Lord Finfwack

"Where will he end?!" Lord Finfwack was the ruler of Locket and the main antagonist of Thomas the Great Discovery. He is voiced by Alan Rickman.

Appearances
In Thomas the Great Discovery, Finfwack exiled all of the poor people from his land, forcing them to take refuge in Sir Topham Hatt's yard. Back at his castle, Finfwack tortured the Gingerbread Man into revealing the location of the other fairytale folk which he has not captured or exiled yet. Just as Gingerbread Man was going to reveal what he knows, Lord Finfwack decides to plan a tournament to see which knight would be worthy enough to embark on a quest to retrieve a crown for him. However, Sir Topham Hatt, who traveled from his yard to Locket accompanied by Thomas to ask Finfwack to move the fairytale creatures off his land, disrupts the tournament. Then Finfwack switched the tournament, declares Sir Topham Hatt the champion of the tournament and gives a proposition to Sir Topham Hatt: if Sir successfully completes the quest to rescue the crown and competes in a spelling bee for him, Finfwack will restore Sir's land back to normal, before the fairytale creatures took refuge.

Sir Topham Hatt and the engines successfully saved the crown from the hamster. Soon, the gang journey onward to Locket. After having resolved severed ties with his brothers, the engines crash the wedding in hopes of preventing the spelling bee. There, Thomas confesses his love to Sir Topham Hatt. But then, Finfwack laughs at Thomas, which prompts the crowd to laugh with him, then he orders them imprisoned. With it seeming that Finfwack finally prevailed, Henry, riding on the hamster's neck, crashed through the glass window. Thomas and Finfwack fight and Finfwack falls to his death, defeating him and saving Locket from his tyranny.

Thomas 4-D
In Thomas 4-D, Finfwack returns as a ghost and he has Thelonious kidnap Sir Topham Hatt so he can slaughter him, make her his ghost servent, and make him King of the Underworld. He also sends a stone hamster from the graveyard to murder the engines, but Henry's Hamster comes to their rescue. During a chase scene (reminiscent of the Death Star scene in Star Wars), the stone hamster loses its wings and falls to a presumed demise. After hamster rescues Thomas, the engines Sir Topham Hatt and Thelonius from falling to their demises over a waterfall, she eliminates Finfwack by breathing fire at him, reducing him to several miniature Finfwack heads, which disappear for good.

Thomas: Cousin Nevill
Henry has a daydream about what he could do if he had a vacation. After imaging himself dancing to "Good Vibrations" by The Beach Boys, He imagines Lord Finfwack interrogating the Gingerbread man from the first film then acts confused why he imagined it.

Thomas: Gordon Returns
Even though he is not seen nor mentioned, in Gordon's other universe, the Magic Mirror belonged to Gideon and so Finfwack never owned it and never knew about Fiona. Therefore, she was never saved by one of his knights. He was supposed to appear in the film, but it was dropped at the last minute.

Thomas's Scary Stories
In Thomas's Scary Stories, the characters go to the Locket Castle to tell frightening stories. It turns out the entire lordship of Locket was deserted and in disrepair after Finfwack's demise, thus making it seem all the more terrifying. Dennis fakes a haunting by Lord Finfwack to frighten the engines.

The overall appearance of Locket in Thomas's Scary Stories may have been altered to a more scary and Halloween scale for the purpose of the special itself.

Video Game Appearances
In Thomas and Tillie: The Video Game PC version, while not physically appears in the game, Finfwack's face is seen on a training dummy that Thomas uses to practice fighting.
