Big Hero 6 vs. the Forces of Evil 3: Relative War  (or simply Big Hero 6 vs. the Forces of Evil 3) is an upcoming 2018 American animated superhero comedy-drama crossover film. It is the third installment of the Big Hero 6 vs. the Forces of Evil series. Similar to the previous installment, Miraculous Squad, the film crossovers with the Nickelodeon animated series, The Loud House, although it features characters from a couple of films and TV shows.

The film is set to premiere on Disney XD and Nickelodeon on November 26, 2018.

Synopsis Edit

Star, Marco, and Mr. and Mrs. Diaz go to Royal Woods, Michigan for a spring break vacation. Star and Marco then wander off and meet a family known as the Loud family, whose children are nice to the two. Soon, when the Loud children reveal their true colors to Star and Marco and capture them, he contacts the Big Hero 6 to save them. Hiro comes up with a plan to save Star and Marco and stop Lincoln and his family.

Plot Edit

The film starts as Timon and Pumbaa from The Lion King are shown watching the opening act of Bee Movie in a dark theater when Timon suddenly uses a remote control to fast-forward to where his favorite scene (where Barry B Benson says "You like jazz?") is at. Pumbaa argues that the film shouldn't go out of order and asks Timon to instead watch one of three films: Finding Nemo, Big Hero 6 vs. the Forces of Evil 3, or the YouTube video known as "The entire Ice Age pentology but every syllable is replaced with the entire Toy Story trilogy but every second that the color green is in the frame is replaced with every video ever uploaded on YouTube but every 10 seconds every episode of The Simpsons plays but every word with a vowel is replaced with Bee Movie but everytime a bee is shown every episode of SpongeBob is played backwards". Timon and Pumbaa start fighting over control of the film until they agree that the film they'll watch should be Big Hero 6 vs. the Forces of Evil 3. Throughout the rest of the film, it is occasionally interrupted to have Timon and Pumbaa comment on whatever is happening.

After helping Ladybug and Cat Noir save the day and defeating Hawk Moth, Star and Marco receive A+'s on their papers. As the bell rings, it turns out it is the last day before spring break. As Marco and Star say goodbye to their friends, they proceed to home, where his parents are planning on a vacation. Star and Marco are curious what place the family is going on vacation, so Mrs. Diaz tells the two that they're going to a town called Royal Woods, in Michigan, for the spring break vacation.

The next morning, Star contacts Hiro and the Big Hero 6 and tells them to protect Mewni from the forces of evil, and they agree to defend Mewni. Then, Star, Marco, and his parents get in the car with the suitcases and arrive at the airport, where they get on the plane, and it starts flying to Royal Woods, Michigan. Soon, when they arrive, Star cheers for the plane, but Marco drags her and his parents decide to go to the park. Star and Marco wander off and they arrive at a house, where they meet Mr. and Mrs. Loud, who are happy because they are visitors. The two parents then introduce Star and Marco to the kids (Lori, Leni, Luna, Luan, Lynn, Lincoln, Lucy, Lola, Lana, Lisa, and Lily). Star creates a portal to prove that she is actually a princess from another dimension, then the kids are wowed by Star. Star decides to spend some time with the kids, and Marco watches Bee Movie. Later, Star and Marco tell the Loud kids where they live.

Meanwhile, Mr. and Mrs. Diaz find out that Star and Marco are missing, so they contact the police to go find the two. Back at the Loud house, Lincoln and his sisters go to the basement and proceed their secret plan, but Star and Marco overhear their conversation, they go down the basement, where Lori and Leni tie them up, and Star demands answers. Lincoln then explains that they wanted to take over their home because the Loud house is falling apart. Marco uses Star's interdimensional scissors to get himself and Star out of the ropes. Lincoln, upset, orders his sisters to attack Star and Marco, so they get tools and wooden planks to attack Marco, while Star tries to blast Lincoln, but he throws explosive cards. Before the cards can explode, Marco grabs the cards and launches them back at Lincoln, who then dodges them. Luan successfully hits Star and Marco unconsciously by using a wooden plank.

Soon, Star and Marco wake up in Lynn and Lucy's bedroom, where Lincoln orders Luna to use her electric guitar to bother Star and Marco. However, Marco manages to get out of the ropes just in time and goes to the kitchen, where he contacts Hiro and tells him about the Loud family. Hiro, shocked, decides to come up with a plan.

We cut to Hiro, who has a meeting with the Big Hero 6. Everyone gives him ideas, but Hiro tells them he has already came up with a plan which involves getting help from people from different dimensions, such as Pink Sheep, Purple Shep, Shrek, Barry B. Benson, Darth Vader, and the Angry Birds. Hiro then contacts the people he was talking about, and soon they arrive from portals. Hiro and the Big Hero 6 test out the people by sending in Gene from The Emoji Movie, and Barry tells Gene by saying "You like jazz?", causing him to explode to death. A few hours later, the Big Hero 6 and their alliance open a portal and go to Royal Woods, Michigan.

At the Loud house, Lincoln discovers that Marco has escaped, so he and his sisters go after him. They succeed in recapturing Marco, and Lincoln tells him that if he tries to escape again, Lily will poop on Star. Lincoln sends Marco and Star into the basement, and then orders his sisters to torture them.
