Although there is certainly plenty of violence against men too, a lot of the violence against women in this series felt very sexually objectifying. A lot of nude or partially nude women being violently brutalized in a sexually objectifying way.
Here are all the time stamps for dead or injured animals:
The Secret War: 1:20-1:23, 9:07-9:20, and 11:18-11:26.
Alternate Histories: 2:13-2:24
Ice Age: 2:14-2:20 and 8:18-8:50
Fish Night: 5:45-5:47
The Dump: Start to 0:50, 6:50-7:18
Suits: 3:09 to 3:30
Sonnie's Edge: monster fight scene 7:05 to 10:20
Shape Shifters: werewolf fight scene at the end
Implied cat death at the end of episode 4, “SUCKER OF SOULS”.
(spoilers ahead) It is not shown, but the last thing to be heard is a cat growling at a horde of vampires, then the episode ends.
Season 1 “Sonnies Edge” - ***VISUAL AND AUDITORY*** neon snake imagery shown before fight and snake tattoos on Sonnie. Serpentine hissing can be heard from the monster
"Good Hunting" involves one of the main characters being forcefully turned into an android/machine against her will. It shows a couple graphic seconds of the process.
This is the WORSED show to watch if you are sensitive to any pain in shows or movies. There are many scenes that are very violent and have no warning. SPOILER! A girl gets stabbed through the brain then gets her head stomped on multiple times in just the first episode, I was too even too scared to go to the next scene/episode. Although its animation, it is very detailed.
Warning for season 3:
Ep 2 "bad traveling" around 1 minutes and 20 seconds the man * when the crab eats a human
Ep 6 "swarm" Around 11 minutes the man v*
The rest of the season is safe but there are several blood spits and times when you think it's going to happen but nothing else happens.
A lesbian woman is brutalized and a bisexual character is killed in "Sonnie's Edge."
The death of a lesbian woman is implied at the end of "Soul Sucker."
Episode 1, right after the sexually suggestive scene, the main character of the episode gets "killed" in a very graphic way.
The scene in question is pretty much the ending from 13:30 to 15:18. It's an important scene but it's violent so it's best to be aware of it.
