You can destroy basically anyone in FFVIII by junctioning 100 magics like ultima, flare, meteor and full life (triple for speed) to your stats.
If you get 255 vit and 255 spr, (which u gotta user the vit bonus and spr bonus before your level 100) then almost every attack will do less than 1000 or even below 100. Final Form Ultemecia is the only one who can lower your health down to 1.
