Z-Type Zaku
Like the high-speed mobile Zaku, also known as the "Octopus Zaku," this is an MS I'd love to see made into a modern kit.
Incidentally, the older guys in my neighborhood called it the "Gorilla Zaku."
During the heyday of MSV (Mobile Suit Variations), everyone apparently thought, "What the heck is this?"
But I think its unusual appearance is part of its charm.

I want to enjoy this sense of strangeness, especially in this day and age (memo). | ふっださん's Gunpla works
