"Green Arrow's found us, and his friends too. Clear out our stash! Nothing gets confiscated!"

- Diaz

Ricardo Diaz, known as the Dragon, is a major antagonist in the sixth season of Arrow. He is the Arrowverse's adaptation of the DC villain Richard Dragon.

He is portrayed by Kirk Acevedo.

Past
Diaz has an extensive criminal record, having been a member of the street gang Scorpions. He was sentenced to life imprisonment without parole but his conviction was overturned due to a technicality.

Stealing components
While stopping a heist on a warehouse of Cadmus Tech, Team Arrow realizes that the team they are encountering are no simple thieves, as they killed two security guards. While they ambush the robbers, their leader tosses a smoke grenade and vanishes. Back at the Arrowcave, Felicity deduces that the thieves were after the components of a military grade 3D printer, which could be used for creating weapons, drones or chemicals. Dinah, who is late for the meeting, informs the team that this fits the modus operandi of a new crime lord in Star City, who goes under the alias "Dragon".

It is soon revealed that John Diggle, who has been suffering from nerve damage since Prometheus' attack on Lian Yu, is buying drugs to keep his hand steady from none other than the Dragon's henchmen. Eventually, one of the dealers informs Diggle that if he wants more of the drug, he must take it up with the boss. Diggle asks for the dealer to make the introductions. Suddenly, the Dragon appears in the flesh, introducing himself to Diggle as Ricardo Diaz. After a brief smalltalk, Diaz orders his dealer to hook up Diggle with the drugs he requires, seemingly having taken a liking to Diggle.

The same night, Diaz' men perform another robbery, this time at PalmerTech. While loading their loot into a truck, they are attacked by Team Arrow but the SUV with the loot drives off. Diggle pursues the car and is able to stop it but suddenly, another car drives up. Diaz exits and fires at Diggle, who is too shocked to act. This allows Diaz to drive off safely, and the car with the stolen goods also escapes.

Diggle uses his knowledge of Diaz' operation to lead the team to Diaz' hideout. When the team attacks the men posted outside, Diaz hears the noise and realizes that the Green Arrow has found them. He orders his men to destroy everything inside the building so that it won't get confisciated. As team Arrow storms into the room, Diaz himself knocks over a vat of a flammable liquid and ignites it, setting fire to all his drugs, including the one Diggle uses against his nerve damage. Diaz then flees from the building.
