Teen Titans: Trouble in Tokyo is a 2006 television animated film adaptation of the DC Comics superhero team Teen Titans. The film premiered on Cartoon Network on September 15, 2006 and on Kids' WB on September 16, 2006. Teen Titans head writer David Slack returned for this movie, having left the series after its fourth season (which was intended to be the last season of the show). It also as the series finale film of the Teen Titans (2003 TV Series).
The film takes place sometime after the events of the final season, where the Teen Titans come across a new villain named Sacio Tek. After attacking Titans Tower, the Titans discover he was sent by a menacing and mysterious Japanese criminal known as Brushogun. In order to solve the mystery, the Teen Titans travel to Tokyo, but have some difficultly fighting evil on the other side of the world. Meanwhile, Robin and Starfire are beginning to realize they can't keep hiding their true feelings and must decide if they ready to take a new step in their relationship
Jump City is attacked by a Japanese ninja called Saico-Tek. The Teen Titans manage to capture him having their tower damaged. Under interrogation, Saico-Tek reveals the identity of the one who sent him: Brushogun. The ninja vanishes and the Titans head to Tokyo, Japan, to search for its master.
Upon arriving Tokyo, after overcoming the language barrier (Starfire kisses a Japanese boy and learns how to speak Japanese, much to Robin's shock and jealousy) and fighting a Godzilla-like giant reptile, the Titans meet Tokyo's own supernatural defense force - the Tokyo Troopers - led by Commander Uehara Daizo. He shows the Titans around the Tokyo Troopers headquarters, and when Robin questions him on Brushogun, Daizo claims that Brushogun is nothing more than an urban legend. Left with no villains to pursue, the Titans can do nothing else than to enjoy Tokyo as tourists.
Everyone goes off to separate parts of Tokyo to do their own thing: Beast Boy follows a cute girl around and eventually lured to a karaoke bar, Cyborg goes to an "all-you-can-eat" restaurant, and Raven searches for book stores to read and incidentally finds a book describing the origins of Brushogun. Meanwhile, Robin and Starfire explore Tokyo, from boating through sakura trees, and watching a sumo-wrestling match to going to an arcade. During the trip, Robin and Starfire finally start to express their true feelings for each other while also explaining that nothing could ever get in the way of their friendship. They are about to share their first true kiss together, when suddenly Robin starts to focus on Brushogun again and tells Starfire that they are heroes, and they can't be anything more. Upset, Starfire flies away crying.
Investigating alone, Robin is attacked once more by Saico-Tek and they get into a very violent fight which ends with Robin pummeling the ninja into the ground. When Saico-Tek does not rise, the crowd watching believes Robin has murdered his opponent. Commander Daizo apprehends Robin, despite the hero's protestations of innocence.
Meanwhile, Beast Boy and Cyborg are now being chased by Beast Boy's fangirls from the karaoke bar (because they liked his performance) and the chefs from the restaurant (because Cyborg's bottomless appetite aroused their ire). Meanwhile, Starfire is alone by herself, where she deeply depressed from what happened between her and Robin earlier, soon a little girl appears and tries to comfort her. Starfire tries to hide her hurt feelings, but as the girl starts to leave, Starfire follows her and begins to explain her problems and admits she has had feelings for Robin since the day they met. She soon begins to lose hope, believing there is nothing more between. However, after the girl gives an encouraging and hopeful smile, Starfire finally realizes there has always been something more special between them, while also realizing that Robin has always returned her feelings, but is afraid to admit how he feels.
The Mayor of Tokyo announces Robin's arrest and orders that the other Teen Titans must either turn themselves in or leave Tokyo at once. Starfire calls the other Titans and tells them about Robin's arrest, they are about to regroup when Brushogun sends out his minions to destroy each of the Titans. Cyborg is attacked by a giant yellow robot who keeps trying to eat him, Beast Boy is attacked by a pink cat girl who turns out to be the cute girl he was following earlier, Raven is attacked by a ghostly figure in a graveyard and Starfire is attacked by a small blue robot boy in the sky.
Robin is transferred, when during the ride a slip of paper bearing the name "Brushogun" flits into the armored car carrying him and explodes, freeing him. Now on the run, Robin co-opts the identity of a Shinjuku, Tokyo mugger to collect information that Brushogun is in fact real, he is eventually found by the Tokyo Troopers which leads to a car chase, Robin is surrounded front to back and is about to be arrested when Starfire comes to his rescue. Starfire takes Robin to a secret hideout where she explains the situation, as she is about to leave, Robin stops her and they both try and kiss again when suddenly Beast Boy and the others barge in on them, who have come back safely.
Brushogun, as Raven relates from the book she found, was an artist who dreamed of bringing his beloved drawings to life using Japanese black magic. The spell turned against the artist and he was transformed into a being of paper and ink - ink that he could use to bring any creation he could imagine to life, thus becoming Tokyo's first super villain - Brushogun, until he suddenly disappeared. With this new information, and avoiding the Tokyo Troopers, Robin has no trouble deducing Brushogun's hideout: the manga comic book publishing factory. Breaking in, the Titans discover a withered form of Brushogun, trap wired into a cursed printing press that presses his powers to create the enemies the Titans have faced. He reveals that he had sent the first Saico-Tek to the Titans to lure them to Tokyo in order to stop the one who has enslaved him, who turns out to be Daizo, who has used Brushogun's power to create both his Tokyo Troopers and the monsters that they captured in order to gain a reputation as a hero.
A massive battle ensues, culminating in Robin facing Daizo. With no options of escape left, Daizo hurls himself from the catwalk, into the ink reservoir of the press, taking control of Brushogun's magic and transforming himself into a giant, hulking mass of ink and machinery, with Brushogun at the center, and creates multiple versions of his previous creations. As the other Titans battle creatures Daizo hurls at them, Robin frees Brushogun. As the old man peacefully fades away in his arms into the after life, his powers disappear and Daizo is left defeated and exposed.
With the battle concluded, Robin tries to explain his true and strong romantic feelings for Starfire, but getting the message, she silences him by telling him to "stop talking." The two romantically share their first proper kiss as the other three Titans look on, with Cyborg stating, "Well, it's about time" revealing that they all knew they were going to get together one day.
Later on, with Robin's name cleared, the Titans are awarded medals of honor by the mayor for their actions of unlocking the truth, and the inhabitants of Tokyo welcome their new heroes. Robin and Starfire are seen as a romantic couple, Cyborg earns the "all-you-can-eat" entirely, Beast Boy had become popular among the girls from the karaoke bar, and Raven been made a mascot for Japanese confections. Robin remarks that heroes could use a vacation once in a while and Beast Boy then declares that he wants to go to Mexico next year, prompting Raven to slap him in the back of his head; ending the film.
