Batman Ninja vs. Yakuza League

Gorilla Grodd's time displacement machine transports many of Batman's worst enemies to feudal Japan - along with the Dark Knight and a few of his allies. The villains take over the forms of the feudal lords that rule the divided land, with the Joker taking the lead among the warring factions. As his traditional high-tech weaponry is exhausted almost immediately, Batman must rely on his intellect and his allies - including Catwoman and the extended Bat-family - to restore order to the land, and return to present-day Gotham City.

Joker has come to Japan to steal the Eagle Talon Society's secret weapons in his continued scheme for pure chaos. However, the Justice League is on his trail, but there's something off with Batman. Now, it's up to Eagle Talon to go find out what's wrong with him, and that means going back in time to Bruce Wayne's most traumatic experience, the murder of his parents. The Eagle Talon Society also have to keep their eyes on their production budget, especially with most of that money going towards the licensing fee for DC's popular characters. Will the Eagle Talon Society and the Justice League be able to stop the Joker before their budget dries up, and they're reduced to simple stick figures!?

The ninja banish evil from the shadows. The gokudo gather lonely outcasts and commit crimes. The grudge they forged centuries ago is rekindled in the present day. The ninja Shinoha meets Kiwami, a gokudo with the face of a businessman. Unknowing of the other's identity, they bond over anime, but the war between ninja and gokudo intensifies. Who will survive and who will perish, ninja or gokudo?

The year is 20XX. The ninja, who once forged the history of Japan, were scattered across the country during the Meiji Restoration. As these ninja mingled with the other clans, their bloodline thinned, and they gradually faded from sight. The descendants of these ninja clans, seeking to preserve their heritage, formed the WNA (World Ninja Association) in the hope of carrying on their legacy. And so it was that the WNA succeeded in developing Ninja-Gum, an art which could summon forth the strength of the Shinobi. And yet creating the most powerful Ninja-Gum requires the strongest of ninja DNA. So it was that the Ninjala Tournament was held, that the mightiest of all ninjas could be found...
