The Icemon Cometh - S1.E10

Rika is being followed by a mysterious icy force, which frightens her. Not wanting to admit it, she refuses help when Renamon offers to protect her. Renamon is dismissed, and feels hurt by what Rika said to her. While Rika is vulnerable without Renamon's protection, IceDevimon then appears and captures the girl, taking her into an alternate dimension, an icy tomb where he has sealed his Digimon victims. The fallen angel Digimon offers Rika to be his tamer, but she refuses. Renamon comes to Rika's rescue and digivolves to Kyubimon but fails to stop him. Guilmon and Terriermon attempt to help Renamon and Rika, but are trapped by IceDevimon's freezing ice powers. Finally, Henry manages to free them, and Guilmon takes over the battle. Using extra speed and wings, Guilmon traps IceDevimon's head in the ceiling and destroys him, absorbing his data. However, the traumatizing fear caused by the fight causes Rika to claim she hates all Digimon, and she and Kyubimon go their separate ways.
