Neo Marines

The Neo Marines are a group led by Z in order to annihilate all pirates and the main antagonist group of One Piece Film Z.

Jolly Roger
The Neo Marines Jolly Roger has a skull with slanted eye-sockets and a spiky crown, while the cross-bones is similar to an inverted Marine symbol and a cross or sword with a Yoru-like hilt. The placement of the skull on top of the inverted "wings" give the skull the appearance of elongated tusks.

History
After Z resignated from his poistion of Marine admiral he went and formed his own version of the Marines, Neo Marines, whose target is to destroy all pirates. Z would recruite two Devil Fruit users and a Pacifista army as part of his crew.

Crew Strength
Not much is known of the crew's strength, though seeing that they sail in the New World, it can be assumed that they have a quite a bit of strength. Furthermore, with two Devil Fruit users and a Pacifista army as part of the crew, and the captain being a former Marine admiral, they can be considered a force to be reckoned with. In One Piece Film Z, they managed to steal an item from the Marines called the Dyna Stone, a weapon said to have power to rival the Ancient Weapons, making the group extremely dangerous. Their leader, Z, is said to be "the most powerful opponent yet". If this is taken literally, then it can be assumed that the crew as a whole is a dangerous threat.
