This has been on my mind for a while and maybe this warrants a thread. I know the question is a bit obvious "No shit its a really big human" but I'm starting to think things might be more complex than that seeing as how there are actual humans that are over 20 feet tall and giants who look to be a little taller than Doflamingo. There are also different from different places, for example all the viking inspired giants come from Elbalf but seem to be the most unrefined as oppose to wherever Saul is from. I'm thinking there's a biological difference but due to what we'eve seen so far giants don't really have anything special about them. Again yeah the size can be seen as a special trait but like a said there can be really "small" giants and yet really big humans so I ask again, and I hope I'm coming in clear : What is a giant?
Apologies if this thread is looked upon unfavorably, but I'm not trolling I'm very serious. Even though that sounded like a troll statment, i assure you I'm serious.
