Compared to his crewmates Macro is considered the brain of the crew. He has a distinct laugh being Mohahahaha Even though Macro was part of the crew of Fisher Tiger the fishman who fought against slavery Macro as well as his two companions do not have any qualms selling other fishmen and merfolk to slavery
However he wasnt always so cruel While he was with the Sun Pirates he had a soft side to him as shown when he got attached to the former Koala and he greatly missed her
