Abilities and Powers
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. What he was about to say was that it was probably a famous person among sailors called Klabautermann which had repaired their ship in Skypiea.
It is assumed that Mekao, like Franky knew that what Usopp saw 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.
