Ammoron
(Pronounced Am-or-on - not "a-moron" even though that's funnier)

A Nephite traitor and brother to Amalickiah who becomes king of the Lamanites after his brother's death.   He knows his cause is not just but carries on the war with the Nephites.   Like his brother, he is also slain by Teancum.
