Perhaps in the fanfic, the fact that Oliver Wood is heavier is related to his role as a Quidditch captain. He might need that extra weight for stability on his broom during rough games. It could also be part of a sub - plot where there are challenges or competitions that are affected by his weight. For example, there could be a magical scale that measures more than just physical weight but also something like 'leadership weight' and Oliver's heaviness in that sense gives him an advantage in certain situations.
Well, it could be just a random physical characteristic given for comical effect. Maybe the author wanted to create a contrast between Oliver Wood's more solid, perhaps muscular build compared to Percy Potter. It might also be used as a way to emphasize Oliver's presence or strength in a humorous way.
In this fanfic, Oliver Wood being heavier could potentially symbolize his more down - to - earth nature. If Percy is seen as more of a bookish or cerebral character, Oliver's extra weight could represent his connection to the more physical aspects of the wizarding world, like Quidditch. It could be a way for the author to play with the stereotypes of different character types within the Harry Potter universe.
Another aspect could be related to his age and growth pattern. If in the fanfic's universe, Oliver has gone through a growth spurt earlier than Harry and has filled out more. His body could have developed more mass in terms of both muscle and some extra fat as he entered adulthood or a more mature stage of growth before Harry did.
Maybe it's because Oliver Wood is more muscular. He's a Quidditch player and all that physical training might have built up his muscle mass more than Percy, who is more into academic and administrative work. So the difference in their body composition could lead to Oliver being much heavier.
One possible reason could be different lifestyles. Oliver, being so focused on Quidditch, might have a diet that consists of more hearty and filling foods to keep his energy up during practices and games. Percy, on the other hand, might be more into lighter, more 'intellectual' meals as he is often buried in books and administrative tasks. This difference in diet could lead to Oliver being heavier.
Perhaps a fanfic where there's a spell gone wrong that makes Oliver Wood gain weight. Percy, with his knowledge of the wizarding rules and regulations, tries to find a way to reverse it. And Potter, well, he could be the one who encourages Wood not to give up. The story could explore how Wood copes with this new physical state, his insecurities, and how his relationship with Percy and Potter changes during this time.
I'm not sure specifically which fanfic this refers to. But generally, if in a fanfic Oliver Wood is heavier than Percy, it could be shown through physical descriptions. For example, when they are standing side by side, the author might describe how Oliver's frame is broader and more solid - perhaps he fills out his Quidditch robes more fully compared to Percy. Or when they are participating in some physical activity like climbing stairs, Oliver might be shown to be a bit slower or more out - of - breath due to his extra weight.
Oliver Wood would be in a state of shock. He'd feel self - conscious about his heavier weight as his identity has been so tied to being an athletic Quidditch player. Percy would approach the situation with his typical efficiency. He'd start researching in the library or asking around for any spells or potions that could help. Potter, on the other hand, would be more about the emotional support. He'd tell Wood that his worth isn't just in his physical abilities. He'd share his own experiences of facing challenges that seemed insurmountable at first. The interactions between these three characters would be a mix of practicality, empathy, and determination.
Well, it could lead to some friendly teasing. Oliver might be a bit self - conscious about his weight and Percy could make light - hearted jokes about it, which would strengthen their bond in a way. Or it could be the opposite, and Percy's comments could cause some tension between them.
The weight difference could also lead to a more balanced friendship. Oliver's heftier build might mean he is more stable, both physically and emotionally. Harry, who might be seen as more slender or wiry, could rely on Oliver's sturdiness in different ways, like when they are working together on a project or facing a common enemy. Oliver's greater mass could be a symbol of his reliability in their relationship.
It could lead to some friendly teasing. Percy, being a bit more proper, might be slightly amused or bemused by Oliver's heftier build. Oliver, on the other hand, might not care much and just see it as part of who he is.
Perhaps in the fanfic, the weight difference is symbolic. Oliver Wood's greater weight could represent his groundedness, his connection to the more physical aspects of the wizarding world like Quidditch. Percy Potter, if he's more into academic or bureaucratic matters in the story, might be presented as lighter in a sense of being less 'tethered' to the physical world. It could be a creative device to show how different their worlds and focuses are within the narrative of the fanfic.
