If you think about it you can incorporate any character into a game. Even Final Fantasy if you look past the aesthetics. Think flexiblity.

Jonny Quest - artificer or thief
His partner could be some sort of wizard.

Guinan from Star Trek - blue mage or white mage.

"Friends" could easily be knights or paladins.

What you're referring to is what 'job' should one be. It's not a matter of what one you'd like to see all the time, but maybe what job is correct for someone real/imagined.

In final fantasy or any fiction/non-fiction there are plenty of characters of any kind in combat/non-combat rolls or both. Cid is a great example.
