After KOPEKE gets you past the entrance to KO-WAHI, you come up to a gate with two mounds of snow that are looking at you from either side. If you click on the mounds, they reveal themselves to be MATORANS as they shrug off the snow to salute you. This character is the one on the left.

To build him, you need to give MATORO a dark-grey HUNA and the dark-grey legs from the BOXOR pilot.
