Digimon Tamers - Season 1 Episode 12 Divided They Stand

Rika and Renamon struggle as they contemplate whether or not they need each other to become powerful. Renamon is attacked by a swarm of hostile Flybeemon, but she defeats her enemies and then considers what Impmon told her about becoming powerful without the aid of a human tamer. Later, she is attacked by Harpymon, and finds herself rendered powerless. Renamon is about to be destroyed, when Rika appears and desperately stabs Harypymon with a tree branch to stop her from harming Renamon, allowing Renamon to escape destruction and digivolve into Kyubimon just in time. Kyubimon easily destroys Harpymon but doesn't absorb her data, as she realizes that Rika's friendship as her tamer is truly what she needs to become powerful. Afterwards, Kyubimon and Rika make amends.
