What is the name of the sequel to Lego Batman 2: DC Super Heroes?

The sequel to Lego Batman 2: DC Super Heroes is Lego Batman 3: Beyond Gotham. It was released in 2014 as the third main entry in the Lego Batman video game series.

The game follows Batman and other DC heroes as they confront Brainiac, an alien villain attempting to shrink Earth and add it to his collection. This story takes the action beyond Gotham, sending the characters to locations across the DC Universe and introducing a much larger roster of heroes and villains.

Lego Batman 3 retains the cooperative action, puzzle solving, character abilities, collectibles, and humorous presentation associated with the earlier games. It also continues the spoken-dialogue approach introduced by Lego Batman 2, whose characters had previously communicated mainly through gestures and sound effects.

Lego Marvel Super Heroes is a separate Lego superhero series, while Lego DC Super-Villains is a later spin-off rather than the direct sequel. Lego Batman 3 is therefore the precise canonical answer.
