Abilities and Powers
He is an old mechanic and shipwright who shows great pride in his work.
In the G-8 Arc, Usopp explains to him what he saw next to the Going Merry back in Skypiea. Mekao was about to explain to him what he might have seen, but Drake pulled him away before he could do so. He later helps the Straw Hat Pirates escape the base.
It is assumed that Mekao, like Franky, knew that what Usopp saw repairing the Going Merry was a Klabautermann. However he could not have said that it was a Klabautermann because at that time Oda had not yet revealed it and would only reveal it much later during the Water 7 Arc.
