Honestly, I love how dog like and fucked up the second form is, honestly maybe use it as a pre-true form? If that makes any sense. and I feel like the third form would work better as a true form since it screams "time to kill some fags and fuck shit up". The third form also reminds me of Resident Evil 7 type shit, which I dig Just my two cents.

I think the second one works best

The problem is that it is way too complicated for me to draw it. So I would have to simplify its design, but if I do that, I feel like it will lose its effectiveness.
