A new “Lego Dimensions” trailer has been released, and this time it actually involves the main story of the game and how all these characters from different franchises meet each other. Previous trailers of the game were character showcases for Doc Brown from the “Back to the Future” trilogy and every iteration of the Doctor from the “Doctor Who” television serial.

It turns out a new villain named Lord Vortech is the reason why the universes of these Lego characters have been merging with one another. According to an article from Comic Book, the villain has been summoning several characters from other Lego worlds to help him acquire these powerful bricks, which will apparently let him take over the world. Naturally it’s up to the heroes to stop him, including Batman, Wyldestyle from the “Lego Movie” and Gandalf the Grey from “Lord of the Rings.”

This is where the toy collecting comes in, as players will presumably gather an army of heroes, including characters from “Scooby Doo” and DC Comics, to go on various quests and stop Vortech from taking over the world, while also rescuing the Lego characters he has kidnapped. The trailer below shows Robin and Frodo as hostages that got sucked into dimensional portals, so it looks like it’s up to the three leads to rescue them and other characters.

The journey should prove to be an interesting one, as these characters will traverse through plenty of new territory, including the land of Oz, Metropolis and much more. Considering that more realms will be coming through some of the new toy packs, it’s clear that fans young and old will be playing the game for some time.

As Polygon pointed out, this is the first foray into the new toy gaming genre for Warner Bros. Interactive Entertainment. The competition could be stiff, though, with “Disney Infinity 3.0” and “Skylanders: Superchargers” currently dominating the genre, though the number of licensed characters might give “Lego Dimensions” a boost.

“Lego Dimensions” will be available for the PS4, Xbox One, PS3, Xbox 360 and the Nintendo Wii U on Sept. 23. “Lego Dimensions” Starter Packs will be available when the game’s released, with more packs coming this fall.
