Did you ever have a crackpot theory about something in the haloverse? Perhaps something that ties together seemingly contradicting plot elements? Well, post 'em here!
For instance, I’ve been theorizing that…
The Plasma Repeater was not encountered anywhere besides Reach because it was a (failed) experimental model.
The fleet that attacked Reach was simply the guinea pig. After returning disappointing results, the Repeaters were withdrawn. This would also justify (canon-wise, that is) the Repeater’s underpoweredness compared to other Covie weapons.
