the Titans attempt to rejoin, and Robin sends Starfire to help her, but then more emergency calls come in. The Brain has initiated a simultaneous sequence of coordinated attacks against the Titans and their allies, who are currently spread too thin to aid each other effectively and thus become easy targets for the Brotherhood's cohorts.
Robin is helpless and despondent when Hot Spot arrives, but "Hot Spot" brutally attacks Robin, revealing himself to be Madame Rouge. When she gloats about the success of the Brotherhood's plans, Robin deduces that the Brain has tapped the communicators, and manages to slow Rouge down long enough to warn the others and rig his communicator to self-destruct, short-circuiting the rest, before he is captured.
While a few of the Titans have proved triumphant in their individual battles, Rouge brings Robin back to the Brotherhood's lair, tied up. He, along with Tempest, Speedy, Argent, Menos, Tramm, Thunder, Lightning, Killowat, Bushido, Supergirl, Lagoon Boy, Superboy, Aqualad, Sargent Marvel, Firebird, and Dove are all added to the villains' collection. After Robin is captured, the Brain starts gloating: "I have captured the king. Your pawns cannot save you. You have lost."
Titans Together
The Titans are defeated, and the Brotherhood of Evil appears victorious - but there is still some hope. Beast Boy manages to find his way to a secret Titans outpost, where he is soon joined by the remnants of the Teen Titans Más, Pantha, Herald, Jericho, and Ravager. At first the escapees are dejected that neither of them are among the most powerful (especially Jericho is held in little esteem), but Beast Boy holds them back and rallies them into a rag-tag, but in its own way effective team.
Their first undertaking is the capture of Cinderblock, who, thanks to Jericho's talents, provides them both with the location of the Brotherhood's base and a cover to get them inside. A slip-up by Jericho talking inside Cinderblock causes them to lose the latter advantage, and soon they must face the villanous assemble under the Brotherhood's leadership. Despite putting up a valiant fight, the odds eventually turn against the brave Titans, but just as things seem bleak, unexpected reinforcements arrive: Cyborg along with Kole, Gnarrk, and Green Lantern, Starfire bringing Bumblebee, Red Star, and Hawk, Raven arriving with Melvin, Timmy, Teether and their big friend Bobby, Gigalith arrives with Blue Beetle, Impulse, and Lilith, while Terra returns with Miss Martian and Wonder Girl- and the battle is quickly rejoined. During all this, Mas succeeds in reaching his brother Menos, unfreezing him after freeing Himself from Chang's goons by kicking one goon's shin, while biting the other guard's hand. By fiddling with the controls of Professor Chang's freezing machine, they are able to free the Titans who have been already been captured. Hot Spot, Wildebeest, Tempest, Tramm, Bushido, Argent, Killowat, Thunder, Lightning, Speedy, Robin, Supergirl, Lagoon Boy, Superboy, Aqualad, Sargent Marvel, Firebird, and Dove are freed from their flash freeze and quickly join the fight. With their numbers increased, the Titans easily overpower the villains. Last to arrive are Kid Flash and Jinx, who help mopping up the renmants of the H.I.V.E. Five and Madame Rouge and ferry the captured villains off to flash-freeze treatment.
As the numbers of their allies dwindle, the Brain and Monsieur Mallah decide to run for it, leaving the Brain's socket, which contains a nuclear device, as a parting "gift". However, Beast Boy and Robin apprehend the two, and the nuclear device is disposed of by Cyborg and Starfire, who shove it into outer space through one of Herald's portals. Finally, the Brain and Monsieur Mallah are frozen and the other Titans are groaning at Beast Boy's lame joke, "Brain Freeze."
Just as the Titans and Honorary Titans take some time relaxing in Titans Tower and getting to know each other a little better, they receive an alarm involving Dr. Light, who is robbing the Bank of Perez. Dr. Light later hurries out of the bank with his loot, unaware that over 30 Titans are waiting to pounce on him. As Raven puts it: "He's totally gonna freak this time!"
