Tony Vu was a Wizard at Lancelot Castle. He is an unplayable character, who is mentioned in opening prologue of Pandemonium!.
Tony Vu was a Wizard and a drunkard, who went by the name of The Wordly One, having apparently had nothing but via the power of magic, gained everything. He hosts W.I.T.S, The Wizards in Training Seminar. Fargus, Sid and Nikki go to his seminar prior to the events in Pandemonium!. Although there's a degree of impressive magical allure about him (his entrance included transforming from smoke, to a mackerel, a buffalo and then a llama), he carelessly dropped the Ancient Wizard's Spellbook, which in turn set into motion the events of Pandemonium! when the careless wizarding trio picked it up.
