Long detailed profile? I think he fits that best, for my characters.
When it comes to characters' backstories, I generally don't like making them excessively long since I like the profile to just show a neat, condensed version of their history. I never keep all their info on TH - a lot of stuff is stored off-site in private documents to keep everything cleaner.
Armin's history was hard to explain on his profile while keeping it reasonably short, so I had to include a link to one of his stories that goes into detail about it. But even though I keep the history section relatively short, he still has a fairly big profile with a long personality description, info about relationships, random trivia and so on.
