You may call me... the Forever Knight.

– Forever Knight introducing himself to LaGrange.[1]

The Forever Knight is a tech construct who appears in Ben 10. Over the course of season 3, he recruits enemies of Team Tennyson to join his cause.


The Forever Knight wears metal armor partially inspired by medieval European knights. It is augmented with alien technology that affords him great maneuverability and speed that would otherwise be inhibited by the clunkiness of the armor. When damaged, the yellow strips of light fade and turn off. He has yellow lighting on his helmet, and he wears a red cape along with his armor. He also bears the Forever Knight symbol on his chest, resembling the classic Forever Knights. Beneath his mask, his host is a Caucasian man with no facial hair.

After being lost through time, Forever Knight was reduced to being just the helmet of his armor.


The Forever Knight is brash and arrogant. He spies on Team Tennyson and their many enemies, including Simon Sez, Charmcaster, Vin Ethanol, Billy Billions, and Kevin Levin, deciding which ones are worthy enough to join his cause.

Forever Knight feels disgraced whenever Kevin disobeys his orders, and makes fun of him and Ben for being children in possession of uncontrollable power.[2]

Forever Knight probably has a strict vetting process for bodies and only wants those in peak physical condition.[KT 1]


Your Omnitrix is helping me locate something. I've been tracking alien signals across time and discovered three instances where alien life has attempted to contact Earth, one of which will happen momentarily here in ancient Egypt. The plan is simple -- Go back in time and prevent any contact from happening.

– Forever Knight explaining his plan to Ben.[3]

His goal is to go back in time and prevent alien signals from contacting Earth. Throughout Season 3, he tests Team Tennyson's enemies to determine those he needs for this goal. He needed Ben and Kevin to power his time gateway due to both of them having Kineceleran forms in their Omnitrixes, Charmcaster to stabilize the portal with her magic, Vin Ethanol to monitor Ben and Kevin's progress, Billy Billions to provide his drones as security, and Simon Sez to help activate the gateway.

Kevin and Forever Knight The Bentathlon.png

Forever Knight offered a chance to make Kevin better. Kevin turned down the Knights offer twice until he threatened Gwen. Out of all Forever Knight's recruits Kevin is assigned the most missions. Kevin seems himself as one of Forever Knight's best recruits and made the Knight popular by creating a video cam of him during their partnership.

However, Forever Knight only sees Kevin as a "cheap Tennyson knock-off" and a useless pawn. He also believes that with out him, Kevin has no one.[4]

Forever Knight did not hesitate to try and take Kevin out after he disobeyed him.[5] He also did not worry about harming Kevin when raising the steaks during a gladiatorial fight between Kevin and Ben.[6]

While they are in a time portal, the Knight demands Kevin to make himself useful for once and bring him Ben. Kevin then sacrifices getting trapped in time by kicking the Knight through the time portal, leading them both somewhere unknown.

Ben Tennyson

Forever Knight kept a constant watch of Ben, manipulating im through a series of events. Similar to Kevin, Forever Knight required Ben's unique abilities to enact his plan. However, this would require him to cause a rift between he and his family.



During an unknown time, a tech construct was created with a consciousness that lives inside the "Forever Knight" helmet and rides around on people like a robot parasite. It has probably been around for several human lifetimes, using it’s robotic intelligence to build wealth[7] and push it around with shell companies.[KT 2]

Ben 10

The Forever Knight has been watching Ben Tennyson ever since the beginning of the series. He first appeared in Omni-Copped, when he instructs Steam Smythe to intercept the Tennysons and observes his defeat at the hands of Ben.

In This One Goes to 11, the Forever Knight sees footage of a defeated Kevin, remarking that Kevin would be an even better candidate than Ben.

In King of the Castle, the Forever Knight reached out to Kevin after his battle with Ben, only for the boy to turn him down out of claiming that he does not need help.

In Don't Touch, the Forever Knight battled Ben over a katana only to get his helmet damaged and knocked over the horizon by Humungousaur. The Knight appeared to be smiling at the exact moment Humungousaur threw him off far away with his tail, possibly showing that he was trying to see if Ben was worthy of being recruited.

In Welcome to Zombozo-Zone!, Zombozo tried to impress the Forever Knight in hopes of joining up with him. The Knight remarks that Zombozo was never a king as the latter is arrested, suggesting that he has no intention of bringing Zombozo into his team.

In Bridge Out, the Forever Knight orchestrated a traffic jam by forming a blockade. After Simon was stopped, the Knight called off the blockade, knowing that Simon can be useful; Simon would eventually join the Knight off-screen.

In Charm School's Out, the Forever Knight recruits Charmcaster to his cause after rescuing her with his jet.

In Franken-Fight, the Forever Knight scolds Kevin for failing to defeat Ben due to his romantic interests in Gwen only for Kevin to destroy the transponder hidden on his padlock necklace.

In Buggy Out, the Forever Knight sent Kevin to steal the Rustbucket for its technology, though the boy ended up failing due to interference from Ben and Glitch. Kevin then attempted to use Glitch to run over the Tennysons, forcing the Knight to attack Kevin in retaliation, though his jetpack as blasted by Heatblast.

In Introducing Kevin 11, Kevin officially joined the Forever Knight's side, having abandoned his pride in favor of jealousy towards the Tennysons.

