Gríma Wormtongue is one of the Blind Bag characters in LEGO Dimensions 2: The Rise of Enoch, from the Lord of the Rings franchise.
Gríma was the counselor of King Théoden of Rohan. He secretly joined the service of Saruman and weakened Théoden and his kingdom by working as a spy. He used his voice to keep a spell intact while Saruman possessed the king, causing the people of Rohan to call him Wormtongue.
In The Two Towers, Gandalf breaks Gríma's control of Théoden and releases the king. Before Théoden could kill Gríma, Aragorn stopped him. Instead, Gríma was exiled from Rohan with only a horse which he rode to Orthanc with.
While with Saruman, Wormtongue gave him important information, including Théoden's plans to leave Edoras for Helm's Deep and revealing the heir of Isildur. Wormtongue, shocked with surprise, watched as Isengard was attacked by Ents and flooded with water from a dam close by. After this time Gandalf, Aragorn, Legolas, Gimli, Eomer and Théoden rode to confront Saruman. When they arrived at the walls of Isengard, they found Merry and Pippin at the foot of the battle.
Grima, called "Worm" by Saruman, was shot down by many Hobbit arrows once he stabbed Saruman to death in the Shire. Grima was the last casualty in the War of the Ring.
