O.K. There was Hot Rod, he was given the Matrix of Lreadership. He then Became Rodimus Prime. Then Optimus Prime was rebuilt and reasurected, and given back the leadership. My assumption is because the holder of the Matrix leads.but the Matrix was used up by Optimus. so with no Matrix he was as good a leader as anyone. So did Rodimus returne to being Hot Rod? Where did "Hot Rodimus come from? Now Ultra Magnus. I read somewhere that he was Optimus Primes Brother. Is there any truth to this??
