Kiryu X trailer:

We see the camera flow in. A mechanical institution is displayed with Slade entering it. He begins to activate a machine, only to be greeted by the Titans.

As they battle, a deep rumbling is heard.

Robin: Aw, crap.

The Kiryu X is seen rising from the devastation, a being far larger than all other Titans villains combined.

The Camera fades in to another scene. The Titans hear a badly wounded and cut Raven saying, "Find Anung Un Rama."

Raven is seen in a nightmare, seeing a tall, mechanical form standing with a much smaller, more versatile form that she recognizes as Hellboy's evil half, Anung Un Rama! She stares as Anung begins to attack Kiryu X, trying to avenge her.

Kiryu X: "Anung Un Rama! Dare you continue with me?"

Kiryu X to Raven: "The days demand that you release your demon half. Release it or they die," and he gestures toward the Titans and Hellboy/Anung Un Rama. Godzilla is seen advancing on the heroes.

Raven, bound by a yoke that her powers cannot break refuses. Kiryu X begins to bring one of his blades toward the heroes. Tears fall from Raven's eyes, and she says the fateful words, "Anung Un Trigon"

A tall, red form stands before them all. Anung Un Trigon roars and stomps forth into the city.

Hellboy growls and he says to the Titans: Looks like its time to take care of business. Can't be any worse than the Moscow Incident.

Kiryu X, after the massive property damage, is confronted with the sheer power of Anung Un Trigon. She sings a song sung by an older hero, when he went to his death. Kiryu stares as Anung Un Trigon begins to attack him. He falls as Anung Un Rama appears.

Raven is speared through by Kiryu as the machine dies. Anung Un Rama becomes Hellboy again.

Kiryu X coming soon.
