It could be due to their eating habits. Oliver might consume a lot more food to keep up his energy for all those Quidditch practices. He needs high - calorie foods to fuel his body. Percy, on the other hand, might be more focused on his books and not eat as much. So over time, Oliver could end up being much heavier.
Perhaps in the fanfic's universe, there's some sort of magical reason. Maybe Oliver was under a spell that made his body denser or something. And Percy didn't have any such influence. This could result in Oliver being much heavier. It could also be related to their family genetics in the fanfic world. Oliver's family might just have genes that make them heavier built compared to Percy's family.
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.
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.
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.
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.
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.
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.
It might not have a huge impact on their relationship on the Quidditch team. They are both dedicated to the sport. Oliver's weight might not matter much when it comes to flying skills. Harry could still be the star Seeker, and Oliver could focus on his role as Keeper. They would respect each other's abilities and work together towards winning the Quidditch Cup, regardless of the weight difference.
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.
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.
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.
Oliver might have a training regimen that includes a lot of core strengthening exercises. This would help him balance better while flying, given his heavier build. He could also practice with heavier brooms to get used to the extra weight. Harry's training would likely be centered around reaction time. He'd want to be able to quickly change direction in the air. So he might do a lot of drills where he has to respond to sudden signals or movements.
