Prometheus

Prometheus's weapons

Axe

Adrian carried at least one axe, which he used to attack Tobias Church.

Chokuto

Adrian carried a chokuto on his back for close quarters combat.

Pistol

Adrian used a pistol when taking William Clayton hostage and later killing himself.

Recurve Bow

Although rarely used, Adrian carried a recurve bow, which he used to fire his arrows and for close combat.

Shurikens

Adrian carried Shurikens strapped to his abdomen, usually no more than six at a time. These appeared to be his preferred method of killing his victims.

Throwing Knives

Adrian carried several smaller and easily concealable throwing knives.

Prometheus's equipment

Prometheus Suit

Adrian wore a protective suit as Prometheus to hide his identity from his victims in his quest for vengeance against Oliver Queen.

Quiver

Adrian carried a black arrow container, to carry his arrows with him.

Voice Filter

Adrian apparently used a voice filter in his mask to conceal his true identity and making him sound almost unrecognizable as Prometheus. For some reason, he made several alterations to his disguised voice. This is possibly what he used to mimic Lyla Michaels' voice to trick John Diggle.

Grappling Hook

Adrian used a grappling hook to descend down a building and into a window during a confrontation with Oliver.
