Elrond

Elrond Peredhil, or Half-Elven, is a Canon Character from J.R.R. Tolkien's Lord of the Rings. He is the lord of Rivendell and a master of lore and healing. He convened the Council that decided to send the Fellowship to Mordor.

In LOTR he is kind, good and wise.

In badfic he is grumpy, hidebound, prejudiced and often a Designated Misogynistic Bastard, and often married to Galadriel (in Movieverse fics where the author has not really been paying attention). He often pushes Aragorn into marrying Arwen, despite this being almost directly contrary to both book and movieverse canon.

In badslash he is usually paired with either Legolas or Glorfindel (depending on whether or not the badficcer knows about Glorfindel).

He is the Lust Object of a good number of Agents, including most famously, Agent Jay Thorntree.
