Ness is the silent main protagonist of EarthBound, and is analogous to Ninten and Lucas in their respective games. He greatly enjoys baseball; not only are most of his weapons various types of baseball bats, but he can also equip several baseball caps. In the EarthBound Player's Guide, he is said to wear a special baseball cap with his favorite team's logo on the front.
Lucas is the Central Character of Mother 3, out of Seven Main Characters total. He is from Tazmily Village. He is the gentle twin of Claus. He usually uses sticks and baseball bats as his primary weapons, along with his powerful and strong signature PK Love power, which is the ability to pull the Seven Needles in order to wake the Dark Dragon which is sleeping underneath the Nowhere Islands.
The Mr. Saturn are a species in EarthBound and Mother 3 and serve as the unofficial mascot for the trilogy. They are strange, possibly extra-terrestrial life forms who reside in both Eagleland's Saturn Valley and the Nowhere Islands's Saturn Valley in EarthBound and Mother 3, respectively. They are characterized by huge noses, four whiskers, and a single hair with a small red bow. They are generally very peaceful and generous, offering free stays at the hotel and coffee. They speak Saturnian, and erratically use the words "boing," "ding," and "zoom" at the ends of their sentences. The Japanese font is said to be inspired by the handwriting of the young daughter of EarthBound's designer, Shigesato Itoi.
Of Mr. Saturn, Itoi has stated that the race is the symbol of innocence in EarthBound. The Mr. Saturns are often said to have no gender, but in Mother 3 a Mr. Saturn exclaimed "Girl, am girl" which, though it could mean a multitude of things, is one of several signs pointing to the idea that the Mr. Saturn have genders. Their coffee apparently has psychoactive properties, since both Ness and Lucas each receive a message set to a surreal and psychadelic background upon drinking some Saturnian coffee.
Their village has round homes which resemble flying saucers and strange furniture, such as Automatic Teller Machines which bounce up and down in place and resemble Mr. Saturn. Some of the Mr. Saturns' preferred foods are "peanut cheese bars" and "piggy jelly", goods that can be purchased in the Saturn Valley shop. These foods are the main diet of the Mr. Saturn.
