The following couple of sakuga gore scenes in Megazone 23, Part 2 https://www.youtube.com/watch?v=4q2THtU2g_o&t=13m11s

The rest of the video is nowhere near as gory

The Muv Luv series comes to mind. Robots vs unending overwhelming alien hordes who eat people like we eat lobsters. Not my favourite series but very gory.

While the show isn’t in general all that gory, there’s this one scene in the old Bastard!! OAV (the 1990s one) where the MC (as a friend of mine put it) juices a hydra, which has got to have the highest blood-produced-to-creatures-killed ratio of any anime I’ve ever seen.

Another (ts is ass) I have yet to watch hellsing

Elfen Lied.

Made in Abyss is pretty insane.

Fist of the North Star

I’m not much into anime but the only two I can think of are Ninja Scoll and Kite.
