Mattimeo Tennyson (Dimension 7)

Benjaman Mattimeo "Matti" Tennyson is an anodyte-human hybrid from the planet Vilgaxia (Earth [Dimension 7]) in Ben Ten: Enter the Ultimatrix who wields the Heptitrix.

Appearance
He looks like Ben did at 10, but his hair is bleached white and instead of Ben's old shirt, he wears a yellowed white Oxford with a brown tie. Also, his pants are orange-yellow, as are his eyes.

Personality
He is like 10-year-old Ben, but he likes cranberry juice and beef hot dogs instead of smoothies and chili fries, and plays Quidditch instead of soccer. Also, he is more knowledgeable and likes to fly airtight wood-and-canvas biplanes with rocket boosters around, even in space.

Powers and Abilities
He can turn into all of Ben's aliens up to the end of Ultimate Alien, but cannot Ultimize. He can turn into an additional alien named Dragoon7, and he can turn into a black cat without his Heptitrix.

Weaknesses
He can regenerate, but only 9 times, as opposed to a time lord's 12.

Biography
Vilgax became emperor of Earth when Matti was only 3, and he, his family, and the Plumbers lead a rebellion. He met the Doctor and Clara when he was 6, and got the Heptirix when he was 7. He is now 12, and, unlike Ben, never removed the Heptitrix. He is in his second year at Hogwarts, and Gwen has graduated. He can do 7th-year spells, though.

Family
Matthias Tennyson (his Grandpa Max) Gwendolyn Tennyson Levin (a much older version of Gwen) Ken Tennyson (Dimension 7, the one that got turned into a DNAlien in the prime timeline)

Friends
Nolan (Dimension 7) the Doctor (when he was younger [750 as opposed to 900]) the Plumbers (Dimension 7)

Love Interests
Clara Oswin Oswald (Dimension 7)

Trivia
His Heptitrix looks like the original series Omnitrix, but it is orange-yellow instead of green, wooden instead of dark grey, and off-white instead of white/black.
