Battle Against A Machine is a battle theme in EarthBound that plays when battling Giygas's stronger minions. It is heard very rarely until Ness returns to Onett and inside the Cave of the Past.
In Mother 1 + 2
it is slightly lower in tone and less techno-sounding than the original. It is considered one of the more notable instances of the GBA's inferior audio compression.
