The Omega Borg (Last Borg in Mother) is an enemy found on Mt. Itoi in EarthBound Beginnings. Its defense is high compared to the other enemies, excluding the Star Miner. It utilizes PSI attacks but also uses offensive attacks as its primary weapon. It is completely entirely better than the Megaborg and the Giga Borg. If Ninten and his team's level isn't high enough to easily handle the enemies, then it is recommended to avoid the Omega Borg, as it sometimes appears alongside other enemies as well.
