AMX-109 Capule
An amphibious mobile suit developed by Haman Karn's Neo Zeon. Its spherical body, which concealed missile launchers and beam cannons, enabled it to cruise in water at high speed, and it packed powerful claws on its extending arms.

Despite not seeing much action during its initial deployment (as Axis's incursion on Earth was repealed by the Gundam Team), remaining Capules were fielded by Zeon remnants as far as UC 0096, and some of those units somehow survived through thousands and thousands of years untouched, eventually being unearthed by future generations to fight against the Moonrace - those millennia-old machines being nicknamed "Kapool".
