Lyle Tiberius Rourke

Commander Lyle Tiberius Rourke is the main antagonist in Disney's 2001 feature film Atlantis: The Lost Empire. He was the Commander of a previous mission to Iceland where he assisted Milo Thatch's grandfather in locating the Shepherd's Journal. He is voiced by James Garner.

Role in Atlantis: The Lost Empire
In 1914, he is hired by Preston B. Whitmore in another expedition to Atlantis with his second-in-command Helga Katrina Sinclair. After escaping from a robotic Leviathan in the city's gates, Rourke and the team are taken to the King's room, where he asks to spend the night. After Milo and Kida swim while learning about Atlantis's heart, they re-surface only to discover that Rourke became mercenary. After Kida is fused with the Heart, he takes off with Helga and his soldiers, but Atlantis's citizens, Milo and the rest of the team chase him to a volcanic crater. Rourke attempts escaping in a balloon, trying to shoot the Atlantians with his Lewis Gun, trowing Helga out to "relieve weight", while fighting Milo with an axe. He gets scratched by a crystal shard and turns into a statue, but still manages to move towards Milo. He is finally destroyed when Milo overweights the metal structure he's standing, crushing Rourke in the balloon's propeller.

House of Mouse
Roark appeared in Donald Wants to Fly. Watching Kida fly above his head in quiet awe. He is notably the only villian to not appear on Mickey's House of Villians.

Trivia

 * Rourke is similar to Sir Ector from The Sword in the Stone, Governor Ratcliffe from Pocahontas, and Judge Claude Frollo from The Hunchback of Notre Dame, as all three are soliders/army commanders and are trained in combat or lead an army into battle against the Heroes.
 * Rourke is also similar to Stromboli from Pinocchio as both are thought of as good guys at first, but then they reveal their true colors by betraying Milo Thatch and Pinocchio.
