The character interactions are often the most interesting part. For example, when characters from different Marvel groups meet, like Iron Man and Captain America from the Avengers meeting Wolverine from the X - Men. Their different personalities can lead to some really fun dialogue and tense moments.
Another option could be Bonnie and Rebekah. Rebekah is a strong - willed female vampire. The two of them could start as rivals, perhaps competing for the same magical item or having different views on how to deal with a supernatural threat. But as the story progresses, they could develop an unexpected friendship or more, which would make for an engaging fanfiction.
A really cool one is 'Avengers and Doctor Strange: Mystic Crossovers'. It focuses on how the Avengers team up with Doctor Strange. The fanfiction delves deep into the magic side of the Marvel Universe and shows how the Avengers' physical strength and Strange's magic combine to face a powerful dark force. It has some great plot twists and keeps you engaged throughout.
Perhaps in the fanfiction, Bonnie is in a situation where she needs the protection of the Originals. As she stays with them, she starts to influence their way of thinking, and they in turn introduce her to a different side of the vampire world. This interaction could lead to a romantic relationship between Bonnie and one of the Originals, while also facing challenges from the vampire and witch communities.
I think maybe some heartwarming cartoons showing the daily lives of old people in Oregon could be popular. Like stories about their hobbies or community activities.
The future of cartoon future cars could be very innovative and eco-friendly. They might have unique shapes and advanced technologies for better performance and safety.
