John Diggle, Jr. (Earth-16)

Grant Wilson's uprising
In an alternate timeline visited by the Legends, there was a different version of Connor Hawke, with this one having taken the name John Diggle Jr. Around 2031, Grant Wilson/Deathstroke lead an uprising on Star City, which saw numerous people dead, and those that weren't abandoned it. Around this time, Oliver Queen/Green Arrow engaged Deathstroke in a climactic battle in the streets, which ended with Deathstroke severing Green Arrow's left arm. Oliver soon vanished after this, leaving John to believe he had died. Sometime during the uprising, most of Team Arrow either abandoned the city or were killed, including John's father, which John believes he could have prevented. Blaming himself for his father's death and feeling undeserving of having his name, John started going by the name Connor Hawke. At some point in the next 15 years, Connor took up Oliver's mantle and became the next Green Arrow, trying to hold the city against Deathstroke's army by himself, and soon became the latter's archenemy.

Encountering Rip Hunter's team
"My dad is dead because I couldn't save him. I don't deserve his name. I'm Connor Hawke."

- Connor Hawke to Oliver Queen.

In 2046 Green Arrow saw a group of strangers approaching and perceived them as a threat and approached them. However they mistook him for Oliver and Sara Lance/White Canary of them tried to remind him who she was, while Ray Palmer/The Atom tried to remind him that Rip Hunter recruited them to become legends. However, since Green Arrow had no knowledge of these events he proceeded to engage them anyway. Despite Leonard Snart/Captain Cold and Mick Rory/Heat Wave returning fire Rip ordered everyone back to the ship, and they escaped Green Arrow. Later while several rival gangs erupted into a street war Green Arrow attempted to break up the fight engaging them all at once but got shot by one, though wearing high-density kevlar, and barely escaped. He later came across White Canary and cornered her and upon her asking who he is introduced himself as Green Arrow, but she refused to believe him as Oliver Queen is Green Arrow. However Green Arrow told her that Oliver had been dead for years, after the uprising, but the two were confronted by Deathstroke. Green Arrow and Rip stood ready to fight as White Canary was stunned to see Deathstroke was Grant rather than his father Slade, but they were soon cornered by dozens of Grant's men though the three escaped.

Retreating to safety Green Arrow revealed to Sara that Oliver had tried to oppose Deathstroke by rallying the city but with no success. When overhearing Rip and Sara discuss getting to Smoak Technologies Green Arrow revealed the building had been shutdown for years, but most of Felicity Smoak's projects were relocated to the, now destroyed, Arrowcave. Green Arrow accompanied the two there but the three were stunned to see a still-alive Oliver, still referring to Connor by his real name, but Connor expressed anger towards him for letting everyone believe he was dead, as Oliver expressed disapproval of Connor taking his suit. After being told that Felicity's projects were relocated to a warehouse in Adams and O'Neil Green Arrow accompanied them, briefly expressing annoyance when Rip referred to him by his real name. However they were attacked by Deathstroke's men and Green Arrow was taken captive.

Later Connor was dragged into the same place Oliver had lost his left arm where everyone had gathered to witness Grant execute him. Connor tried to trick Grant into letting him go, issuing a challenge to prove who is the tougher Green Arrow of him and Oliver, but Grant refused and prepared him. However they were interrupted when White Canary was seemingly captured also. However this was a misdirect so Oliver, using a cybernetic left arm and doning his Green Arrow suit once more, could surprise them. As White Canary and Green Arrow (Oliver) fought Deathstroke's men, Deathstroke told Connor he wasn't Green Arrow but an imposter to which Connor replied that same about Grant. While fighting they were aided by the rest of Rip's team including Rip himself, Atom, Captain Cold, Heat Wave, Kendra Saunders/Hawkgirl and Firestorm, while both Green Arrows defeated Deathstroke. As they stand victorious Oliver finally gives Connor his approval as his successor.

After the battle, Connor returns to the Arrowcave with Oliver and Sara. Before Sara leaves, she asks Connor to take care of Oliver. He agrees, and he and Oliver get to work on restoring Star City.
