Well, as you can see is that the reboot of Ben 10 has debuted on Cartoon Network recently (though not in the US) and early fan reception has been fairly divisive (though not as very divisive as Omniverse), but I actually had an idea for a reboot of the series which would've had the lighthearted tone of The Original Series and the serious tone of Alien Force and Ultimate Alien, but less of the wackier tone of Omniverse.

Think Spider-Man: The Animated Series meets Power Rangers Dino Thunder meets Transformers: Prime. I may get backlash for this but one of the influences for this reboot was in fact the Kelvin universe of Star Trek (the opening scene of the 2009 film marked the beginning of the alternate timeline that makes the Kelvin universe) and the Boom! Studios reboot of Mighty Morphin Power Rangers.

Here's how it would start: A team of scavengers called the Ellipsis from the year 1946 travel forward in time in 1976 as they prepare to find Paradox in a Plumber airplane piloted by a twenty-year-old Max Tennyson and his partner Phil as Paradox went in a vortex that led him to go back in time. Soon, one member confronts Phil on the whereabouts of Paradox but Phil tells him that he doesn't know who he was talking to and then the member vaporises him. Not long after, Max uses the Null Void Projector and sends the Ellipsis to the portal. This creates an alternate timeline so that the original timeline doesn't altered. As a result, the Omnitrix's arrival is delayed to five years plus some of the characters' birth years are also changed as in this case Ben and Gwen were born in the year 2000 instead of 1995.

On the characters side. Cousins Ben and Gwen Tennyson are enrolled at Bellwood High and are close to each other (not in a squicky way), while the principal is actually working for the Ellipsis. Who would voice him, you say? I would've pictured either Kelsey Grammer or Ron Perlman. Other students for Bellwood High are characters from the previous four series and these include: Cooper Daniels (a intellectual computer expert and known hacker who has an IQ of 230), Alan Albright (aspiring basketball player), Elena Validus (gymnast), Julie Yamamoto, Manny Armstrong, Pierce Wheels and his cousin Helen, Ester Waterfalls, Kai Greene, Rockford Blonko, Edwin Grandsmith, Ashley "Cash" Murray, James "JT" Trumbo and others.

When compared to his original series counterpart, Ben is laidback, stern and serious, while Gwen is more like her Alien Force/Ultimate Alien self than her original series personality plus there would be annual crossovers with Generator Rex, like Arrow has annual crossover episodes with The Flash.

I'm not putting Jimmy or Will because I don't want the reboot to be a repeat of Ultimate Alien, when Ben became a household name plus the latter is very despised by fans.

Characters

Heroes

Benjamin Andrew Tennyson (voiced by Josh Keaton and Freddie Prinze Jr as an adult from the future) is the main protagonist. An aspiring soccer player, Tennyson dreamed of playing goalkeeper for the Bellwood Bulldogs before discovering a box containing a watch device called the Omnitrix, which chose him and allowed him to transform into aliens via the morphing call "It's hero time, activate...". He is relatively close to his cousin Gwen who shares the same age as him along with their grandfather Max as they used to spend time with him on a stateside journey when they were kids. He is laidback, stern and serious, though he has a sense of humour.

Gwendolyn Sarah Tennyson (voiced by Mae Whitman and Vanessa Marshall as an adult from the future) is the deuteroganist. A black belt in karate, Gwen has a known interest in being a magician as she then realises that her and Ben's grandmother Verdona was previously a sorceress from the Anodyne clan (in this reboot, Verdona is human than an alien), whose original line-up were formed by Merlin in the Medieval ages, when part of the army led by Arthur Pendragon turned against them, becoming the Forever Knights.

Max did not knew he had a daughter until Xylene returned.

Carl and Sandra Tennyson (voiced by Eric McCormack and Lauren Graham) are Ben's parents.

Frank and Natalie "Lily" Tennyson (voiced by Clark Gregg and Jennifer Grey) are Gwen's parents.

Paradox (voiced by Jason Isaacs) is a time-traveller whose origins and name remain a mystery. Prior to the series, he confronted the Ellipsis, which resulted them to go forward in time in the year 1976, which the Ellipsis killed Max Tennyson's Plumber partner Phil.

Gordon and Betty Jean Tennyson (voiced by John Wesley Shipp and Mindy Sterling) are Joel's parents.

Plumbers

Xylene (voiced by Lisa Edelstein): An Uxorite Plumber who was part of the team from the year 1976. After having a brief relationship with Max, which resulted in a daughter named Jade, Xylene left the team in order to help Azmuth and Myaxx to craft the Omnitrix.
