Nickname for Gil-galad

[Darth Fingon]

I need a nickname/codename for Gil-galad in one of my stories. The nickname will probably be given by Glorfindel and should probably fall in line with the other two nicknames already established in the story: Bird (Elrond) and Judge (Erestor). Any suggestions?

(Also, I suppose a nickname for Glorfindel would be required as well.)

Spear or Thorn (Gil-Galad)
Crocus (Glorfindel)

Sorry, perhaps not too original...

Head? As in him being the king and all, and also at least to me a rather intelligent individual.
