Irongron

Irongron was a 13th century robber baron, who had taken control of a castle in Wessex while the nobleman who owned it was away.

Biography
When Irongron and his troops saw a bright light in the sky, Irongron immediately claimed it for his own, naming it "Irongron's star". He and his men followed the "star" as it fell to earth. The "star" was actually a Sontaran spacecraft, which disgorged it's occupant, Linx, upon landing. Irongron immediately challenged Linx to a fight, naming him Star Warrior. Linx turned the fight down, and instead bargained with Irongron, asking him for a place to hide his ship and the means to fix it, in return for some of his advanced weaponry, an offer which Irongron readily accepted.

Irongron quickly grew to despise Linx for not coming when he wished and repeatedly insulting him. He also hated Edward of Wessex, who possessed much more then him in the manner of quality food, drink, and weapons. His men captured a scribe from Edward, whom Irongron ordered to be put in the dungeon, where he later died. While outside his castle the day after, Irongron was shot at by an archer called Hal, sent by Edward. Hal was captured, and Irongron challenged him to face a robot knight, a gift from Linx. Hal won, but only when the Third Doctor shot the control device. When the Doctor was running out of Irongron’s castle after creeping around, Irongron tried to kill him before he escaped. Irongron failed as Hal disarmed him.

Soon after, Irongron launched an attack on Edward's castle, which was quickly repelled through the efforts of the Doctor, forcing him and his troops to retreat. Upon his return Irongron was given a second robot knight by Link. Irongron tested the knight by fighting it and losing to it, only to discover the Doctor was wearing the suit all along. Irongron had his men capture the Doctor, using him as targetpractice for his men. The Doctor escaped, however, with the help of Sarah Jane Smith.

Sarah Jane, disguised as a serving wench, had earlier infiltrated Irongron's kitchen, and drugged the food. Once ingested, the food quickly put Irongron and his men to sleep. Irongron awoke before the rest of his men, discovering Hal attempting to disarm them. Throwing aside Hal, Irongron went after Linx, accusing him of treachery, and attacked the Sontaran. Linx then killed him. (DW: The Time Warrior)
