Boss

There are many boss enemies in the Mother games.

In EarthBound Beginnings, bosses are few and far between, and the main distinction between them and other enemies is that they are encountered only at specific locations. In EarthBound, bosses guard many locations, including all Your Sanctuary locations. Mother 3 has a boss at the end of each chapter except Chapter 6 which contains no enemies; additionally, all of the Seven Needles have a boss encountered nearby. When encountering bosses in EarthBound and Mother 3, the entering battle sound is based on the one heard in Mother.
