All history and corresponding appearances of Arm-Fall-Off-Boy were erased from continuity following the events of the limited series Zero Hour: Crisis in Time (1994). They were brought back into the main continuity in The Lightning Saga (2007), up until DC Rebirth (2016). Even though versions of the character may have since appeared, this information does not apply to those versions.
