Sentinel Knight
From Power Rangers Universe
The Sentinel Knight is the original protector of the Corona Aurora. Millennia ago, after Flurious and Moltor had attempted to steal the Crown, the Knight took it upon himself to separate the Crown and its Jewels. This was done in order to stop anyone from getting the power again. The guardian scattered the crown and the five jewels on a distant, uninhabited planet. That planet, those many millennia ago was Earth.
He appeared to Andrew Hartford after he had found the Corona Aurora, and explained to him about the evil that would come and what to do to protect the crown. He again appeared in order to convince Will, Dax, Ronny and Rose that they were the world's only hope.
The Sentinel Knight made another appearance in "Face to Face II" to congratulate the Rangers on their victory and retrieval of the second gem of the Corona Aurora.
In "Once a Ranger", it was revealed he had battled and imprisoned Thrax, the villainous son of Rita Repulsa and Lord Zedd. When Thrax returned and disabled the Overdrive Ranger's powers, the Sentinel Knight summoned five veteran Rangers and repowered them so they could temporarily defend the jewels in the current Rangers' place. After Mack retrieved the sword Excelsior, he gave it to the Sentinel Knight so that no one could use it to harm him and its power restored Sentinel Knight back to his physical form. After being restored to physical form, he swiftly destroyed Thrax. He has since been capable of transforming into the powerful Sentinel Sword weapon.
Thanks to additions by Rose, it is possible for the Sentinel Knight to merge with Mack and turn him into the Red Sentinel Ranger, creating a "Battlizer". He is still sentient in this form and is able to talk to Mack.
The Sentinel Knight is voiced by Nic Sampson
