When The Hood arrived at the mental institution to investigate the operation, the accomplice came up behind him and knocked him out. He then witnessed Dr. Webb remove the vigilante's hood and discovered his true identity, Oliver Queen.
With Oliver captured, Webb gave the Accomplice orders to open Oliver's mouth, so he could give him liquid Vertigo. However, Oliver escaped with the help of his partner John Diggle who arrived and struggled with the Accomplice. During the struggle, Diggle dropped his gun, but before the Accomplice could use it, Diggle killed him with a heart defibrillator by shocking him on his head.
- Peak of human physical condition: The man was in top physical condition, able to fight John Diggle and use his strength to keep up with him.
- Expert hand-to-hand combatant: The man possessed skills in unarmed combat, as he went toe-to-toe with John and almost won before getting electrocuted and killed.
- Stealth: Despite his size, the man could move silently and was even able to sneak up on the Hood without getting noticed.
