* Andy from ''Fanfic/CalvinAndHobbesTheSeries'' eventually became this after initially being TheGenericGuy. He's usually the only one who can keep everyone in the group from arguing.

* Even though [[HaruhiSuzumiya Kyon]] and [[MahouSenseiNegima Chisame]] have had their backstories revised when they're brought into TheEmiyaClan, they retain their personalities perfectly. Everyone else in the Clan is insane, weird, perverted, or otherwise, while these two struggle but usually succeed to keep their sanity amidst a household where random explosions, EldritchAbominations, and harem antics are considered normal.
