Hello guardians I know you have some characters that are Exos but do you think they are just robots or something different. I think that they are old Humans and Awoken's the reason is that they have emotions and personalities. What I mean by that there old is that if you remember the beginning of the game the speaker says human life span tripled which is about 240 years the Exos to me basically suits for people who's body became so old that it shut down or had a diseases so their brain is harvested and put into a robotic reconstruction of a body. This would explain the personalities that the Exos have and another theory the number on the side of their name like Cayde-6 or Banshee-44 that number means the amount of times their systems been wiped this could mean they their brain was digitized into data to prevent aging or disease if the data became corrupt they would have their systems wiped and reset. This my theory tell me yours or if you agree
