Guardian Forces

Final Fantasy VIII introduced Guardian Forces, a summoned creature of much more importance than those previously found from Final Fantasy II through Final Fantasy VII.  Some of them are very familiar, but this time they're alot more important to a character's vital statistics and abilities.  Junctioning with a GF gives a character unique powers, and the combinations allow for almost limitless customization.
