Vladek is the main antagonist of the Lego series, Knights' Kingdom II.
He was the adviser to King Mathias, but he put him in a dungeon and claimed the King had gone missing, and that a tournament would be held to determine the new king. He entered, and planned to use the power of the Book of Morcia to win and become king. However, the four Hero Knights found Mathias and defeated Vladek. Some time after, Vladek fled, and found himself in the lost kingdom of Ankoria, where he regained power by creating the Vladmask, and took over the kingdom. It was here he adopted the title of "Lord Vladek." He threated to use the Vladmask to destroy Morcia, but Sir Jayko destroyed the Vladmask and stopped him. He is the leader of the Rogue Knights and the Shadow Knights. Two of his subordinates are Dracus, a warlord, and Karzon, a weapons master. He was defeated twice by King Jayko, before being captured by him in 2006, although the details are unknown.
