Advance editing tips (War Cry)

Good morning! First of all, if I have chosen the wrong forum, sorry!

I’ve been looking help for my current project, which is a War Cry, but not any ordinary, let’s say it’s 2 second part from here
To be honest, I have managed to replicate better or worse voice covers of Smaug, Venom, Gandalf, Dreadnought, and so on, but this piece, I’m stuck. Using low pass filter makes this kind of muffle effect, pitching makes almost no difference, well filter curve do some work, but overall I’m way above success. The war cry itself vibrating a bit, and I have never heard better before. Any ideas?
