Ruyi Bang and Jingu Bang

Ruyi Bang and Jingu Bang  are Sun Wukong's signature weapons.

Description
Ruyi Bang and Jingu Bang are dark red weapons with gold detailing that has two different forms: a Bō and a pair of gold-chain-linked lever-action shotguns (a form in which they also double as nunchaku).

The staff form appears to be quite strong and durable, as it is capable of sending a full-grown Faunus flying a certain distance, as well as able to withstand a direct shot from Melodic Cudgel. The staff gives off small bursts of energy from the ends when it hits an enemy and can send out a wave of energy when slammed to the ground.

In its 'Nunchaku / Shotgun' form, it can be fired whilst being swung at an enemy, re-chambering with momentum while also being able to deflect Roman's attacks.

Trivia

 * In Journey to the West, the original novel upon which Sun Wukong's character is based, the name of Sun Wukong's staff is Ruyi Jingu Bang/Nyoi Kinko Bō (如意金箍棒, lit. Compliant Gold-Rimmed Staff). The red color of the weapons resembles the more popular variation of how the staff is drawn in adaptations of the original novel, which is a red base with occasional gold-colored ends (nodding to its translated name).
 * The fact that one of its forms is a staff may be a hidden joke: in Chinese the word "gun" refers to a staff. So Sun's weapon may be called a "Gun-gun."
 * It is worth noting however that this weapon is not the Gun-Gun from RTX that Miles Luna and Kerry Shawcross thought up after a fan question, as confirmed by the crew themselves.
 * Judging by its design, it is likely that it can also be used as a sansetsukon (best known as the three-sectional staff).
 * Monty has said that the idea of "shotgun nunchucks" was partly inspired by the famous scene in Terminator 2 where Arnold Schwarzenegger flip-cocks a lever action shotgun with one hand.
 * According to an interview by GVTV with Monty, this set of weapons is one of the earliest ideas conceived by him, along with the name of Sun's Team, the latter being formed ahead of Team JNPR.
