Robo Knight

"I am Robo Knight: Protector of the Environment, Guardian of the Earth!"

- Robo Knight's Roll Call

Robo Knight is the first robotic Sixth Ranger of the Mega Rangers. He also transforms into the Lion Zord which forms the Lion Mechazord.

A Knight to Save the Day
Robo Knight is one of the earliest creations of Gosei, along with the Megaforce Zords. Robo Knight was originally meant to be the protector of Earth, built centuries ago by Gosei with powerful weaponry, sharp reflexes, the fearlessness of a lion and an unwaivering commitment to his mission to protect the environment.

However, Robo Knight became dormant, and he did not awaken until the 21st century, when the planet itself somehow willed him to awake and fight the Warstar Army.

When Robo Knight finally awoke, his primary directives put him in direct confrontation with the Warstar, but centuries of deactivation took a great toll on his advanced Artificial Intelligence: such as memory loss, acting cold, aloof and distant towards the rangers and Gosei.

Furthermore, the advanced technology used for programming Robo Knight's A.I. make nigh-impossible a mere reset to his earlier directives and memories: as such Gosei himself. Gosei suggested to have Robo Knight's memories restored by having the rangers gain his trust and win his alliance.

Gosei Grand Megazord
He reappears in Prince Takes Knight to battle Psychotick, who Vrak sent in an effort to drain Robo Knight's power and reprogram him to serve the Warstar Army. During the initial battle, Robo Knight avoided several attacks without regard to whether or not the humans nearby were safe. The Megaforce Rangers struggled to protect the people Robo Knight was carelessly endangering.

Vrak's plan begins to work, as Robo Knight was captured, trapped in an energy-draining cage. Tensou was unable to get a fix on the knight's position, so the Rangers are forced to search on foot. Troy alone is able to locate them, and his speech about teamwork and loyalty causes Robo Knight some confusion. Psychotick was unable to hold the rest of the Rangers at bay, who rejoin the battle, but are defeated quickly. Robo Knight manages to reverse the power drain and escape, defeating Psychotick and forcing Vrak to retreat. When Psychotick grows, Robo Knight orders the Rangers to stay behind as he summons the Knight Brothers, a Zord duo with which he combines to form the Gosei Grand Megazord. After he defeats Psychotick, Robo Knight maintains that he needs to work alone to minimize errors in his mission, but demonstrates that he may be coming around through his use of the term "bad guy."

Learning How To Cooperate
Though Robo Knight stated he would work alone, he aided the Rangers in the battle against Shadow Serpent. When he witnessed Troy trying to restrain Shadow Serpent, Robo Knight dismissed that Troy was the problem. He stated that the weakness in humans is that they care too much about each other. Sometime after the battle, Troy meeted up with Robo Knight about a plan in having the Rangers be used as bait against Shadow Serpent, and have Robo Knight make the surprise attack. Though he refused, he went on with the plan anyway when he saw the rangers working together as if they "were like gears in a motor". After the battle, Robo Knight stated that they have much to learn and that they should collaborate.

Later on when he saw Rotox, Robo Knight viewed him as one of his own. Taking advantage of this, Metal Alice talks Robo Knight into siding with her. She stated that the humans are the true danger ans that they must be enslaved to stop pollution. He was left to think about it.Then Robo Knight left the scene, thinking on who to side with. After awhile of thinking, he joined the Rangers in fighting against Rotox, stating that the good humans do outweighs the bad. After the battle, Troy stated that he officially became the 6th Ranger of the team.

Self Sacrifice
Sometime before the Armada arrived, Vrak disabled the Rangers and Robo Knight's Morpher during a battle. The Messenger then arrived to the scene to finish the Rangers off. However Robo Knight was able to divert his internal energy to recharge his morpher, so it was still functional. When the Messenger fired his laser beam attack against the Power Rangers, Robo Knight jumped in the way and fired his elemental attack as well, overpowering and incapacitating the Messenger,draining the energy from his attack in the process. Then Robo Knight transferred the last of his power to the Rangers' Morphers and gave his Morpher and Blaster to Troy. Suddenly he collapsed powerless to the ground, seemingly meeting his end. When the Rangers returned to where he collapsed they noticed drag marks and assumed he dragged himself off to an unknown location. During the invasion, Troy runs off to search for him.

Super Megaforce
Troy takes an effort to find the missing Robo Knight, but with no luck. Even after the first battle with the Super Megaforce powers, Troy asks himself, "Where are you, Robo Knight?" Soon after joining the other Mega Rangers, Orion begins to have visions of all the other Sixth Rangers, including Robo Knight. Orion is also later able to tap into his power when in Super Megaforce Gold mode.

Vrak manages to find Robo Knight and took him to his underwater lair. Vrak didn't have the proper resources to revive him. He found out that the only way to revive Robo Knight is to use a Sixth Ranger power as Robo Knight is a Sixth Ranger himself. Vrak waited until Vekar's death to capture Orion. Vrak had Orion's energies drained into Robo Knight. Now as Vrak's servant, Robo Knight devoted himself to him.

Each time Vrak plotted his moves, Robo Knight attacked the Rangers. Each time the Rangers convinced him that he to break free from Vrak's control, he stated that Vrak is the only one who knows the truth. While Drill Horn fought Emma, Gia, Jake and Noah in one battle, Troy fought Robo Knight. Troy managed to free Robo Knight from Vrak's control. Robo Knight wanted to make up for the evil deeds he did under Vrak's control.

Robo Knight went into Vrak's underwater lair to save Orion. Vrak and Robo Knight had a brief battle until the lair was being blown up. As the lair was being blown up, Robo Knight manages to save Orion by transferring his life force into him. Though Robo Knight didn't escape while Orion did, he now lives within Orion.

Robo Knight briefly revived in the battle against the X Borgs with all the other rangers. He appears alongside Troy who greets him as an "old friend".

Lion Mechazord
Combined with a dump truck, Lion Zord becomes Lion Mechazord. Lion Mechazord can perform laser attacks, shooting an energy beam while unleashing a torrent of missiles. Lion Mechazord's final attack is Knight Power Charge, Victory Strike.

Lion Mechazord forms the main body of Gosei Grand Megazord and chest and feet of Gosei Great Grand Megazord, with Robo Knight himself forming the head in both formations.

Additional Combinations

 * Lion Mechazord can combine with the Knight Brothers Zords to form Gosei Grand Megazord.
 * Lion Mechazord can combine with the Knight Brothers Zords and Gosei Great Megazord to form Gosei Great Grand Megazord.

Ranger Key
The Robo Knight Ranger Key is Robo Knight’s personal ranger key. This key along with the other 14 Official Sixth Ranger Keys are seen lining the Command Center's interior walls. This key is mainly used by Orion (Super Megaforce Silver) who uses it to fight as Robo Knight.
