Max Tennyson (Ben 10)

Magister Maxwell "Max" Tennyson or Grandpa Max as his grandchildren call him, is the paternal grandfather of Ben and Gwen. He is a fairly overweight man in his late 50's to early 60's, with a keen sense for adventure and a strange taste in food.

Why He Rocks

 * 1) Unlike most other elderly men in cartoons and anime, he is shown to be a strong, fun-loving guy with a sense of adventure.
 * 2) His design in the first four Ben 10 shows is very iconic. His design in Omniverse is also a fun reference to Shazam.
 * 3) Although he is a fun-loving guy, he has been seen to get serious, like when he scolded Ben for sneaking into a private arcade at a hotel in Kevin 11, and when he seemingly sacrificed himself to protect Ben and the others from the Highbreed in Maxed Out.
 * 4) Despite him being elderly and overweight, he is shown to be surprisingly agile, having him take out many foes and enemies throughout the series.
 * 5) While he may not seem like it, he is one of the strongest Plumbers in the show.
 * 6) Speaking of Plumbers, in the episode Truth, the scene where he was revealed to be a part of a special force team called the Plumbers was mind-blowing to many kids and fans, as most just assumed that he was a boring, old grandpa
 * 7) All of his voice actors do a great job at voicing him.
 * 8) He is one of the few characters from the original Ben 10 series to not be flanderized in the reboot, as he still retains his fun-loving, adventurous personality.
 * 9) He is extremely intelligent, even knowing about Vilgax watching Ben.
 * 10) In Alien Force, he even trained the Plumbers Helpers so they could get strong.

Bad Qualities

 * 1) His old age could be a weakness, such as when his nervous system got destroyed by Aggregor.
 * 2) While he is still a likable character, his design in the Ben 10 reboot is awful.
