Another plot could involve an artifact that starts to affect the Warehouse itself, creating strange glitches and anomalies. The agents have to not only deal with the artifact's influence on the Warehouse but also prevent it from spreading to the outside world. They might have to journey deep into the Warehouse's uncharted areas to find a way to neutralize the artifact.
A plot idea could be that a group of former Warehouse agents, who turned bad, come back to steal a powerful set of artifacts. The current Warehouse 13 team has to use their knowledge of the Warehouse and the artifacts to outwit the old agents. There could be a lot of action - chases through the Warehouse corridors, battles using artifacts with different powers, and a race against time to stop the bad agents from achieving their evil goals.
One idea could be a new agent arriving at Warehouse 13 with a mysterious past that turns out to be linked to an artifact that was thought to be lost forever. This new agent might unknowingly hold the key to controlling the artifact's power, causing a stir among the existing agents as they try to figure out how to handle the situation.
One idea could be exploring the backstories of the lost boys in more detail. Maybe one of them has a hidden connection to a character from the outside world. Another plot could involve a new villain coming to Neverland who has a different kind of magic that challenges Peter Pan. Also, a story about Wendy's granddaughter returning to Neverland to find a lost family heirloom could be interesting.
Another interesting plot could be Loki falling in love with a character from Once Upon a Time. Maybe he has a relationship with a princess or a powerful sorceress, and their love story is filled with magic, drama, and challenges as they come from different worlds.
A love - interest plot for Gideon would also be interesting. He could fall in love with a character from a different realm within the Once Upon a Time universe. Their relationship would be complicated by the different rules and cultures of their respective realms. They would have to overcome many obstacles, like disapproving family members or the threat of war between their two realms.
One idea could be exploring Gothel's backstory before she became the villain we know. Maybe she had a tragic love in her youth that turned her bitter. Another plot could involve Gothel teaming up with an unexpected character from the Once Upon a Time universe, like a hero who thinks they can reform her. A third option is to create a story where Gothel has a daughter of her own and we see how she raises her in contrast to how she treated Rapunzel.
One idea could be to create a story where a new character, an aspiring actress, befriends Rick Dalton and Cliff Booth. She gets involved in their crazy Hollywood adventures and helps Rick revive his career in an unexpected way, like by introducing him to a new type of movie role that suits his acting style better.
A possible plot could be that Drizella is cursed, and Henry, being the son of Snow White and Prince Charming, has a unique connection to the magic that can break the curse. They embark on a quest to find the ingredients for a potion to break the curse. Along the way, they meet old characters from the Once Upon a Time universe who either help or hinder them. They also have to deal with their own personal issues. Drizella has to confront her past and her insecurities, while Henry has to prove himself as a hero without relying too much on his family's legacy.
A really interesting plot could be that an ancient curse has been placed on both Emma's Storybrooke and Elsa's Arendelle. The curse is slowly draining the magic from both places. Emma and Elsa team up, using their combined magic knowledge and their strong wills. They travel to different magical realms to find the source of the curse and break it. They encounter many magical creatures and face various challenges that test their friendship and their magic skills.
One idea could be that Peter brings Wendy to a new magical land within Neverland that has been hidden from all others. There, they discover a new kind of fairy that has the power to grant one wish, but at a great cost. Another plot could be Wendy getting lost in a time - warped part of Neverland and Peter has to fight against an ancient magic to get her back. And perhaps they could find a way to bring some of the magic of Neverland back to the real world to help Wendy's family during a difficult time.
One idea could be exploring the origin of the Dark Swan's powers in more depth. Maybe she discovers an ancient magic that was long forgotten. Another plot could involve her forming an unlikely alliance with a character who was once her enemy to fight a greater evil that threatens their world.
Well, she could be pregnant and find out that the father of the baby is a character she least expected. This could lead to a lot of drama and character development. For instance, if it was a villain, she would have to decide whether to trust him or not. Or perhaps, her pregnancy could be a key to unlocking a new magic in the Once Upon a Time universe. It might be that the baby's existence is tied to a long - lost magic that could save the world from an impending doom. Also, Emma could be pregnant and have to go on a journey to find a special place or object that can ensure the safety of her unborn child.
