Yes, you can be demoted by an admin with a higher rank than yours. The only admin this is not true of is the wiki owner, and that's because they're the highest ranked admin on any given wiki. The only way they can be demoted is if Wikia staff does it, and Wikia staff will typically not remove a wiki owner from power unless the individual has been inactive for an excessively long period.

By excessively long, I'm talkin' a year or more.
