Giddianhi is the main antagonist of Samuel and the Sign. He is the leader of the Gadianton Robbers. He is first shown lending money to a Nephite named Eli. When Samuel the Lamanite starts climbing the stairs of Zarahemla, Giddianhi sneaks a bag of money inside the belt behind Samuel's back (both figuratively and literally) and frames him for theft, and the wicked Nephites throw him out. Five years later, Giddianhi breaks into Nephi and Timothy's house and rips off the curtain, gloating that the prophecy was a lie. Nephi tells Giddianhi the sign will come. Giddianhi says he hopes it does for Nephi's sake, and plans to kill every believer for "following a false prophet." He and his Gadianton robbers form an army, and he welcomes a weak and faithless man. On the day that the sign is supposed to come, Giddianhi and his men surround Nephi, Timothy, and all of the believers (even Eli), and the sun sets, and it gets dark. Giddianhi gloats, "So much for you and your 'God'!" He and his men start to kill him with swords, but then it gets light. Because it is a light night, Giddianhi drops his sword and runs off.
