Ben Tennyson

Benjamin Kirby Tennyson, also known as Ben Tennyson, is the main protagonist of the interesting and enjoyable cartoon series called Ben 10, along with its sequel series, Alien Force, Ultimate Alien, and Omniverse. He is a teen who found a device that allows it's user to turn into various different alien forms called the Omnitrix at 10.

Why He Rocks

 * 1) His powers are unique.
 * 2) He is mature when he needs to be as shown in these episodes: the original series’ "Kevin 11" where he doesn't let Kevin hurt innocent lives, or in Ultimate Alien’s "Ultimate Enemy: Part 2" where he gains so many power but chooses to save humanity instead of destroying and killing every villian in existence.
 * 3) He is a great leader in the first 2 seasons of Alien Force.
 * 4) He believes that having an equipment is not the thing of what makes a great hero.
 * 5) He is one of the most famous cartoon characters in history.
 * 6) Tara Strong and Yuri Lowenthal did an amazing job voicing him as a kid and teenager, respectively.
 * 7) He can turn into various different species.
 * 8) He never lets down any of his allies, he trusts people, this can be seen in the original series’ episode "Kevin 11" where he trusts Kevin about him being on his side.
 * 9) He deeply cares for his family (his parents Carl and Sandra, his grandpa Max, his cousin Gwen, etc.), and his friends (Kevin, Rook, his current girlfriend Kai, etc.), and will do anything for them.
 * 10) He and Rook have an awesome and believable friendship, and they always help each other out.
 * 11) He did have a good relationship with Julie, having cute moments, giving both characters more growth, and they had a kiss in "The Ultimate Enemy: Part 2" (until it got ruined, see below).
 * 12) His current relationship with Kai is decent, with Kai being a character introduced in the original series, and they do have some cute moments.

The Only Bad Qualities

 * 1) He can be cocky and immature at times, especially in Season 3 of Alien Force.
 * 2) The relationship he had with Julie was ruined in Omniverse because of the writers wanting to push her aside after Dwayne McDuffie‘s death, and the reason they broke up was petty: because of Ben's insults toward a video game. At least his current relationship with Kai is decent, as mentioned above.
 * 3) His 2016 reboot self was flanderized a bit, but managed to get slightly better overtime and massively improved in Season 5.
