They are relatively small Soldier Zombies and they are all roughly the same size as Chopper when he is when using his Brain Point. Gyoro is the zombie that looks like a one-eyed samurai with an ovular head. Nin is the pinkish-red zombie archer with a triangular head. Bao is the yellow zombie that looks like some sort of super hero with a bucket shaped head.
They all seem to be very scared of Gecko Moria, but are still loyal to him, as they notified him when the Straw Hat Pirates came to the island because they thought it would be useful to him. They also respect the Mysterious Four.

They later reported the arrival of the Mysterious Four when they arrived as per Moria's request. After Moria extracted Luffy's shadow, they were then ordered to open the way to Oars by Moria an. They then accompanied their master to view the 900th zombie. When Nami, Usopp, and Chopper fell out of Kumashi, Gyoro, Nin, and Bao ran to catch them but stopped when Oars started moving. The three pirates fled, and the zombies pointed Absalom in their direction to pursue them.
Gyoro, Nin, and Bao looked over Oars after his defeat, worried about their master. However, Moria took their and all other zombies' shadows away to power himself up.
