No offense but I dont think we should be comparing Embry, an original concept and character, to Nagito Komaeda or Kokichi Ouma. While I too can see the resemblance, it's a little annoying (personally, since I don't talk for the creator) to see a unique character like Embry get compared to characters like Nagito or Kokichi.
Keep in mind I love Nagito, Kokichi and Embry, it's just my personal opinion.
