Guardian Knight

Guardian Knights (also known as the Knights of Iacon) are a subspecies of ancient medieval knight-motif Cybertronians from the planet Cybertron.

"Seglass Ni Tonday."

- The Guardian Knights' motto

Anatomy
Guardian Knights share a similar biology to other Cybertronians, except their robot modes have a medieval knight-like motif.

Powers and abilities
Guardian Knights share many of the same abilities as other Cybertronians. However, because their creation predates the Second Cybertronian Civil War, they may not always have the ability of transformation.

Select Guardian Knights can combine to form a combiner known as Dragonstorm.

Background
The Guardian Knights came into existence as servants of the alien sorceress Quintessa. However, they would come to view her as "the Great Deceiver" upon discovering she had ulterior motives for Cybertron. Stealing her AllSpark-like power staff, they set out aboard a ship into space in hopes of finding worthy allies on another world. They eventually landed their ship on Earth, in truth the dormant form of legendary Unicron. By the late 5th Century C.E., the Guardian Knights' spaceship would be partially buried beneath the hills of England. Using Quintessa's staff, they Knights created more of their number so they would have a small army that would fare against the mad sorceress.

The Guardian Knights eventually made contact with a native human "wizard" named Merlin. Learning of their home planet of Cybertron and how it was destroyed by warfare, he promised to keep their existence a secret from his peers. In 484 AD, Merlin returned to their ship and made a heartfelt plea to their red-armored leader Stormreign, seeking aid for King Arthur and the Knights of the Round Table in a dire battle against the Saxons. Judging that Camelot was proof of the worthiness of humankind, the Knights decided to render assistance to King Arthur's forces. Stormreign bestowed Quintessa's staff to Merlin, warning him that Quintessa (referred to as "a great evil") will come for it someday. As Merlin charged back into the battlefield, the Guardian Knights combined into Dragonstorm, a mighty three-headed gestalt dragon that easily wrought devastation against the enemies of Camelot.

In the battle's aftermath, the Knights of the Round Table forged an alliance with the Guardian Knights, beginning a heraldic order which would become known as the Order of the Witwiccans. On at least one occasion, the Knights charged into battle alongside Arthur's men. An unspecified time later, the Guardian Knights eventually moved their ship underwater somewhere in the Atlantic Ocean. Most of the Knights entered a centuries-long slumber, where they would guard the tomb containing Merlin's corpse and staff, the latter of which disguised itself as a wooden staff for good measure.

However, one Knight remained online to search for a prophesied "Last Knight", that would one day be chosen as a crucial player in their next fight against Quintessa. Over the next few centuries, both the Knights of the Round Table and the Guardian Knights would fall into legend and, thanks to the efforts of the Witwiccans, Dragonstorm would be misbelieved to merely be the exaggerated story of a catapult. Merlin's lineage would persist until Viviane Wembly would become the wizard's last living descendent and the only other person besides Quintessa who would wield her ancestor's staff.

Present Day
As Quintessa began moving Cybertron's towards Earth during the early 21st Century, the Talisman Knight was shot down by the Transformers Reaction Force. This Knight laid unconscious until a group of human children investigated his ship, accidentally awaken him. After saving the children from the TRF, Cade Yeager attempted to help the dying Talisman Knight to no avail, as he was too badly wounded and leaking Energon fast. Seeing Cade's compassion as a sign he was worthy of a knight's honor, the Knight presented a Knights of Iacon talisman to him. However, he refused under the impression it was a mere trinket offered as a thank you. As Cade left, the Knight used his last moments to order the Talisman to assume an insect-like form and find its new master before he finally died.

Unfortunately, the Talisman Knight's exchange with Cade was witnessed by Barricade on behalf of Megatron, who sought the talisman to find Quintessa's staff. His body was later found by TRF, which led the human government into their own search for the staff, under the pretense it was a mere weapon. Cade and Viviane would eventually be brought together by Witwiccan member Sir Edmund Burton and would learn of the Guardian Knights, their culture, and how their presence led to the formation of the Witwiccans. Following clues left by Viviane's late father, they were able to board a mode-lock Cybertronian disguised as the HMS Alliance alongside Bumblebee and Cogman.

Traveling to the Knights' undersea ship, they uncovered Merlin's tomb yet were oblivious to the staff's whereabouts due to its disguise. Attemtping to search for some more useful than a wooden staff, Cade inadvertently woke Skullitron, a Guardian Knight who decomposed during stasis to the point of his head becoming skull-like. The disoriented Skullitron immediately began attacking the apparent intruders, claiming they were in league with Quintessa. The TRF, who had been pursuing Cade and Viviane, would open fire on Skullitron while Viviane bonded with the staff, shedding its previous disguise. While being gunned down by the TRF, a severely damaged Skullitron plunged down a chasm leading into the ship's bowels towards his presumed death.

While the TRF held Cade and Viviane at gunpoint, two more Guardian Knights suddenly awakened from stasis and attacked everyone until they were both slain by Optimus Prime, who was under the thrall of Quintessa. In short order, Optimus seized the staff and escaped, though he was pursued by Bumblebee, Cade, and William Lennox in an attempt to knock him back to his senses. Just as Optimus was freed from Quintessa's mind control, Megatron suddenly stole the staff and flew off just as more Guardian Knights came online. Outraged that Optimus had been manipulated by Quintessa and put in her service via a mind-control spell, the Knights beat down Optimus one-by-one until the talisman transformed into the fabled Excalibur, which Cade used to stop an Executioner Knight's blade.

Recognizing Cade as the Last Knight, the Executioner and other Knights stopped attacking and raised their swords to chant their motto. After having his hope rejuvenated by Cade, Optimus reconciled with the Knights and rallied them to help the Autobots stop Quintessa from revitalizing Cybertron by destroying Earth/Unicron. The Knights boarded a Cybertronian ship that the Auobots commandeered from the late Lockdown and traveled to Quintessa's base, an ignition chamber located on a hanging section of Cybertron. From the ship's hull, the Knights combined into Dragonstorm and took flight against Quintessa's army of Decepticons and Infernocons, destroying enemy fighters with their fire breath and dropped Optimus into battlefield against Infernocus.

In the end, the Autobots, Guardian Knights, TRF, and company emerged victorious by neutralizing the Decepticons and stopping Cybertron from consuming Earth's energy. Soon afterwards, the Knights once again formed Dragonstorm to fly alongside the Autobot ship towards the nearby Cybertron to begin reconstruction. Unbeknownst to anyone, Quintessa escaped via teleportation and has begun a new scheme to destroy Unicron, one that involve manipulating humans whilst posing as a human herself.
