This idea surrounds Master Chief’s body and armor.
This will add on to one of my other posts about the armor that I think he should wear.

The armor itself should look like the Didact’s but it should be green with blue lights and the helmet should be more like the Mark IV, V, or VI. Like I said in my other post the armor should make him much stronger and much faster than he is in his Mark VI. This will be due to the immense power the suit has.
From what I’ve been reading it seems that the UNSC has found the Bornstellar Didact’s consciousness on Onyx. I believe that this consciousness should be given to the Master Chief The way the Ur-didact gave his consciousness to Bornstellar. Now since the biology of Forerunners is different from humans in that they evolve into their roles I would think that this would affect his body in a strange way. I would believe that his body would also continually evolve the way Bornsteller’s did but not as radically. This would also give 343 a reason to have two campaigns around two different characters. Bornstellar and Master Chief. The Bornstellar part would be around Master Chief trying to understand the memories that have been given to him. Master Chief’s campaign would obviously be the main campaign. This would also tie into the fact that many people think that Halo 5 will be similar to Halo 2.
This could also help to flesh out the Forerunners. the memories could show times during the Human Forerunner war and the Forerunner Flood war. This would also allow them to bring back the Flood.
