He uses the Prototype Omnitrix to become a hero while traveling across the USA.

Before discovering and '''reinventing''' her dormant magic powers, she helped Ben using her innate intelligence; she is also a talented martial artist who has received black belts in karate and taekwondo. Gwen is a model student, and in ''Omniverse'', she is shown leaving for an Ivy League College.

Gwen is able to manipulate mystical energy named "mana" to create energy blasts, shields, and other constructs. She later learns that her powers are not magic in origin, but rather alien, and her paternal grandmother, Verdona, is a powerful Anodite alien who can manipulate mana, the essence of magic and life.<ref>{{cite web|last=Weir|first=Melanie|title=Here's Why {{'}}''Ben 10 Alien Force''{{'}} Was An Underrated Show|url=https://www.thethings.com/heres-why-ben-10-alien-force-was-an-underrated-show|publisher=The Things|access-date=June 4, 2020|date=June 4, 2020}}</ref> Gwen cannot take on a fully Anodite form at will unless she masters it.

Max was once a candidate for the Apollo 11 mission and one of the leaders, or "Magisters", of the Plumber organization, but Ben and Gwen did not know of this at first, believing him to have been a literal plumber.

However, Kevin was also infused with the DNA of the aliens Ben had access to at the time and became a chimeric hybrid of the alien forms, which rendered him psychotic and unstable. Kevin managed to return to his original form after being trapped in the Null Void. In ''Omniverse'', it is revealed that Kevin is actually a human and derived his powers from a genetic mutation.

In the reboot, Kevin is a human who wields the Antitrix, a version of the Omnitrix that allows him to transform into modified versions of Ben's aliens.<ref>{{Cite web |last=Haring |first=Bruce |date=January 12, 2019 |title='Ben 10' Heading To 4th Season, As Cartoon Network Greenlights New Episodes |url=https://deadline.com/2019/01/ben-10-will-get-4-seasons-that-is-as-cartoon-network-greenlights-new-episodes-1202534126/ |access-date=May 7, 2026 |website=Deadline |language=en-US}}</ref>
