Amuro's fate differs between the novelization of Mobile Suit Gundam and official timeline. In the novels, Amuro is killed by Char's 300th Autonomous Newtype Corp before the Battle of A Baoa Qu even ends. The official timeline mark Amuro's death 13 years later in the Second Neo Zeon War, which is reflected in the original novels Hi-Streamer and Beltorchika's Children. However, in the animation and in the related games, both Char and Amuro are listed as MIA.
So which one shall we trust? :S
