Figwit is a fan name for one of the elves at the council of elrond b/c he doesnt seem to have any official name. He doesnt speak a single word and is only seen for about 3.5 seconds, but there are whole fansites about him and discussions who looks better, Legolas or Figwit (even I must say Legolas does!)
There is even a site dedicated to the LordofthePeeps-version of Figwit!!
