Sylvio is initially shown to have an inflated ego as a "Perfect Duelist", being selfish, stubborn, pompous, and incredibly egotistical. As such he enjoys being praised by his crew and showing off in front of everyone, although he doesn't take kindly to anyone who interrupts him. His defeat at Yuya's hands caused him to develop a grudge against him, but also caused him to develop some of his mannerisms.
