Sandra Tennyson (post-2010)

Sandra Tennyson is Carl Tennyson's wife and the mother of Ben. While she did have a bad introduction in the Alien Force episode, "Grounded", she’s become a better character in later appearances in the franchise.

Why She's A Much Better Mother Now

 * 1) Sandra has grown from a very strict overprotective mother, to a kinder and more gentle woman who makes sure her son is at his best and is safe, and does not go too overboard when punishing her son.
 * 2) She made more positive appearances in the franchise, like the movie, Ben 10: Destroy All Aliens, and also the sequel series, Ultimate Alien and Omniverse, showing how much she’s grown.
 * 3) She did punish Ben during said movie, but it’s much more understandable since she wasn’t too strict with him, and just made him stay home and do his history report.
 * 4) She’s shown to be a more caring mother, such as during the movie, when she was telling Gwen and Max that Ben ran away, showing worry for her son and wanting to make sure he’s ok. This is also shown more times in Omniverse that she goes out to help out her son, even if it means facing dangerous enemies like Ma Vreedle.
 * 5) She does not have anything negative about herself, as during the movie, turning into an alien was an accident because of Ben’s malfunctioning Omnitrix, and after she was turned back to normal, she calmly tries to recall when she grounded Ben, even if she decides she didn’t because she totally forgot.
 * 6) She lets her family of plumbers fight bad guys, such as in "Hit 'Em Where They Live", when she let Gwen take on a trio of villains to try and protect her.
 * 7) She can be extremely calm, like in above mentioned episode, she was calm after being rescued by Gwen, who used her giant anodite form, and was shown to get used to her super powered family. Also, in "Rules of Engagement", she managed to not freak out when taking to Looma, and had a nice talk with Julie. She then went inside still calm after Ben told her to.
 * 8) She does make healthy food, while Ben doesn’t enjoy it, his partner Rook certainly does.
 * 9) In "Oh, Mother Where Art Thou?", her epic speech about helping her son against Ma Vreedle, which managed to touch her heart and stop her plan.
 * 10) She has a good friendship with Ma Vreedle, and touched her heart when she says she’s her friend, which is also hilarious, considering that Ben and Rook don’t consider the Vreedles their friends.
 * 11) She has some good motherly skills, like teaching Ben and Rook to be polite to the Vreedles when visiting them.
 * 12) She has some funny moments, like when she followed Ben all over town just to give him her healthy food, and when she joined the Vreedles in "washing" their hands.
 * 13) Tara Strong (who also voiced young Ben) and Beth Littleford did a good job voicing her.

Bad Qualities

 * 1) She did not have a good introduction back in Alien Force, along with Carl.
 * 2) She only had a small role in Destroy All Aliens.
