That's an easy question!  Hands down it has to be 
Ferio, who is also one of my favorite male 
characters across all of anime.  A guy with a 
sword bigger then himself, helpful, likes to joke 
around, gorgeous...

I'm always looking for really nice Ferio cels, 
here is one from the 1st season, 2nd season and 
from the OVA ^_^
