The show revolves around Ben Tennyson, his cousin Gwen, and their grandfather Max. During the start of their summer camping trip, Ben goes stomping off into the woods after another fight with Gwen, whom he is not happy to have along on the trip, and finds an alien pod on the ground. When he examines it, he finds a mysterious, watch-like device, called the Omnitrix, stored inside. The device attaches permanently to his wrist and gives him the ability to transform into a variety of alien lifeforms, each with their own unique powers, quite similar to DC's Dial H for Hero comic. Although Ben realizes that he has a responsibility to help others with these new abilities at his disposal, he is not above a little superpowered mischief now and then.
In the first season, the plot mainly focuses on the villain Vilgax, an evil alien warlord who wants to use the Omnitrix to conquer the galaxy. Injured at the start of the season, he sends various drones to get the Omnitrix until he is healed. After he is fully healed, he attempts to retrieve it himself, only to be stopped by Ben, Gwen and Max. Furthermore, it is hinted throughout the season that Max knows more about aliens than he lets on, culminating in the revelation that he and Vilgax had fought previously. A more subtle plotline involves Ben being forced to "grow up" and learning to use the Omnitrix responsibly, with particular emphasis on that point in the episode "Kevin 11".
The second season mostly follows a "villain of the week" format. The few plot-centric episodes focus on Kevin, a super-powered teen with the power to absorb different types of energies, who meets Ben in the first season. Having inadvertently allowed Kevin to absorb the Omnitrix's ability during their first meeting, Kevin serves as an antithesis to Ben. A sociopath, Kevin eventually morphs into a hideous amalgam of Ben's original ten forms and blames Ben for it. Vilgax also returns in the finale, teaming up with Kevin in the hopes of succeeding where he failed originally. Again, he fails, and both he and Kevin are trapped in an alternate dimension, the Null Void. Another important event during this season is the destruction of Ghostfreak, one of Ben's original ten forms. Having escaped from the Omnitrix, he plans to possess Ben and use the power of the Omnitrix to begin his own legacy of conquest. However, he is defeated and destroyed by Ben.
The third season has a similar yet darker plot layout. Its few plot-centric episodes focus around aliens styled on traditional horror monsters that Ben acquires as new forms through their contact with the Omnitrix. Purple-colored lightning, caused by a teleportation device created by the Frankenstein-esque alien Doctor Vicktor, heralds their appearance. Vicktor, in turn, is loyal to Ghostfreak, who is resurrected later in the third season. He plots to shroud the earth in darkness with the use of a corrodium beam projected from a space station and expanded across the earth using a transmitter in New Mexico, thus allowing him to be at full power and rule over the planet. His attempt, however, is thwarted by Ben; he dies once more from direct exposure to the sun, but not before his DNA is readded to the Omnitrix.
The fourth season revolves around Ben's last adventures as summer vacation ends. The few plot-centric episodes revolve around the leader of the Forever Knights organization, Forever King, and his plans to deal with the Tennysons himself. He gathers many of Ben's enemies to serve as members of his group, the "Negative 10" to both battle the Tennysons and steal a powerful energy from the Plumber base at Mount Rushmore. Ben eventually defeats the Forever King, destroying the Mount Rushmore faces in the process, though it is implied that a hologram is used to recreate the faces. Ben 10: Secret of the Omnitrix is set shortly after this point.
The series' final episode shows a possible take on Ben's return to normal life following the end of his summer vacation, and ends with the reveal of his secret powers to his father and the general public, after a final climactic battle with Vilgax. The film Ben 10: Race Against Time portrays a similar situation, the difference being that Ben fights an original character created for the film and his secret remains safe

Cannonbolt

While most Tortugans simply prefer to roll up and play possum, they can also be extremely aggressive, releasing a powerful chemical blast. Tortugans are able to transform into devastating projectiles strong enough to penetrate solid steel.
Wildvine

Florauna are quick to regenerate by spreading seeds yet they need steady exposure to sun and water in order to thrive. They are particularly sensitive to cold, and when denied their energy source they will quickly dry up, wilt, and perish."
Benwolf



While Benwolf maintains most of Ben's personality, he must constantly battle the urge to devolve into the Loboan's savagery.
In addition to sharp claws and pointed fangs Loboan emit a concussive howl strong enough to knock down enemies. This mega amplification is accomplished by spreading their quadra lobed muzzle into four separate parts.

