70-30% HP: Switches to bipedal stance, and will periodically alternate back to quadrupedal stance. In its bipedal form, Omega is vulnerable to physical damage and extremely resistant to magical damage.
<30% HP: Final form. It will always remain in its bipedal form at this point, although it is different from the bipedal form used earlier, and employs different attacks and defenses. In this form Omega is resistant to both physical and magical damage, but the resistance is less potent than of the previous forms (approximately 50% damage taken from all attacks)
Omega is the 24th and final letter in the modern Greek alphabet. Because of this, the word is often used to denote the last, the end, or the ultimate limit of a set, in contrast to Alpha, the first letter of the modern Greek alphabet.
