It depends on your perspective. Some might consider it new as it brings in new elements and developments. But in a broader sense, it still builds on the existing Scott Pilgrim universe.
Definitely. 'Scott Pilgrim Takes Off' draws inspiration directly from the comic. It retains many of the key elements and storylines from the source material.
Scott Pilgrim is the central character. He's a young man on a journey of self - discovery, especially in the realm of love. Ramona Flowers is also a main character. She's the object of Scott's affection and has her own mysterious past. There are also Scott's friends like Wallace Wells, who adds a lot of humor to the story with his sarcastic remarks and laid - back attitude.
One interesting storyline could be Ramona and Scott going on a parallel adventure in a dream world. In this fanfiction, they might face their inner fears and insecurities represented as strange dream creatures. It would add a new layer to their relationship and character development.
Obviously, Scott and Ramona themselves are great to focus on. Their relationship is the core of the story, so exploring different aspects of it, like their first meeting from Ramona's perspective or Scott's thoughts during their toughest times, can make for great fanfiction.
