Ness is a young boy from Onett, characterized by his love of American things, such as baseball and steak. He also possesses psychic abilities strong enough to affect cosmic events, such as altering the course of the future. Ness' mother cooks for Ness and his friends, and allows them to rest. His father supports him over the phone by recording his progress and depositing money into his cash account. His sister, Tracy, stores items for the group, by way of Escargo Express. Ness is primarily a supportive PSI user rather than an attacker. Unlike his appearance in the Super Smash Bros. (series) series, Ness is unable to use PSI Fire, PSI Thunder, PSI Magnet, or PSI Starstorm, although they were added into his move list to allow for a wider arrange of attacks. He is, however, capable of using the PSI Flash move, which is capable of instantly defeating foes at the zenith of its power, regardless of their defenses, as well as a myriad of other status effects if the attack connects. Ness' only offensive PSI ability is a psychokinetic wave named for whatever the player chose as their "favorite thing" in the beginning of the game, the default name being PSI Rockin.

In the anime, it is revealed that Maira, a former Pawn, became a Bishop by gaining the ÄRM Vaqua. He is not given a backround in the manga. Maira is a black-cloaked masked man who takes pleasure in engulfing and digesting people with Vaqua. Vaqua is a blue/green slime-like Guardian ÄRM with one eye. Maira is first seen watching the War Game battle between Ginta Toramizu and Garon. During the second round of the War Games, Maira reappears as a fighter for the Chess Pieces. He has the last of the battles in that round, and goes up against Dorothy. Maira is quick to falsely judge Dorothy's power, though he easily destroys one of her weaker Guardians and stalemates another. Dorothy, however, calls back this one to bring about her favorite, Toto, which eats Maira's Vaqua. Maira, now ÄRM-less, begs Dorothy for mercy. Dorothy, however, doesn't do as such and has Toto eat Maira as well, becoming the first casualty of the War Games.
