Alan Chang graduated from Hudson University with a Bachelor in Political Science.
In 2013 Chang ran an operation on crippling Shadowspire with help from Amanda Waller, and they were exposed as not a Special Forces unit, but war profiteers.
In 2016 Chang contacted Lyla Michaels and John Diggle seeking help due to him and other agents involved being pursued by Shadowspire leader Lieutenant Joyner. As he approached Michaels and Diggle, he was shot and kidnapped by Shadowspire operatives. He was later tortured, with his fingernails pulled, multiple lacerations to the knees, a broken arm and contusions before his left eyeball was ripped out. Finally, he was killed, while his eye was used to access A.R.G.U.S. headquarters.
- Peak of human physical condition: As a former soldier and agent of A.R.G.U.S., Chang was in a top physical condition.
- Expert tactician/Leader: Chang led successful operations on A.R.G.U.S.'s behalf.
- Stealth: Chang was able to sneak up up on Lyla Michaels and John Diggle.
- Alan's hobbies, according to A.R.G.U.S. files, were tennis and running.
