A portkey can be any seemingly harmless object, like a football or a dolphin. However, a person cannot be a portkey, because if that person were to touch themself, they would constantly be transported to different places.
"Sir, can, like, a person be a portkey?"
"No, that's absurd. If they were to touch themselves, they'd constantly be transported places"
"No, that's absurd. If they were to touch themselves, they'd constantly be transported places"