In Forever Road, the Forever Knight offered to help LaGrange by giving him a remote that would sabotage Ben's transformations and orchestrated a race in the desert in which the victor would become the next member of his team. Although the remote was destroyed and LaGrange was defeated, the Knight was able to instead recruit Vin Ethanol in the racer's place.

In The Night Ben Tennyson Came to Town, the Forever Knight continuously torments Ben to the point where he decides to exploit Ben's delusions towards his family refusing to trust him.

In Prey or Play, the Forever Knight invites both Ben and Billy Billions to a theme park called Adrenaland. In the end, Billions joins his team.

In The Bentathlon, the Forever Knight abducts the Tennysons and has Ben fight against Iron Kyle, Queen Bee, the Alien Chef trio, the Ground Hawg Gang, and Kevin in a series of gladiatorial matches. Ben is ultimately the victor of each and every fight and is rescued by Gwen and Max.

In Heads of the Family, Ben (while his head is on Kevin's body) receives a phone call from Forever Knight, instructing him to report back.

In Roundabout: Part 1, Ben finally joins the Forever Knight out of having enough of Gwen and Max refusing to trust him, to Kevin's confusion. With his assembled team, Forever Knight infiltrates a laboratory in Switzerland and constructs a time gateway. Ben is chosen to accompany the Knight after he defeats Kevin, Charmcaster, and Billions. When Gwen, Max, and Phil came to the lab in search of Ben, the Knight has the rest of his team deal with them while he and Ben venture through time.

In Roundabout: Part 2, Ben immediately turns on Forever Knight out of not wanting the Knight to prevent the Omnitrix from making its way to Earth. Forever Knight overpowers Ben while fighting him in Ancient Egypt, Renaissance Italy, and Max and Phil's youth. However, Forever Knight's plan ultimately fails due to interference from Gwen (who followed them to help Ben) and Kevin (who is interested in payback for the Knight neglecting him). Pursing the children through a time portal leading towards the present, Kevin sacrifices himself to trap the Knight.

In The Monsters in Your Head, it is shown that Kevin is somehow able to escape the time gateway, leaving Forever Knight's current whereabouts (and when-abouts) unknown.

In Cosplay Day, it is revealed that Forever Knight came out of the still-open time gateway long before Kevin did. In his parasitic helmet form, Forever Knight infiltrated a cosplay convention to find a new host. After a few run-ins with Gwen and Max, he commandeers Steve and uses his influence as a judge to abruptly end the competition and force everyone to go home to cover his getaway. Omni-Kix Cannonbolt finally recognized the Knight's helmet as the genuine article and chases after Steve until the helmet holds Max hostage. Fortunately, Omni-Kix Cannonbolt and Gwen are able to save their grandfather and trap the helmet, who is then taken away for inspection by Phil.

Powers and Abilities

Forever Knight is a skilled martial artist, as shown besting Four Arms, Diamondhead, and Shock Rock in combat.[3] Forever Knight is very agile and quick, he was able to fight off XLR8 with little to no struggle.[8]

The Forever Knight is made of alien technology. He can possess and take control of anyone his helmet latches onto.[9]


The Forever Knight uses an energy shield and mace as his primary weapons. The mace can also turn into a spear, flail or sword.

The Knight occasionally uses a drone to observe Team Tennyson and their enemies.[10][5]

At his mansion, the Knight has a robotic servant that performs much of the manual labor.[11]


There is a limit to how much damage Forever Knight's suit can take. His suit can also power down when sustained enough damage.

Forever Knight can be contained within Dark Matter's crystals.


Ben 10

Season 3

Season 4


  • Forever Knight is a tech construct of indeterminate origin. He finds people who will let him assume control of their bodies until he retires them to go live comfortably somewhere.[KT 2]
    • The guy seen in Don't Touch is just some guy who signed up to let Forever Knight pilot his body until it wasn’t an optimal host anymore, in exchange for whatever his share of the cash was when he retired and got replaced with a new body.[KT 3]
  • Despite being a new individual created for the reboot series, the Forever Knight shares many similarities with the Forever Knights organization from the classic timeline:
    • Just like how Driscoll assembled the Negative 10, the Knight spends the majority of season 3 observing and/or recruiting various enemies of Team Tennyson, including those who previously made episodic appearances during season 1.
    • The Knight's ultimate goal of keeping aliens from arriving on Earth echoes the Forever Knights' goal in Ultimate Alien and Omniverse, in which they tried to rid Earth of all aliens because they saw them as "unearthly".
  • A potential Kevin 11 series spin-off would explain how Forever Knight and Kevin escaped the time tunnel after the events Roundabout: Part 2.[DR 1]
  • The existence of the Forever Knight was first discovered through the app Ben 10 Moji, which contained stock artwork of him available as stickers.
  • The idea of the Forever Knight being an individual rather than an organization was a reused concept from the original series.[DR 2]
  • The interior of his helmet is similar to Iron Man's.
  • Forever Knight is one of the very few opponents that Ben Tennyson has not beaten in direct combat.
  • The idea of Forever Knight being sentient technology was the general idea for the character the crew was working on when they wrote The Night Ben Tennyson Came to Town and Cosplay Day.[KT 4]
  • Kelly Turnbull pitched an episode where the Forever Knight is taken to wherever Phil stores his alien tech before taking over the shapeshifting creature. However, the episode was scrapped because the series was winding down by that point and the episode itself was not in the cards.[KT 5]
