The only son of the Emperor, Duyere is the future embarassment to the throne. He's spoiled rotten, whiny, and is constantly complaining about his high-class upbringing, but we know he really enjoys all the cool toys and stuff his dad buys him.
Duyere is not exactly a skilled fighter either. His combat skills aren't much to write home about, and his level is usually lower than the other enemies on the battlefield. His sister Sadira is a much better fighter than him, and she seems to be much lessed spoiled and pampered than he is. Branch!
Duyere should be taken seriously in battle. Even though he's not a great fighter, he pilots the legendary Sarbelas ATAC, which makes him a formidable foe. Beware of his Gaia Slash special attack.
