Normal: "A fiend encased in thick armor. Its strength, defense and other attributes are all formidable. It can't be having much fun with all that armor weighing it down." Oversoul: "A fiend encased in thick armor. It now also uses magic, courtesy of oversouling. That's three more yucky points for the ugly giant." — Scan
Stalwart is an enemy from Final Fantasy X-2. A relatively powerful enemy, and even more dangerous when in Oversoul. It is best to hit him with the party's strongest attacks. Having Shell or Reflect when in Oversoul is ideal, as it has a large arsenal of magic at its disposal, including the deadly Holy.
