William Tockman (Arrowverse)

"Where are you? Are you home? Are you safe? Somewhere you think is safe? Somewhere without windows for anyone to creep through, underground perhaps? You think no one can get to you? You think no one can touch you in your hide-y hole? But I can!"

- Tockman while hacking Arrow's hideout William Tockman is a minor antagonist in the series "Arrow". He uses henchmen to steal things of value. During heists he tracks his henchmen over security cameras and gives them orders to avoid getting caught. His operations rely on a strict time table.

He is portrayed by Robert Knepper.

History
Tockman is a bank robber and former employee of Kord Industries. He suffers from MacGregor's Syndrome, a terminal illness, but instead of using the stolen money to ameliorate his own condition, spends it to help his sister who has cystic fibrosis.

In the series
He sends two of his henchmen to obtain a device out of a heavily guarded building. He gives his men precise orders which they follow until one of them panics which leads to them getting seen by a security guard whom they shoot. Although they manage to escape, Tockman kills the one responsible for turning his operatíon into murder.

Two of his henchmen rob a bank. Tockman observes them and when he sees the Arrow approaching, warns them to get out immediately.

To avoid his men getting caught he hacks the public transport of Starling City which almost leads to a train colliding with a bus. However, this is foiled by Arrow last minute. He also hacks into Arrow's comunication.

When Arrow finds out Tockman's identity, he arrives at Tockman's van only to find it empty except for a remote signal. When Felicity tries to encrypt the signal, Tockman hacks into her system and fries the entire computer systems inside Arrow's hideout. Arrow plans to give Tockman a target to rob so that he can stop him while he is doing so and leads Tockman into robbing Oliver Queen's vault at Starling Safety Deposit Service.

Taking the bait, Tockman sends two henchman inside and hacks Arrow again, also disabling the gas inside the building to have it explode. After Diggle stops the gas leak and Arrow takes out the men, Tockman appears and shoots at the Canary but misses. Before he can shoot again, Felicity knocks him out by exploding his cellphone.
