I'm not that brave so willpower is out of the question. My favourite Lantern Corps is the Sinestro Corps because of they're awesome team members and because they represent fear, my favourite emotion. Fear best represents me, and if I did have a Sinestrto Corps ring, I'd go around murdering Green Lanterns with my fellow Corps members.
    

 
  
 
 
 
 
 

 

 

 
 
IN BLACKEST DAY, IN BRIGHTEST NIGHT, 
BEWARE YOUR FEARS TURNED INTO LIGHT, 
FOR THOSE WHO TRY TO STOP WHATS RIGHT, 
BURN LIKE HIS POWER...SINESTRO'S MIGHT!
