Duel Chaser

The Duel Chasers (デュエルチェイサーズ Dyueru Cheisāzu) are a group composed of officers belonging to Sector Security in the ''Yu-Gi-Oh! 5D's'' anime. They also exist in the Synchro Dimension, belonging to Security in the Yu-Gi-Oh! ARC-V anime.

Past
The Duel Chasers were created to help control the Commons after they revolted when Chojiro Tokumatsu was arrested ten years ago.

Friendship Cup
Duel Chaser 227 went after Yūgo for trespassing the Tops area of the City. The Duel was then broadcast from a helicopter to various places around the City, including the homes of the Tops, with Melissa Claire commentating. When 227 thought he was about to finish Yūgo off, Roget warned him not to attack, but he didn't listen and allowed Yūgo to win the Duel, which defeated 227 and stopped his D-Wheel. 227 was fired and demoted down to the Commons as a result of this loss, even being arrested by his former colleagues. Shortly thereafter, however, he received an invitation by Roget to enter the Friendship Cup, offering to restore him to his former position if he defeated Yūya Sakaki. However, 227 is defeated and sent to the Underground Labor Facility.

Friendship Cup Finals
When Roget initialized his "King's Gambit" plan, a chip activates on the head of his Security officers and putting them in a trance to follow his orders and assault the Council's room.
