Leanbow

Leanbow is Udonna's husband, Bowen's father, and the mentor of Daggeron & Calindor.

He was known for his honor and valor, which Calindor resented. As a Mystic Wizard, 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 Mystic Wizards in the Great Battle against Octomus, the Supreme Master of the Underworld, and his Morlocks - the undead hordes under Morticon - in order to prevent them entering the human realm. The forces of good magic eventually forced the Morlocks 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 Morlock 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 Octomus - but before he fell, Octomus was able to transform his enemy into the 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.

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 Octomus, 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 Ranger when Udonna intervened and revealed that Nick was, in fact, their son Bowen, and the knowledge of this freed Leanbow from Koragg once more. The reunion was short-lived as Octomus 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 Octomus once again. With his Mystic Force Fire Strike, he sacrificed himself to bring down Octomus and nearly all of the Underworld.
