Helmeppo

Chief Petty Officer Helmeppo (ヘルメッポ, Herumeppo?) is Morgan's bratty son. He is now a Marine Chief Petty Officer under the command of Garp along with Coby. Helmeppo was a coward who hid behind his father's wealth and power. Helmeppo loved his father and thought his father loved him back. However, Morgan only thinks of Helmeppo as a worthless son. After Morgan is arrested, Helmeppo lost access to all the luxurious life that he once held, and so he reluctantly becomes a Marine. Since then, Helmeppo goes under the tutelage of Garp with Coby. Thanks to Garp, Helmeppo now has very decent fighting abilities as he wields dual kukri as his weapon of choice. He is voiced by Kōichi Nagano in the Japanese version. In the English dubs, he is voiced by Sean Schemmel for 4Kids and by Mike McFarland for Funimation.
