The film received generally positive reviews from critics.

Plot
The film opens with the Teen Titans Go! team battling the Gentleman Ghost as he attempts to rob a bank. He manages to possess Robin and then Starfire, but when attempting the same trick on Raven, he unwillingly cracks her gem, which unleashes some of her inner demonic power and results in his defeat. Trigon reveals that Raven's demonic half is slowly taking over her and offers to take it away, but she refuses to give it to him.

Suddenly, the Titans are abducted by the Master of Games, a being who explores the multiverse with his Worlogog to find the best versions of particular heroes. He pits the 2013 Titans against the original 2003 animated Titans, who agree to fight after the Master of Games threatens to destroy their Earths. 2003 Robin and Cyborg manage to take out all of the 2013 Titans with the exception of Raven. She is coerced into unleashing her demonic power against the 2003 Raven, who snaps her out of it when she realizes the Master of Games is siphoning her demonic energy. The Master of Games then reveals himself to be 2013 Trigon, who uses Raven's energy to resurrect 2003 Trigon. The two Trigons kidnap the Ravens and escape to the 2003 Earth to finish absorbing 2013 Raven's powers so they can conquer the multiverse.

The two Titans teams agree to work together to stop the Trigons and rescue their Ravens. 2003 Robin deduces that the Trigons are using a Worlogog from their Earth to travel between dimensions, so they need a Worlogog from the 2013 dimension, which the 2013 Titans realize belongs to Santa Claus. The two teams battle Santa and Mrs. Claus and escape by using the device to travel between dimensions and eventually make it to the 2003 Earth just after 2003 Trigon completely absorbs 2013 Raven's powers. Fed up with his counterpart's insults, 2013 Trigon consumes 2003 Trigon and transforms into a new powerful being named Hexagon.

To combat this new threat, 2003 Robin uses their Worlogog to summon Titans teams throughout the multiverse to form the "Titans of Infinite Earths", but to no avail. 2013 Raven evens the odds by absorbing all of her counterparts and transforms into a dragon known as "The Unkindness". The Titans destroy Trigon's Worlogog and assist Raven in getting her powers back, which sends 2003 Trigon into limbo while 2013 Robin uses their Worlogog to send 2013 Trigon to a zombie dimension.

After 2013 Raven accepts her demonic half, all of the Titans are sent home to their respective dimensions. Upon returning to their Earth, the 2013 Titans express relief that they do not have to endure another multiverse-threatening crossover for at least another year. Just then, they are attacked by Darkseid, but refuse to battle him out of exhaustion.

In a post-credit scene, the 2013 Titans relax at their headquarters, ignoring Darkseid's attack upon Jump City.

Reception
The film has received positive reviews from critics. IGN gave the film an 8 out of 10 stating, "Another awesome animated effort from DC/Warner Bros., Teen Titans Go! vs. Teen Titans is a super fun film perfectly primed to debut at San Diego Comic Con. Filled with classic characters and fan-satisfying fun, this chaotic cartoon crossover is sure to delight even the crankiest Teen Titans fans and the cheekiest Teen Titans Go! diehards. Basically, no matter where you're entering this arena from you'll have a titanic good time as you join these two teams on a multiverse-hopping journey through time, space, and... Santa!"

CBR.com gave the film a positive review stating, "Teen Titans Go! vs. Teen Titans isn't the most revolutionary film ever, nor does it reach the truly ambitious scale that last years Teen Titans Go! To the Movies or the thematically similar Spider-Man: Into the Spider-Verse managed to be. But as a love letter to the franchise that incorporates plenty of humor and heart, the new movie succeeds. The film proves that no matter what form they come in, the Teen Titans can have compelling and emotional stories, even amidst gags about superhumans fighting Santa's elves."
