The TriStat RPG (role-playing game) system is a product of [Guardians of Order], Incorporated. Its premise is that all characters are based on three primary statistics: Body, Mind, Soul; along with a number of abilities, defects, and skills. This is in keeping with more Eastern traditions, and stands apart from the Western tautology of dividing an object or person into many different qualities (strength, quickness of hand, looks, sociability, sagacity, whatever).
There are various TriStat games, differentiated primarily in what size die is used when rolling tests (as in combat). All are point-based systems, meaning one spends points to buy abilities; this is considered by proponents to be a more inherently "fair" system than the level-based designs of D&D or RIFTS (among others), in part because it allows for a relatively clear means of knowing just how powerful a character is.
Frostbyte's player appears to favor a d12 or d20 based version of TriStat (twelve or twenty-sided dice). Most likely, this is the d20 version currently sold as an alternative to Hasbro/WotC/TSR's branded D20 system. That person may wish to alter this paragraph.
Echo's player favors the d6 version of TriStat known as Big Eyes Small Mouth, or BESM. This version focuses on anime themes, though as Echo has found, any role-playing game may be used to support any theme or genre; the simpler the game, the easier it is to use for a non-obvious theme.
These characters have been "written up" for TriStat rules. The die size and rulebook are noted in parentheses for convenience.
Addendum: Think of this more as fans statting up characters from something they like than actually something that'll be used. Think doing stats just because it's fun to figure them out. ;) There're plenty of instances of this out on the Web, Techni-Muyo GURPS stats and whatever.
