Super Smash Bros. is a 2013 American action sci-fi fantasy film by Paramount Pictures. It is once again directed by Jon Faverau, with Michael Bay in charge of the action scenes only. All the voices from the previous movies reprise their roles, including Hugo Weaving as Bowser. In the film, a secret organization recruits Mario and Luigi, Samus, Link and Donkey Kong to form a team that must stop Bowser from enslaving the human race with an army of Space Pirates from Metroid (film). It will be released in theatres on September 3rd, 2013. It is the fifth installment of the Nintendo Cinematic Universe. Despite being the most action-paced NCU installment, it is not the last one.
An organization named S.M.A.S.H. gains some intellegence from their spies that Bowser will soon return. The SMASH leader, R.O.B., decides to call upon a group of characters that could help them. They get Mario, Luigi, Link, Samus and Donkey Kong. They get Mario to the real world using a portal to get him from the Mushroom Kingdom, another portal to get Link to modern times, and Samus Aran gets to Earth on her ship, and Donkey Kong is brought there from DK Island.
Meanwhile, a group of Koopa soliders, including Kamek, fish Bowser out of the lava. Bowser is now nothing more than a skeleton. Kamek creates a spell that can bring the dead back to life. It works, and Bowser is back. Bowser reveals his new plan to his soliders. They are going to planet Zebes, where an entire army of Space Pirates lives. They get to Zebes, where they find Space Pirates that have disbanded since the death of Mother Brain in the Metroid movie. Bowser tries to convince the Pirates to join his army, but they refuse. Bowser uses Kamek's mind control spell to manipulate the Space Pirates into joining him and wait for the portal to get them to Earth. They say yes under the spell, and the Koopas proceed to head back to Earth. Meanwhile, the team gets taken to a military base that is owned by SMASH. John gets a report that Bowser has found an army and they plan to invade Brooklyn, Mario and Luigi's former home. Mario is shocked and says they have to stop Bowser once and for all. SMASH tells them they found this object called the Smash Ball a little while back, and they're testing it. It has the ability to open a portal, which could be used to unleash a Space Pirate army. They also say Bowser wants it. Bowser arrives on the SMASH military base. He basically takes out most of S.M.A.S.H and escapes with the Smash Ball. Eventually, Bowser makes it to Brooklyn and orders the Koopas to activate the Smash Ball that will send the Space Pirates to Earth, but Mario intervenes and tries to fight Bowser, but it's too late. The Koopas activate the Smash Ball, and an entire Space Pirate armada comes out of the portal and proceeds to attack Brookyln.
As Brooklyn is under an absolute state of siege, Mario angrily attacks Bowser for what he's doing, but is defeated, but Link, Samus, Luigi, and Donkey Kong arrive in Brooklyn and resuce Mario. Link orders Donkey Kong and Samus to defeat as many of the Space Pirates and try to get the citizens out of Brooklyn. Meanwhile, Mario and Luigi will fight Bowser, and Link will get the survivors out of the city. Donkey Kong starts attacking the Space Pirate Ships, while Samus uses her new rocket boots on her power suit to attack forces coming from the portal. Mario and Luigi battle Bowser, and Link tries to fight his way to find survivors. Eventually, the remaining SMASH forces make it to the scene and try to help the team, but a newly-upgraded cyborg Ridley comes out the portal and attacks SMASH, Samus, and Donkey Kong. Link uses a SMASH ship and arrives to the battle, and tries to help the Mario Bros. Samus goes to the Smash Ball to destroy it, but Bowser stops her and Bowser and Samus fight. Mario, Luigi, and Link join in and Bowser surpisingly can easily fight back against Samus, the Mario Bros., AND Link ALL at the same time. Donkey Kong then hijacks an alien ship and uses it to help his friends. He uses the ship's cannons to destroy the Smash Ball, closing the portal. The remaining alien ships and Mecha-Ridley are destroyed by the SMASH forces, and Brooklyn in enormous ruins, and thousands are dead. But, thankfully, the attack is over, and the rest of the Earth is saved, and Bowser is locked in the Federation Police Maximum Security Jail. After a massive battle, the team decides to take a break from saving the world, and the Earth remains at peace.
In a post credits scene, It is revealed that this whole time, Bowser was working for a much stronger force. His name is Tabuu. Tabuu is upset at Bowser for failing him, and tells his minions the time has come, hinting at a possible sequel.
