His videos can be a bit violent to little kids. Blood and violence is common in his new videos. But it's mostly TV-14 at worst.
People die/injure themselves or by someone in various ways, whether it's getting chopped like sushi, beaten up to death, ( slapped and squished ), crushed, roll down... no matter which one, all will be bloodly as hell.
In The videos Pain, I Almost died (3 times), my brother almost died (18 times) do have a lot of violence and blood.
Violence isn't frequent, ( sorta ), but in episodes that revolve around the subject of pain, there will be a lot of horrible acts.
Bryson beats people up and/or kills them for little reason a lot of times, but it is cartoonish and played for laughs most of the time.
In "My Bully Brother", as a joke, Brayden pulls out his heart with lots of blood surrounding it. But this is brief and only lasts a couple of seconds.
The old-ish videos have these random segments where Bryson just gets hurt with lots of blood and bones. Everyone would find these scenes funny or gross.
Bryson's new videos dont have any violence anymore. I guess too many people got sick of it.
