"Sentinel Knight!"
―Sentinel Knight's Roll Call[src]

The Sentinel Knight is a very powerful mystical warrior from ancient times and the guardian of the Corona Aurora.


After Flurious and Moltor tried to steal the Corona Aurora and were subsequently cursed, the Sentinel Knight hid the crown and its five jewels throughout the planet Earth. His spirit returned after a few hundred years to urge that Andrew and his team of Rangers protect the crown from impending forces. He once battled and imprisoned Thrax, the son of Rita Repulsa and Lord Zedd.

When Thrax disabled the Overdrive Rangers' powers, Sentinel Knight summoned five veteran Rangers and repowered them so they could temporarily take the current Rangers' place. After Mack retrieved the sword Excelsior, he gave it to Sentinel Knight so that no one could use it to harm him. Excelsior restored Sentinel Knight, and fused with him, granting Sentinel Knight a new physical form.

After being restored to a new physical form, he swiftly destroyed Thrax. He has since been capable of transforming into the powerful Sentinel Sword weapon. Thanks to modifications by Rose, Sentinel Knight was able to merge with Mack to become the Red Sentinel Ranger. When the Corona Aurora was successfully retrieved, the Sentinel Knight took his original form, but is still able to combine with Excelsior. Using the completed Corona Aurora, the Sentinel Knight restored Mack to life and even made him human after he was seriously damaged, the Sentinel Knight recognising that Mack had a true heart even if he was 'only' a machine.

The Sentinel Knight was not shown to have fought in the final battle between the Legendary Rangers and the Armada.

Up until his battle with Thrax, the Sentinel Knight donned a royal black-robed attire. He maintained this appearance as a spirit guiding Andrew Hartford and the Overdrive Rangers.

Excelsior changed Sentinel Knight's corporeal form by merging itself unto him, creating armor. By combining with Excelsior, Sentinel Knight becomes extremely powerful. In his Super Mode, he can grow to the size of Zord, in order to fight giant size monsters.

Sentinel Sword


Excelsior is a legendary sword of great power, and the only weapon capable of destroying Sentinel Knight. Sentinel Knight uses Excelsior as his personal weapon despite this knowledge, when he's in his normal form. The sword became imbued with the Sentinel Knight's spirit and persona. When Sentinel Knight fuses with Excelsior, his powers are enhanced tremendously.
