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, often a Designated Misogynistic Bastard, and also often married to Galadriel (in Movieverse fics where the author has not really been paying attention). He frequently pushes Aragorn into marrying Arwen (or vice versa), 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, who was actually able to get an autograph from Elrond during the eighth TOS mission while in disguise. Despite this, though, he doesn't seem to actually know about the PPC.
