Marin is an elderly woman who gets around in a wheelchair that says "Y-1" on the side of the wheel.

She was first seen arriving on Secon Island, via the sea train. When Z activated the Dyna Stone on Secon Island, Kuzan saved Marin, Homey, and Zomino from being hit by a molten rock. The trio thanked him and fled to the Sea Train.
