This looks more like a Pyrox revamp, but still a great MOC!
I would agree with @LegoDavid, it does look like a revamp, I love the use of the agori limbs to create a more animal leg shape.
The Agori limbs really make this Moc. I’d still say it’s a bit of a Pyrox revamp, though.
I never had the set while it was released but I guess it can go by 2 names, the story could be it is pyroxs husk taken control by the brain slug infused with energized protodurmus, a new super “rakhsi” style
