Mobley was born on January 2, 1984. He lives in Brooklyn. He is a fan of an obscure DJ from whom he took his hacker name. He even created an Angelfire page in DJ Mobley's honor.
By Thanksgiving of 2014, he is working with Trenton under Darlene, meeting in a Ron's Coffee shop. In December, he secures the abandoned Fun Society Arcade as their base, while also recruiting experienced hacker, Leslie Romero. He meets Elliot some time in between these events. He works at Bank of E and often visits Romero at his home.
In February, Mobley is involved in the attack on E Corp's servers. He is seen at the arcade when Elliot is led visits the morning after the attack. (“eps1.0_hellofriend.mov”) After Terry Colby is arrested, Mobly tries to shake Elliot's hand at the arcade, but is quickly embarrassed. (“eps1.1_ones-and-zer0es.mpeg”)
On March 29th, Mobley is in the arcade when the group decides to alter the Steel Mountain plan and infiltrate ASAP. He has already downloaded the floor plans of the facilities and is confident he can map out their route in the car. He helps steal a minivan with Romero, who expresses a lack of trust in Elliot while Mobley trusts in how far they've come. The group makes a stop at a motel to battle Elliot's detox.

Mobley helps Elliot plant the Raspberry Pi, as he crucially distracts the supervisor standing in Elliot's way with a forged text. (“eps1.4_3xpl0its.wmv”) Later on May 8th, he is with fsociety at the arcade as they alter the plan to hit all five Steel Mountain facilities. Mobley wants to reroute the thermostat company's traffic to erase all signs of their activity. (“eps1.7_wh1ter0se.m4v”)
After the 5/9 hack, Mobley helps burn the equipment and then DJs the End of the World Party at the arcade. (“eps1.9_zer0-day.avi”)
Mobley is the close confidant of Darlene when she takes charge of fsociety. He is with her when they take over the smart house of Susan Jacobs as their new base. He says her speech rallying their militants sounds like George W. Bush. Mobley expresses frustration that the group has been reduced to vandalism compared to what they accomplished. She urges him to be dedicated and help their revolution go all the way. When he asks if she's seen Elliot, she deflects. (“eps2.0_unm4sk-pt1.tc”)
Mobley visits Romero's house, speaks briefly to his mother, and finds him dead on the floor, a pool of blood around his head. When he tells Darlene, she reminds him that she and Elliot warned them that his drug business made him a liabiliy before chastising him for being seen by Romero's mother. At Trenton's house, he voices concern about the danger to Darlene, wondering if it was Dark Army. When Darlene dismisses his fears and threat to hide with a buddy in Arizona, Mobley confides in Trenton that he doesn't trust either of the Aldersons. He disagrees with Darlene's agenda of using stunts with Scott Knowles in order to kill public confidence in E Corp and thinks Elliot is "crazy" for pulling a gun on Romero. (“eps2.1_k3rnel-pan1c.ksd”)
He attempts to teach Angela how to hack when she is brought into the group to hack the FBI. He expresses his doubts to Darlene that she can learn all that she needs in 24 hours. (“eps2.4_m4ster_s1ave.aes”) On July 4, he and fsociety are discovered by Susan Jacobs when she returns home. After she is tied up and subsequently killed by Darlene(by a tazer, Darlene intended to scare her off; Susan has a heart condition), he expresses his plan to flee to Trenton. He pays a pizza guy to check out his apartment and then asks for the pizza, although the FBI do eventually take him in for questioning.
Agent Dominique DiPierro discovered a flyer for the End of the World Party at the Romero residence. She found the Angelfire page and tracked it back to Mobley. He succinctly asks for a lawyer. Upon being released, he texts Trenton to meet him before discarding his phone. (“eps2.6_succ3ss0r.p12”) As of August 7, neither Trenton nor he has been in contact with Darlene.
Some time later, he is seen living in Arizona with Trenton. They live with his friend and work at an electronics store under the names Frederick and Tanya. On their break, Trenton wants to talk about something she discovered, pertaining to life back home and undoing "this whole thing and put everything back the way it was", but Mobley wants none of it. Leon(Elliot's prison-mate) approaches them and asks the time. (“eps2.9_pyth0n_pt2.p7z”)
