One example could be a fanfiction where Harry, who is often seen as the hero, has a flaw in his 'savior' complex. He might always feel the need to save everyone, which can put him and others in danger. Another could be a story about the Weasley family. They seem like a perfect loving family, but there could be family feuds or secrets that are not known, like a character in a fanfic finding out that one of the Weasleys has a hidden magical ability that was shunned in the family, showing the family's 'flawed perfection'.
A common example in Harry Potter fanfiction is the idea of the Hogwarts houses. Each house has its own set of values that are seen as positive and in a way 'perfect'. Gryffindors are brave, Ravenclaws are intelligent, Hufflepuffs are loyal, and Slytherins are cunning. However, fanfictions might explore the flaws in these ideals. For instance, a Gryffindor's bravery might turn into recklessness, a Ravenclaw's intelligence could lead to arrogance, a Hufflepuff's loyalty might make them too trusting, and a Slytherin's cunning could become deviousness. This exploration of the 'flawed perfection' of the house ideals is quite popular in fanfiction.
Sure. In some fanfictions, the concept of pure - blood wizarding families' pride can be seen as a form of 'flawed perfection'. These families pride themselves on their pure magical blood, but in reality, this leads to a lot of discrimination and problems. For example, the Malfoys. They seem to have it all - wealth, status, and powerful magic. But their obsession with blood purity is a huge flaw. A fanfiction might explore how this so - called 'perfection' is actually a big problem in the wizarding society. Also, the Ministry of Magic is presented as this powerful and in - control organization, but in many fanfictions, it is shown to be corrupt and full of bureaucrats, which is a form of 'flawed perfection'.
