Lots of fighting and some bloodless, non-graphic onscreen deaths.
At different times, two horses are killed by wolves. Some blood.
Despite this being labeled as a kids show, it gets more and more dark and violent as it goes. By season 6, you might as well say it's not a kids show.
Keep in mind that most the ratings made on this show were around the seasons 1-3 time, but the show escalated from there. So the ratings for The Dragon Prince is PG, Mystery of Aaravos is 12 and the upcoming sequel "The Dragon King" will be adult so 18 ig.
