Binz is a rather tall and lanky man, with large lips and broad shoulders that appear disproportional to his long arms. He dresses in a flamboyantly colorful outfit with a black and yellow over-suit, and a hot pink body suit underneath which also covers his head. He wears a green sash around his waist and carries a sword and a large shuriken on his back, tied on by a light pink cloth. His appearance strongly resembles that of a ninja.
Binz shares Z's hatred toward pirates. Having been trained under the former admiral, he also has a great deal of respect towards him, as he calls him "Z-sensei". Binz seems to be a serious man of few words, though he is prone to dancing oddly and making bizarre facial expressions in battle. He also cared deeply for Z as he, along with Ain, tearfully mourned his death.
Being an officer of the Neo Marines, his fighting power should be at least sufficient to survive in the New World. He was able to keep up with Sanji twice in a row before losing to him in the second fight.
When he was a Marine soldier he fought with Z and Ain against a powerful pirate that cut off Z's arm. He and Ain were the only soldiers other than Z to survive.
After the pirate in question becoming a Shichibukai caused Z's insubordination, Binz, out of loyalty, resigned his position as a Marine Officer, alongside Z and Ain, and all three would become the founding members of the Neo Marines.
Binz was first seen attacking Firs Island in order to retrieve the Dyna Stone. He attacked the Marines stationed there, and helped his master, Z retrieve the stone. When Borsalino arrived, he rushed his men onto the ship. When the island exploded, Binz was shown worrying about Z's fate.
He was next seen at Secon Island getting briefed by Z along with Ain as they detonated the Dyna Stones that would destroy the island, fulfilling the second phase of Z's plan. Luffy, Zoro, Sanji and Usopp showed up demanding Ain change back Nami, Chopper, Robin and Brook to their respective ages. Z orders his two subordinates to attack with Binz taking on Sanji. Sanji fares much better in the fight, managing to even kick Binz in the face before Binz flees via a smoke bomb to escape the island's explosion. He regrouped with Z, Ain and the Neo Marines as the they watched Secon Island's destruction.
After which the Neo Marines head to Piriodo to execute the final phase of Z's plan. However, the Straw Hats invaded and fought their forces. He met up with Sanji in a watered area and the two fought for a final time. Binz used his power to fire plants and water sprouts at Sanji. However, the cook dodged his attacks with ease and managed to defeat him. Binz recovered in time to join Ain just as they found Z finishing his battle with Luffy. Z, now having a change of heart, apologized to the two for all the work he put them through, but their reunion was cut short by the arrival of Borsalino and his Marine squad. Binz watched helplessly as Z went to fight them in order to allow the Straw Hats and the Neo Marines to escape, blocked from pursuing by a ice wall made by Kuzan.
He was last seen at the makeshift grave of Z, mourning him alongside Ain and being comforted by Kuzan.
