it's really easy to make that kind a model yourself.
Smooth curves with collapsing fleshy bits are really hard to model, shiny metal with stiff joints are easy to model.

Literally just modify Y/X bot a bunch and put "vrchat standard lite" on it with a really shiny and awesome PBR texture and like 4 materials. It doesn't need to be high poly. 

You could even look like Zapan or Alita if you wanted and just stick the face part of an MMD on some sick ass beefy looking shiny robotic body.
