No, I'm Ben Tennyson, and I'll do anything to save my family. Omnitrix or not. That's what a hero does.

– Ben to Azmuth.[6]

Ben has been portrayed as preferring to have fun over doing chores such as cleaning, and has openly admitted to neglecting his personal hygiene. However, despite his carefree attitude, Ben has also demonstrated heroic and caring behavior, willing to help and save anyone in need, including his enemies.

While Ben may not be as interested in nerd culture as his cousin Gwen, he has shown some teasing behavior towards it. Ben can be impulsive and reckless, often acting without thinking, which can lead to trouble. He also tends to get bored easily and struggles with math and science.

Ben has had difficulties with a former bully, Kevin Levin, and reportedly developed a fear of public restrooms and avoided the school cafeteria for a period of time. This experience led to a grudge against Kevin, which intensified when Ben discovered that Kevin had his own Omnitrix.

Ben has been known to act without considering the consequences, and his reckless behavior often gets him into trouble. His tendency to make mistakes has been noted by his family members, who sometimes comment on it even if he hasn't done anything wrong.

Ben has admitted to feeling full of himself and being afraid of showing his emotions, often hiding behind various identities. He has expressed that the Omnitrix is the only thing he believes is truly valuable about himself, although he has also shown the ability to focus on the positive.

Despite his flaws, Ben is committed to protecting his family and planet, even when faced with challenges such as losing the Omnitrix. Additionally, Ben is a fan of the fictional series Sumo Slammers.

Because they are under Hex's control, Ben tries to escape as Jetray, but they manage to stop him. Rex and Bobo help Ben fight the two of them, without hurting them, until Agent Six interrupts the fight and says that Providence was going to send a missile to Washington. The three convince Agent Six to join them to fight Hex, so they all fight Hex together and Rex, now confident, removes the Nanites from the Omnitrix causing everyone to return to normal. Providence aborts the missel launch and Ben and Rex defeat Hex.

Versus Alien X

In Alien X-Tinction, Ben is fighting Zombozo as Shock Rock, while a hypnotized Max drives the Rustbucket and Gwen is tied up. After a couple jabs at Zombozo's shopping choices and some fighting, Gwen easily frees herself and she and Max put a stop to Zombozo, much to Ben's annoyance. Back on the road, Max asks the kids where to go next before the summer ends. While Gwen is excited, something is bugging Ben. Ben says he might need a break, which Gwen eventually figures out means that he doesn't want to be a hero with the two of them anymore, flying solo instead. Ben says he wishes he could show off his aliens' true potential, and thinks he can't when people are getting in his way trying to help. Their conversation is cut short when Alien X appears in front of the road, flipping the Rustbucket over by simply letting it hit his outstretched hand.

As Max and the kids recover, Alien X moves towards them. Ben tries to fight Alien X, but the villain gets the upper hand. The Tennysons flee to an abandoned factory and catch their breath. Ben complains that he was going to defeat Alien X if Max and Gwen had not gotten in his way. Gwen and Ben start to argue over it until Max breaks them up, saying they need to formulate a plan. All of a sudden, a green portal flashes and out comes Maximilian. Ben impatiently transforms into Diamondhead, but Maximilian explains to him that they are all part of a larger Omniverse that Alien X is storming through, wanting nothing less than the collection of every Omnitrix from every alternate Ben Tennyson. Diamondhead doesn't want to be used as bait, and Maximilian gets angry that he doesn't understand the importance of his safety, to the point of clashing with him over it. Alien X interrupts them and Diamondhead denies running away. Alien X quickly breaks down the door and uppercuts Diamondhead to the second floor, where he times out. Maximilian gives Ben an opportunity to run away, and so Alien X locks him.

Alien X takes the Omnitrix

Ben runs away in terror and Alien X quickly catches up to him. Ben turns into Rath and fights Alien X outside in a forest; however Alien X's teleportation, telekinesis, and other skills prove to be too powerful and Rath loses hard. On the roof of the factory, Ben times out and Alien X grabs him by his Omnitrix. Just as he prepares to take it, Maximilian interrupts and shoots Alien X with a blast from his arm cannon, the feedback accidentally making the Omnitrix detach itself from Ben's arm while still in Alien X's hand. Alien X places Ben's Omnitrix in the center of his chest and leaves through a portal. Ben is devastated. Maximilian surmises this dimension's Omnitrix has a failsafe release and tells the Ben to be grateful he still lives. Gwen tries to come up with a plan to get it back, such as finding a dimension where Ben hasn't yet found the Omnitrix. Max tells them he's stuck in their dimension, as there doesn't exist an omniversal roadside service that drops in out of thin air.

