Watch Lego DC Super Heroes: Justice League – Attack of the Legion of Doom! (2015) Online Full Movie.
After the Justice League’s time stopping criminals, Lex Luthor bands together with Sinestro and Black Manta to form a team of their own which he dubs the Legion of Doom. Meanwhile, Darkseid is shown to have defeated the Justice League with Cyborg being the sole exception. Cyborg manages to defeat Darkseid and save the League. Unfortunately, this turns out to be a dream Cyborg was having. Cyborg wakes up just in time for the elections for the leader of the Justice League. Batman wins the election 3-1.
Elsewhere, Lex Luthor, Sinestro, and Black Manta uses an obstacle course to determine who will get to join them with the contestants being Joker, Man-Bat, Penguin, Cheetah, Captain Cold, Gorilla Grodd, Deathstroke, and Giganta. Giganta is rejected for her massive size where she wouldn’t even fit through the front door. Deathstroke is rejected for literally destroying the course as well as Lex overhearing Sinestro and Black Manta commenting that Deathstroke should lead the Legion of Doom. Joker, Penguin, and Man-Bat are rejected because the property that the Hall of Doom is on doesn’t have enough parking spaces.
After triggering a stink bomb recent battle with Trickster, Cyborg begins to doubt his worth on the League. Quickly, the Justice League becomes aware of the Legion of Doom and their plans to rob Area 52 (which was the successor to Area 51). The Justice League battles the Legion of Doom. Darkseid manages to use a Father Box to teleport Lex into a vault containing what he was after. The Legion of Doom escapes with a cell containing a specific alien prisoner. After opening it, the alien inmate is revealed to be a martian named J’onn J’onnz who Lex plans to use against the Justice League. He tells J’onn that the Legion of Doom are the good guys and the Justice League is evil.
Back at the Hall of Justice, Cyborg begins to question what he should do to be a better member. After a misconception from Wonder Woman, Cyborg gives himself excessive weapons. As he walks along the Hall of Justice, he appears to notice two Batmen. As it turns out, one of them was J’onn who hacks the Hall of Justice computer to create a false mission alert about the Metropolis power station where it’s prototype Nuketron reactor core preparing for destruction.
When the Justice League arrive at the power station, Cyborg sees that the station seems perfectly safe while the rest of the League can see the danger. This is because J’onn used his telepathy to make the fake mission alert look as real as possible as they evacuate Lois Lane and the workers alongside stopping other "problems" to the power plant. After the League launch the Nuketron reactor core into space, they immediately realize the only damage present is the damage they caused and the public turns against them for destroying the power station. The United Nations tribunal and Sam Lane sentence the Justice League to be evicted to space.
This however, turned out to be Lex’s plan all along and the Legion of Doom then begin to divide which parts of the world they will control. This results in J’onn questioning the affiliation of the Legion of Doom. While disguised as Black Manta, he soon finds out that Lex planned to dispose of him once his usefulness expired. In space, Sinestro uses the Father Box to send the Justice League to a black hole and Cyborg is destroyed in the process. Batman realizes that it wasn’t Cyborg, but rather Cyborg’s robot assistant.
The real Cyborg was still in the Hall of Justice trying to find out why the Justice League saw the power station in danger while he didn’t. He soon finds the microchip J’onn used to hack the computer, but Sinestro finds Cyborg and battles him. Just when it seems like Sinestro gained the upper hand, J’onn arrives and uses his telepathy to control him. J’onn explains how the Legion tricked him and how he tricked the Justice League into turning themselves against the public and that his telepathy was ineffective on inorganic beings, explaining why it didn’t work on Cyborg, whose brain was half-machine. J’onn sides with Cyborg and has Sinestro bring back the rest of the Justice League.
As the Legion of Doom attacks the city, the Justice League split up to battle them one by one. The Legion of Doom is defeated and the Justice League are cleared of all charges. J’onn apologizes for deceiving the Justice League, but he is quickly forgiven and offered membership for the work as a true hero he performed with the Justice League. He gladly accepts and adopts the name "Martian Manhunter" after a complement from Cyborg. When Sam Lane objects to the Justice League being forgiven for what they were tricked into doing, Martian Manhunter mind-controls Sam Lane to dance to the music that was playing.
Meanwhile in prison, Lex tries to get Darkseid to break him out of prison, but Darkseid refuses due to Lex’s failure. As soon as he hangs up on Lex, Darkseid decides that if he wants to conquer the Earth, he will need help from an otherworldly being.
