God Never Said That: Before Halo Wars, Halo fanon had claimed that the armor worn by Arbiters was the same exact suit that it had been through history, the successor receiving it after his predecessor had died (which is implied, but not said, in Halo 2, with the Prophets saying that the bodies were all in the mausoleum, and the armor's systems being outdated).

Henceforth, that meant the armor had been destroyed with it. Fans were annoyed, but it was later pointed out that since the Arbiter is intended to be sent on suicide missions, there would have been many cases where the armor was destroyed and/or impossible to recover.
