Toonvengers: Endgame

Kids Next Door: Endgame is a 2001 American animated adventure crossover film produced by Mitchell Movie Productions and Distributed by Luigidollar Pictures.

Set five Weeks after the cataclysmic events of Dark Danny's victory, half of the universe's sentient life is gone, and the completed Reality Gauntlet has disappeared with the Mad Titan to a faraway world. However, even in this seemingly hopeless situation, the surviving heroes of the universe (Supers, Guardians, and anyone else who is brave enough to fight on) are left to pick up the pieces. With a bit of hope, they intend to revive their friends and allies and the untold trillions of living beings that Dan killed, and find a way to defeat him once and for all. But it won't be easy, and devastating sacrifices will have to be made in order to restore reality to a normal state.

Kids Next Door: Endgame opened on Thanksgiving 2001 to wildly successful box office numbers, eventually grossing over $497 billion. It received critical acclaim, with a rare 100% rating on the website Rotten Tomatoes. It is considered by critics to be one of few sequel films superior to the original and is frequently featured on lists of the greatest animated films ever made.

Plot
In the distant apocalyptic future of 2019, Stan Smith is horrified to learn that his interference in 1998 with the Sokovia Accords has lead to the events of Reality War, realizing how important Kids Next Door were, Stan and the Enchanted one go back in time to fix Stan Smith's Mistake.

Two days after Dark Danny used the Reality Gauntlet to disintegrate half of all life in the universe in 1999, Penny Peterson rescues Dee Dee, Dexter and Bebe from deep space and returns them to Earth. They reunite with the remaining Kids Next Door—Beetlejuice, Stan, Zeke, Helga Pataki, AJ, Ed, Jimmy Neutron, Cindy, Libby, Sheen, Carl, and Jenifer—and find Dark Danny on an uninhabited planet. They plan to retake and use the Reality Gems to reverse the disintegrations, but Dark Danny reveals he destroyed them to prevent further use. An enraged Zeke decapitates Dark Danny.

Five weeks later, and with the help of Stan Smith and the Enchanted one, Lincoln Loud escapes from the quantum realm. He travels to the Kids Next Door compound, where he explains to Pataki and Neutron and his friends that he experienced only five hours while trapped. Theorizing the quantum realm could allow time travel, the three ask Dexter to help them retrieve the Gems from the past to reverse Dark Danny' actions in the present, but Dexter refuses to help. After talking with his wife, Blossom, Dexter relents and works with Ed, who has since merged his intelligence with his inner strength, and the two successfully build a time machine. Ed warns that changing the past does not affect their present and any changes instead create branched alternate realities. He and Stan Marsh go to the Bouchardian refugees' new home in Norway—New Bouchard—to recruit Zeke, now an repressed cynical jerkass, despondent over his failure to stop Dark Danny, and enraged to discover the disassembly of the Kids Next Door. In Tokyo, Pataki recruits Sherman Peabody, now a ruthless vigilante following the disintegration of his family.

Ed, Lincoln, Stan Smith, The Enchanted One, Neutron and his friends, and Dexter, Dee Dee travel to New York City in 1997. Ed visits the Sanctum Sanctorum and convinces the Ancient One to give him the Time Stone. Jimmy successfully retrieves the Mind Stone, but Dexter, Sheen, Libby, Carl Dee Dee and Lincoln's attempt to steal the Space Stone goes awry, (No thanks to Stan Smith) and 1997 Louise manages to escape with it. And when Dexter is contemplating on going further in the past, Stan Smith refuses to let the kids go back to the Reagan years, even when Libby reminds Stan Smith how much he wanted Christmas and all that wouldn't exist if half the universe was gone. Smith says he doesn't care as long as he's with Francine and his kids. That is until the Enchanted One points out in the Dan-Ruled future, Francine and Stan have never met due to Francine being decimated, which means Steve and Hayley won't exist. Swallowing his pride, Stan Smith trusts Jimmy, Cindy, Dee Dee and Dexter, Dee Dee to travel to S.H.I.E.L.D. headquarters in 1986, where Dee Dee obtains an earlier version of the Space Stone and Dexter reconciles with his father, Jeffery, in the process, while Jimmy and Cindy steals several Doof Particles from Heinz Doof to return to the present. Stan Marsh and Zeke travel to Bouchard in 1998, extracting the Reality Stone from Ash Reynolds and retrieving Zeke's hammer, Mjolnir. Bebe and AJ travel to Morag in 1998 and steal the Power Stone before Eric Cartman can. AJ returns to the present with the Power Stone, but Bebe is incapacitated when her cybernetic implants link with those of her past self. Through this connection, 1998 Dark Danny learns of his future success and the Kids Next Door's attempts to undo it. Dark Danny captures present-Bebe and sends past-Bebe to the present in the former's place. Peabody and Pataki travel to Vormir, where the Soul Stone's keeper, the Red Skull, reveals it can only be acquired by sacrificing someone they love. Pataki sacrifices herself, allowing Peabody to obtain the Soul Stone.

Reuniting in the present, the Kids Next Door fit the Gems into a Dexter-created gauntlet, which Ed uses to resurrect all those whom Dark Danny disintegrated. Past-Bebe uses the time machine to transport past-Dark Danny and his warship to the present, where he attacks the Kids Next Door's compound, planning to destroy and then rebuild the universe with the Gems. Bebe convinces past-Jessica to betray Dark Danny and kills her past self. Dexter, Neutron, and Zeke fight Dark Danny but are outmatched. Dark Danny summons his army to devastate the Earth, but a restored Lydia Deetz arrives with other sorcerers, the restored Kids Next Door and Guardians of the Galaxy, the armies of Wakanda and Bouchard, and the Ravagers to fight Dark Danny and his army alongside Peterson, who destroys Dark Danny' warship as she arrives. After overpowering the heroes, and killing Dexter, Dark Danny seizes the gauntlet, but Dee Dee steals the Gems back and uses them to disintegrate Dark Danny and his army, then dies from the energy emitted in the process.

Following Dexter and Dee Dee's funeral, Zeke appoints Numbah 5 as the ruler of New Bouchard and joins the Guardians of the Galaxy, while Cartman plans to search for 1998 Jessica. Neutron and his Friends returns the Reality Gems and Mjolnir to their original places in time and only Cindy remains in the past to live with Nick Dean. In the present, an elderly Cindy passes on her shield and mantle to Libby. In 2019, Stan Smith celebrates Christmas with his restored family as the enchanted one watches on.