List of characters in Ben 10
Ben Tennyson Ben fills the role of leader after Max disappears. The Omnitrix has been recalibrated, giving him access to a new set of alien heroes. Over the past few years, Ben has matured dramatically.
Gwen Tennyson Now 15, Gwen is much more proficient with her powers, able to manipulate energy through thought alone as opposed to spells. Gwen is much calmer and grown up, nowhere near as fiery or sharp-tongued as she was five years ago, although she does occasionally bicker with Ben.
Kevin Levin A former nemesis of Ben, 16-year-old Kevin reforms and joins the Tennysons on their quest to repay Magister for saving him from the Forever Knights. While not as psychotic as he once was, he still desires revenge for his time in the Null Void at first, though he puts it aside to help stop the Highbreed. His abilities now allow him to absorb the properties of any solid matter he touches.
Max Tennyson Max is a retired member of the Plumbers. He disappears while investigating the Highbreed plot, leaving only a few cryptic messages for Ben to find. He is briefly reunited with his grandchildren in "Max Out", but sacrifices himself to destroy a Highbreed factory at the end of the episode.
Highbreed The Highbreed believe themselves to be the purest of all species, and intend to cleanse the galaxy of impure lower life forms. Earth is their next stop.
DNAliens Hybrids of humans and alien drones that serve the Highbreed, the DNAliens are able to disguise themselves as humans using special identity masks.
The Forever Knights Alien arms dealers, the Forever Knights have worked in secret ever since their formation in the Middle Ages. Unaware of the Highbreed's true intentions, the Forever Knights are currently in business with them.
Ben 10: Alien Force forms
In the sequel series, Ben 10: Alien Force an older Ben gains ten new alien forms from a recalibrated Omnitrix.[36] The aliens were designed by mixing and matching the powers of the aliens from the original series.[37] Every alien introduced thus far is voiced by Dee Bradley Baker.
Alien X
Alien X is an alien set to be introduced in "X Equals Ben Plus 2". He has reality warping powers.[38]
Big Chill
Big Chill is a moth-like alien whose wings and antennae can "fold" up, giving him the appearance of a phantom; his appearance is reminiscent of the cryptid known as Mothman. He can become intangible and invisible, and can breathe freezing vapor. He can also freeze the objects he passes through at his discretion. He first appears in "Kevin's Big Score" to chase down Kevin after he stole the Rustbucket.
Brainstorm
Brainstorm is a genius crustacean alien with the ability to control electrical energy and project force fields around himself and others through thought. He can also fire bolts of electricity. In this form, Ben speaks with much greater diction and with a British accent. He first appears in "Pier Pressure" to battle Ship. Brainstorm is Ben's first accidental transformation in the new series, and the first alien that Ben thinks up a name for (Ben simply shouts the names of the other aliens upon using them).
Chromastone
Chromastone is a Crystalsapien from the planet Morotesi. Chromastone is a living crystal, able to absorb energy (like a conductor) and channel it into multi-colored laser blasts or simply allow it to pass through him harmlessly. He also has super-strength and is nearly invulnerable to harm. He first appears in "All That Glitters" to stop a group of zombified schoolgirls.
Echo Echo
Echo Echo is a small white alien whose body is a living amplifier. He can scream at ultrasonic frequencies capable of overloading machinery and stopping projectiles in mid-flight. He also has the ability to duplicate himself, not unlike Ditto, but different in that the clones aren't linked in any way. By combining these two aspects, Ben can create the "Wall of Sound", where he and his clones can redirect projectiles back to their source by bouncing them off of strategically placed clones.[39] He first appears in "Ben 10 Returns" when Ben fights a robotic dragon controlled by the Forever Knights.
Goop
Goop is a shape-shifting green blob that weighs 200 pounds. Goop's slime is controlled by a UFO-like machine over his head, which is also where Ben's voice comes from. The UFO can cause the slime to take any shape, and even hover off the ground. However, if the UFO and the slime are separated by even a short distance, the slime will go inert until the UFO recollects it. Goop first appears in "The Gauntlet" when Ben battles an alien robot.
Humongousaur
Humongousaur is a Vaxasaurian, a humanoid dinosaur alien from the planet Terradino. Standing at about twelve feet tall, Humongousaur has great strength and vast resistance to injury. He also has the power to increase his own body size and mass, growing up to 60 feet in height. His strength increases as he grows, and his dinosaur features become more pronounced. His first appearance is in "Ben 10 Returns" when Ben fights a swarm of DNAliens.
Jetray
Jetray is a Aerophibian (a play on 'aero' for air and amphibian) from the planet Aeropela. Jetray is a manta ray-like alien capable of flying and swimming faster than the speed of sound. He can fire neuroshock blasts from his eyes and tail, and the stingers on his head carries a powerful poison. Jetray first appears in "Everybody Talks About the Weather" when Ben needed to chase after Alan Albright. He has since become Ben's most common transformation.
Spidermonkey
Spidermonkey is, as the name suggests, a six-limbed monkey-like alien. He has superhuman agility and, like a spider, can spin webs from his tail and stick to walls. He was first seen in "What Are Little Girls Made Of?" to fight his grandmother Verdona Tennyson. When Ben transforms into Spidermonkey, he talks in an excited, childish tone and displays mischievous characteristics with occasional monkey-like screeching.
Swampfire
Swampfire is a Methanosian from the planet Methanos (referring to methane). Swampfire is a plant-like alien with a flame-patterned head. He is a combination of the Florauna and Pyronite forms from the original series.[37] He has super strength, vast regenerative powers, the ability to control plant life through a type of gas, and the ability to shoot fire from his palms. His regenerative ability also allows him to alter his own body, such as tunneling underground in vine form or growing his feet to root himself into the ground.[40] Swampfire is Ben's first transformation when the Omnitrix is recalibrated in "Ben 10 Returns".
