WikiKing
A WikiKing is a troper that, like most feudal lords, claims certain work and trope pages as their own. They do tend to be knowledgeable about the pages they assume dominion over, but they often acts as though other WikiFauna should respect their right to have the final say.
There are some benevolent WikiKings, who claim dominion if only to weed out content that would be disturbing, creepy or outright wrong that would be counter to the goals of the ATT community at large, but power can corrupt, and even the benevolent can often fall prey to becoming tyrants.
They can be friendly and useful members of the wiki, but they often run afoul of WikiKnights who often challenge their excesses.
