I had recently gotten my hyakuri kit and decided to customize it into a mini mobile armor warship suit.
Mobile suit mode
There’s no head movement whatsoever though my idea was a space battleship with limbs. Basically a macross / robotech mech.
Flight mode
Booster form
It’s supremely backheavy in this mode but the idea is that this adds the firepower of the twin Gundam as a booster set along with a speed boost.
