Bullus

The Bullus is one of the primary weapons used in Wyvern Island and is the successor of the Skullus. It is composed of a big metal box, jet thrusters, and a sword.

Machinery
The Machinery is the big metal box and is the biggest part of the Bullus. It contains the Fuel Tank, the Thrusters, and the Sword Compartment. It also has a lot of pistons and different kinds of mechanisms inside that makes the job easier. It has straps that are strapped all over the wearer for more control and stability.

Fuel Tank
The Fuel Tank is located inside the Machinery. It contains all of the fuel that the Thrusters use for flight and three-dimensional maneuver.

Thrusters
The Thrusters are located at the butt of the Machinery. It is the most efficient part of the Bullus, and it is used for flight and three-dimensional maneuver. It uses fuel from the Fuel Tank, and is connected by a wire.

Sword Compartment
The Sword Compartment is placed on top of the Machinery. It holds the primary weapon of the Bullus—a 3.5-feet steel sword. It has piston locks that can be triggered by a button in the Machinery, and is used for preventing the sword from falling down during flight.

Sword
The Sword is the primary weapon of the wearer of the Bullus and is locked inside the Sword Compartment unless the wearer is engaged in combat.

Predecessor
The Bullus' predecessor is the Skullus. Even though it is said that the Bullus is the successor of the Skullus, both of the weapons has nothing in common.
