Koragg-Leanbow

Leanbow is Udonna's husband, Nick's father, and the mentor of Daggeron and Calindor. He was known for his honor and valor which Calindor resented. As a Mystic, he can assume "Ancient Mystic Mode", resembling a red/purple fiery demon wielding a sword and shield. Twenty years prior to the series, Leanbow led the other Mystics in the Great Battle against the Supreme Master of the Underworld, and his Forces of Darkness led by Morticon in order to prevent them entering the human realm. The forces of good magic eventually forced the Forces of Darkness through the Gate of the Underworld, with Leanbow personally taking on Morticon at one point. In order to keep the Forces of Darkness from escaping the Underworld, he held back the Darkness hordes from the Gate while Niella the Gatekeeper sealed both it and Leanbow into the Underworld. In this single act, Leanbow would be lost to the Forces of Darkness and Niella would use up the rest of her powers as the Gatekeeper, giving up her life force in the process.

For twenty years, Udonna and the others thought that they had lost Leanbow forever, killed in the battle that ensued behind the gate. But in reality, Leanbow had survived to reach and seal the Master - but before he fell, the Master was able to transform his enemy into his most loyal minion, **Koragg**. Though devoid of the memories of his old self, Koragg retained a few aspects of his previous life such as honor manifest in refusal to destroy a foe he considers to be weaker, citing such an action as a waste of his time and energy. In Koragg's Trial, he revealed that he felt it was important to be honorable because only an honorable warrior could be trusted to serve the Master faithfully.

This also allowed him to tame the wild horse Catastros, which became Koragg's personal Zord and gave him the ability to form the Centaurus Wolf Megazord and combine with Catastros to gain a centaur-like appearance.

Koragg was the first villain released after years of imprisonment when the seal of the Underworld was cracked by the earthquake that hit Briarwood. Upon engaging Udonna as the White Mystic Ranger, who seemed familiar to him, in battle, he bested her and stole her Snow Staff but spared her life.

Koragg often openly dueled with Morticon in a power struggle, shows contempt toward Necrolai, and bowed to no one except the Master. He has also lied to Morticon, keeping the Megazord power he stole from the Rangers for himself and claiming it was gone instead of using it to free Morticon. Despite this, however, he proved to be a loyal servant of the Master and a persistent antagonist for the Rangers. However strong the Rangers got, Koragg was always stronger, with the Master personally giving Koragg more power every day.

When Imperious succeeded in transporting the Rangers to the Underworld, during the 2-part "Heir Apparent", so he could use their Legend Warrior powers to revive the Master, Udonna attempted to stop it only to be attacked by the Master himself. After an onslaught of forgotten memories flooded his mind, Koragg came to their aid at the last second. With the evil influence that had bound him now broken, Koragg revealed himself to be none other than Leanbow, shocking everyone present. He transported everyone out of the Underworld but despite that, Nick refused to trust him and viewed his reappearance to be "one of Koragg's tricks". Leanbow revealed his past about how he was transformed into Koragg by the Master, but when he absorbed the Virus that Imperious used on the Manticore Megazord to save them, it caused a unique side effect that caused him to regain his memory bit by bit. Leanbow was quickly taken back to the Underworld and transformed into Koragg again, leading to a final confrontation between him and Nick. He was on the verge of killing the Red Ranger when Udonna intervened and revealed that Nick was, in fact, their son Bowen, and the knowledge of this freed Leanbow from the Master's spell once more. The reunion was short-lived as the Master began to tear his way out of the Underworld and Leanbow, using a spell to prevent Udonna and the Rangers from intervening, travelled back to the Underworld to fight and seal the villain once again. With his Mystic Force Fire Strike attack, he sacrificed himself to bring down the Master and nearly all of the Underworld, and returning the Legend Warrior powers to the Rangers.

While he appeared to be dead, Udonna firmly believed he "will return" and has gone on a quest to "bring him home". Her belief is confirmed in "Hard Heads" when the villainous Terror, Sculpin, scried to see what was preventing the resurrection of the Master. At the Lake of Lament, it was revealed that Leanbow is responsible for preventing the Master from being resurrected. Now Leanbow wears Koragg's violet Knight Wolf armor, but still fights on the side of good, stating "I wear the armor of Koragg, but my heart is that of Leanbow".

In "The Snow Prince", Sculpin confronted Leanbow at the Lake of Lament taunting him with images of Megahorn's rampage. Leanbow refused to leave his post, but Sculpin persisted and showed Nick being injured during the battle. Nonetheless he still refused to come out of hiding. It wasn't until Sculpin raised the stakes and dispatched Black Lance to assist Megahorn did Leanbow finally leave his post and join the Rangers in battle. Leanbow appeared in the form of the Knight Wolf Centaur and engaged the chariot-riding Black Lance in battle. Leanbow eventually destroyed Black Lance's chariot and then transformed into the Centaurus Wolf Megazord. Maintaining the upper hand, he had Black Lance under control. Meanwhile, Necrolai appeared and planted onto the Centaurus Wolf Megazord a fish scale Sculpin had given her. Leanbow returned the underworld, purposely dragging Black Lance down with him. As he departed, Leanbow told the Rangers that he was proud of them and to continue the fight.

In "Light Source," Leanbow (still wearing the armor of Koragg) hid himself deep within the depths of the Underworld within a crystal-like barrier. Since one of Sculpin's fish scales was on him, Leanbow was discovered by Necrolai, who then informed Sculpin and the other Terrors of his whereabouts. Sculpin, Gekkor and Matoombo then went to Leanbow to personally fight him and to retrieve the Master's spirit from his body. Gekkor was the first to fight Leanbow, using his lightning speed to give him an edge. But Leanbow was able to weaken Gekkor by slashing him in the stomach with his Knight Saber, then summoning a Mystic Force Fire Strike attack to weaken him. This was when Sculpin stopped Gekkor from fighting and sent Matoombo to fight him. Matoombo was able to give Leanbow an even greater challenge, using his superior strength to bring Leanbow to his knees and to shatter his shield. This left Leanbow open for Sculpin to stab him in the back with his trident and extract the Master's spirit from his body, causing Leanbow to revert to his Ancient Mystic Mode. Sculpin then used his trident to create a fissure in the ground and send Leanbow plummeting into it, but before he fell too far, Leanbow grasped an outcropping, hanging on for dear life.

In the episode "The Return," Leanbow joins forces with the Mystic Rangers. While the Legend Warriors are facing Gekkor of the Ten Terrors in battle, Udonna finds and revives Leanbow using her good magic. The Legend Warriors find themselves overpowered, and are spared from certain doom once Leanbow appears and absorbs a flame attack Gekkor fired at them. Utilizing a new red Morpher, Leanbow transforms into the Wolf Warrior, a new form in which he bears armor almost exactly the same as Koragg's with the major difference being its crimson color. After displaying this new form, Leanbow quickly defeats Gekkor.

Leanbow was forced to face Koragg again when the Master (attempting a pre-emptive strike) turned Nick into a new Koragg and used him to destroy villages in the Briarwood forest. The battle between Leanbow and the new Koragg devastated Rootcore before he freed his son by demorphing and allowing himself to be killed without a fight causing Nick's mind to break free of the Master's control. He then went with Daggeron to the Mystic Realm to face the Master, only to have his magic drained and be killed in battle. Revived by Necrolai, he joined in the final battle against the Master and helped overload him with good magic. In the aftermath, Leanbow joined his wife and son in leaving Briarwood to visit Nick's adoptive parents.

Like his wife, he was absent from the final battle of Power Rangers Super Megaforce, though his powers were employed by Silver Megaforce Ranger Orion.