Getting to know Alien Force Ben

Suddenly, another portal opens and out steps what Maximus identifies as a Crystalsapien. It introduces itself as Chromastone, before reverting into a teenage version of Ben from a different dimension. He, like Maximilian, has been tracking Alien X through the dimensions and also frustrates over getting to him too late. However, unlike Maximilian, he has the assistance of an intergalactic law enforcement agency known as the Plumbers (something Max is surprisingly aware of and tries to steer the conversation away from); and that with his portal generator, he has no transportation problems. Maximilian offers to join this Ben (aka Alien Force Ben), but he refuses. Gwen suggest that since Alien Force Ben still has an Omnitrix, they can use him to lure Alien X back to this dimension. Maximus believes that the plan will never work because of Ben being a stubborn brat, which offends Max. Ben breaks up all the arguments when he agrees with Gwen's plan, believing two Bens can stand a chance against Alien X.

While Maximilian searches for another Omnitrix using the portal generator, the others plan to set a trap for Alien X. Ben picks the location: his favorite amusement park Adrenaland. Not only does he know the area well, but it is closed for the season and there are no people to get caught up in the fighting. The Tennysons and Chromastone build their trap using attractions throughout the park. When Alien X eventually arrives in search of Alien Force Ben's Omnitrix, he transforms into a Necrofriggian named Big Chill and orders the other Tennysons to activate the trap. However, the trap fails, Big Chill is defeated, and Alien X decides to rethink his prior mercy and take Ben's life. Before he does, Maximilian returns with another Ben from another dimension. This one looks undisguisable to the other teenage Ben, but has a different watch. Ordering Maximilian to take Ben to safety, he (Ultimate Alien Ben) turns into an Amperi named Ampfibian, teaming up with Alien Force Ben as Chromastone to take on Alien X. As Gwen and Ben watch, she makes him realize they need to expand their family even more. Ben takes the portal generator from Maximilian and pulls him through a portal to find more Bens; Gwen understands because the only person who Ben will listen to is himself.

Ben retrieves the Omnitrix

The reinforcements are two new alternate Ben 10s (Original Series Ben and Omniverse Ben), as well as a Gwen 10. They all transform into their own aliens and try to take shots at Alien X, but he manages them all. As Alien Force Ben admits that they are not winning, Alien X lifts up a giant rock and throws it at them, forcing them inside a cave and blocking the entrance. They all sulk over not being able to put a dent in Alien X. Ben realizes that they all have the same problem: they're too hard-headed and try to take Alien X on one at a time. In order to win, they have to synchronize their powers and work together, as a team and as a family. With a newfound attitude, Team Tennyson busts out of the cave entrance and makes their stand against Alien X. They fight against him, protecting their teammates when in danger and pressuring Alien X to focus on defending against attacks from all directions. Eventually Gwen 10, as Ripjaws, pulls Ben's Omnitrix out of Alien X's chest, and Ben finally takes it back. He turns into Heatblast and teams up with Original Series Ben, also as Heatblast. The team regroups and attacks Alien X, pulling off as many Omnitrixes as they can before he pushes them away. Ben, as Four Arms, beats Alien X's punch with his "Quadruple-Decker Knuckle Sandwich", finally defeating Alien X.

Team Tennyson united

Alien X then detransforms, revealing he was also an alternate version of Ben this entire time. Maximilian then tells him that he could always start anew, if he had people willing to accept him as his new family, offering himself. Ben is appalled, but Maximilian explains that while this Ben needs to pay for his crimes, he isn't beyond help, and that the people who love Ben would offer him a second chance, were he in this Ben's shoes. Evil Ben says he'd rather go back to the Null Void, but Maximilian promises him that after his sentence, they'll both be spending some quality "grandfather/evil-grandson time". Maximilian opens an exit portal and thanks Team Tennyson for reminding him that everyone needs a family. All the alternate Bens and Gwen celebrate saving the omniverse and say goodbye as they exit. After everyone leaves, Max tells Gwen that they should probably give Ben some space, but Ben surprisingly hugs them and tells them to never leave him again, saying he'd rather be with them than ever riding solo. Max informs them that that means Team Tennyson is back on the road!
