Theirs was a story of sacrifice and loss, making Udonna and Leanbow a very unique couple in Power Rangers. Shortly after the birth of their son Bowen, an attack from the Master's minions forced the Mystic Wizards into battle. To preserve his family and friends, Leanbow ordered the Gatekeeper Niella to seal the Gates, locking himself and the evil armies into the Underworld. Udonna survived, thinking her husband lost; only the Master's evil power wiped Leanbow's memories and transformed him into the dark warrior Koragg. Fortunately for the Mystic Force Rangers, Leanbow's noble heart influenced even his darkest deeds as the Master's most loyal warrior, as he never destroyed Udonna or the Rangers after several sound defeats. Ultimately, it was in a battle against Udonna that his memories were finally restored, revealing to the Rangers and his wife what had happened.
