Kenny Tennyson (Ult. Timeline)

Ken Tennyson is the son of Ben 10,000, primarily the one known as "Ultimate Ben". His mother in this timeline is Julie Tennyson. He hails from a timeline where his father had kept the Ultimatrix. Similar to his Prime counterpart, he too wields an Omnitrix replica. He is a Human from the planet Earth of an alternate timeline.

Appearance
The primary difference between this Ken and his Prime counterpart is his physical appearance. This is due to his mother being Julie Tennyson in this timeline. Kenny bears a striking resemblance to his father when he was his age. Caucasian complexion, green eyes, etc. The primary difference though is his black hair, inherited from his mother.

His sense of clothing is similar to his father's in his youth. Wearing a black shirt with a white stripe, blue jeans, and a generic looking green jacket. This is due to him trying to emulate his father. He wears the Omnitrix replica on his left wrist.

Underneath his left eye is a faded scar, received when trying to assist his father during the third Vilgaxian invasion.

Personality
Kenny is very much like his father was when he was his age. A bit cocky, wanting to get involved in the action, but at the same time, knows when to do the right thing. All too similar to his counterpart. The primary difference is that Ken is aware of the dangerous aspects of the "hero business" and acts accordingly. He rarely panics, trying to hide the fact that he's scared of the consequences.

Although he does look up to his father, he does seek out to be a carbon based copy of him. Wishing to be his own man, even if by just the little details. He used the intellect of Grey Matter to unlock the master control to avoid the hindrance of his father's youth. He feels a tad overwhelmed by his father's reputation, being both Earth's greatest hero and a former president. He's actually willing to take a back seat and let his father handle things, but is aware that one day that he'll have to step up to the plate.

Similar to his father, his antagonizing of his sister, Gwen, is almost a mirror of how Ben and Gwendolyn behaved. Annoying her, occasionally belittling her for not wanting to be involved in the "family business". He is best friends with Devlin Levin, acting like brothers in a sense. He is also fond and protective of his pet Stone Creature, Quartz.

Unlike most, Ken is actually fond of the alien form, Fasttrack. Upon receiving the Omnitrix replica, he traded out XLR8 for Fasttrack, stating that XLR8 was "his father's go-to" and wanted to make Fasttrack his own.

Powers and Abilities
Ken wields an Omnitrix replica, gifted to him by Azmuth on his 10th birthday. Same as his father, he's able to transform into a multitude of alien forms, equipped with their respective abilities. Starting out, he is only enabled one playlist of ten aliens currently (Fasttrack, Ditto, Stinkfly, Snakepit, Upchuck, Swampfire, Buzzshock, Shell-head, Toe-pick, and Grey Matter).

Being often exposed to his father's career, Ken has extensive knowledge concerning his alien form and their abilities. He is capable of adapting between alien forms, as well as combining their powers in tandem. This is well evident when he is fighting alongside his father and cousin Devlin via Mutant form.

Thanks to his hacking via Grey Matter's intellect, his Omnitrix no longer has a depleting power supply. Enabling him to keep on fighting in alien form, and without fear of timing out mid-battle.

Not wanting to be dependent on the Omnitrix, he is taught self-defense by his Aunt Gwendolyn, yet is stuck with learning the basics. He began learning how to use blasters and such by the tutelage of his Great-Grandpa Max (then under Kevin Levin after Max's passing).

Weaknesses
Although his Omnitrix is limited by power supply rather than a time limit, it has to revert him back at some point. This frequently seems to be the case whenever his alien forms receive too much damage, reverting to avoid further injury to the form. Even when Ken has seemingly unlocked the master control, he still suffers having to turn back to normal sooner or later.

It's later revealed that upon request of his father, Azmuth had programmed a voice command that would force the Omnitrix to revert him back upon force. This was made as a contingency if the situation called for it.

Whenever caught having to fight in his human form, the evident being that human form is without empowerment. He is more vulnerable to injury outside of alien form, and only do so much with the outside training he has been receiving in terms of combat.

It turns out another weakness being that his Omnitrix replica is not as powerful as his father's Ultimatrix nor even the original prototype. This is due to Azmuth not constructing it with the full capabilities as the original, not believing that Ken would be in need of them. Meaning that Ken's Omnitrix cannot scan DNA, repair DNA, etc.

Biography
Ken Maxwell Tennyson was born of Ben 10,000 and Julie Tennyson (nee' Yamato). Growing up, he was well exposed to his father's heroics. From the career of Ben 10,000 to Ultimate Ben to even President of the United States. Ken wanting to join his father, was ecstatic when "Uncle Azmuth" gave him an Omnitrix on his 10th birthday. Though getting his kicks in, Ken was occasionally overwhelmed by the legacy of his father. Often fearing for the future, but choosing to have fun for the present.

Apparently Ken was present when the third Vilgaxian invasion occurred during his father's presidency. Assisting in on the action, he apparently was injured, resulting in a scar underneath his left eye.

Ken was also there when it was revealed that Spanner, the new time-traveling hero, turned out to be his sister, Gwen. He was shocked, and very protective of her from then on. He was begrudging, by was willing to allow her to carry on with her own heroics.

Family
Ben Tennyson (father) - Fathered by the hero of heroes, Ken has quite the legacy to live up to. Though the two do having a loving relationship, there will be the occasional hiccup caused by their heroics and such. Ben is proud that Ken does strive to be his own man, and try to remind him that he doesn't even have to bother with the heroics.

Julie Tennyson (mother) - Former Olympic Tennis athlete, Julie is a very loving mother for her children. Even went as far as to become a stay at home mom. At first she wasn't welcoming of the heroics and Omnitrix when Ken was the concern, but eventually allowed it. Following such, she pretty much became the rock for Ken to lean on when the heroics became too much for it.

Gwen Tennyson (sister) - Akin with those before them, Ken and Gwen seem to bicker a lot. A sibling rivalry that held no bounds. Initially, Ken use of insults for her were related to lack of desire to be "in on the family business". Though this ceased after he discovered her secret identity as the Spanner of their timeline. Even though they bicker, the two do love each other and will go to great lengths to protect the other.

Friends
Devlin Levin (friend/cousin) - Son of Kevin and Gwendolyn Levin, and the best friend that Ken could ask for. The two play often whenever they aren't consumed by the antics of their parents' careers, and even fight alongside each when they are in battle with evil. Often by mistake, those outside the family have assumed them to be brothers, rather than cousins, because of their closeness.

Other
Quartz (pet) - A Stone Creature gifted to him by Aunt Gwendolyn on his 10th birthday. Unlike most of it's kind, Quartz is rather puppy-like than humanoid, right down to the personality. Ken is really fond of Quartz, and is really protective of him. This was evident when Quartz was supposedly destroyed by an enemy, sending Ken into a flying rage. Though Quartz can regenerate, Ken would rather not chance it.

Trivia

 * His middle name, Maxwell, is clearly named after Grandpa Max.
 * Contrast with his counterpart, Ken is rather content with the limiting behavior the adults project onto him. This seems to be due to him not wanting to tackle the full legacy of his father.
 * With Julie Tennyson (nee' Yamato) as his mother, this would mean that the Ken of this timeline is of Asian decent.
