In the original series, Vilgax was great. He was also not over used. In fact, he only popped up in "And There Were 10", "Hunted", "The Alliance", "Secrets", "Truth", "Back With a Vengeance", "Ben 10,000", "Perfect Day", "Goodbye and Good Riddance", and "Secrets of the Omnitrix".

Out of the 48 episodes and one movie, Vilgax only appeared in ten of them. This means he was barely in 30% of the original series episodes (he was in exactly 20.2083333333333333% of the episodes in the original series).
