While never admitting responsibility for the gas or attempting to right his wrongs, Alva did hold a grudge against Static after he attempted to expose Alva. Despite his best efforts, Alva never captured or figured out Static's secret identity.
Alva was never known for being close to his son. Alva Jr figured out a way to control the effects of the Big Bang gas. When Alva ignored his son, the boy took his discovery and became known as Omnifarious. After Alva found out, his son overdosed on his Bang Baby pellets and turned himself to stone as a consequence. He then used his company resources to find a means to restore his son to normal.
Alva eventually reversed his son's condition through the utilization of other Bang Babies' powers. Despite trying to use Rubberband Man, Talon and Gear as his test subjects, Hotstreak and Static stopped him. When Static found out that this was all to get Alva's son back to normal, Static offered to use his powers to reverse Alva's son's condition. Not to be outdone by a rival, Hotstreak joined Static, and together, they were able to turn Alva's son back to normal. Regaining his son, Alva dropped his vendetta against Static: not long after however, Alva's terminated agent, Dr. Roberts, successfully learned Static's secret identity.
In Milestone Media, Edwin Alva was an adversary of Hardware (Curt Metcalf), not Static, and he was drastically different from his animated appearance. A suave businessman, the eccentric Alva took in child prodigy Metcalf, and developed him as an asset for his company. Metcalf was honored at first, but became more and more wary as he was forced to act out Alva's will. He became Hardware to expose his benefactor. After a violent debut, Hardware calmed down, and was forced to become Alva's enforcer as his employer learned his secret identity. Alva had secretly desired to be a hero too, and developed the Hardware 3.0 armor during the Long Hot Summer. At its unveiling, a large fight broke out involving most of the town's gangs and crime syndicates. Alva managed to save several lives in the armor before being crushed by rubble. After his death, Hardware became CEO of Alva Industries.
