Ben 10

===Sex & Nudity===
 Some teen flirting and kissing. In some episodes, the characters wears theirs swimsuits, revealing skin.
===Violence & Gore===
Sci-fi action violence including aliens and, often, humans. Sometimes gets pretty explicit for a Y7 show.
Little to no blood.
===Profanity===
None
===Alcohol/Drugs/Smoking===
None
===Frightening/Intense Scenes===
Some of the fight scenes get pretty nasty. If such level of violence was performed on humans, it would easily be a PG-13.
The series has a much darker tone than the previous one, and lot of characters die, which may disturb young watchers.
Some of the aliens look terrifying.
