First, consider their motivation for using the Copy Quirk. Are they using it to become the best hero? Or maybe to prove themselves to someone? For example, if they want to be like their idol hero, they might copy only the quirks of that hero at first. Then, think about the limitations of the quirk. Maybe they can only copy a quirk for a short time, so they have to strategize when to use it. This would force them to study different quirks and opponents carefully.
If Deku had a quirk in fanfiction, it would likely impact his character development. He might have become more powerful quicker or taken on different enemies. The story could become much more action-packed or focus on different themes.
A quirk fanfic might be deemed worthless if it has major plot holes, flat characters, or doesn't add anything new or interesting to the existing quirk universe. Also, if it's full of grammar mistakes and spelling errors, that can really detract from the reading experience.
In 'The Healer of UA', Izuku's healing quirk is more complex. It requires him to concentrate and visualize the injury being healed. He can also transfer some of his own stamina to the injured to speed up the process. This makes his quirk not only about physical healing but also about his own sacrifice and determination.
First, focus on her insecurities. Despite having a powerful Titan Quirk, she might still doubt herself like the original Izuku. She could worry about losing control and hurting those she loves. Show her working hard to master her Quirk in private, constantly pushing her limits.
Well, it's hard to say for sure. You'd have to look into the background and the creator's statements to determine if it's based on actual events. Sometimes what seems like a true story could have a lot of creative liberties taken.
