Henry King Sr. (Earth-2: Post-Crisis)

Dr. Henry King Sr. (October 12, 1971 – 2020) was a member of the Injustice Society of America, the criminal known as Brainwave and the father of Henry King Jr.. His ability was part of the plan of Project New America where he planned to use his powers to change everyone's mind regardless of the casualties.

Gaining his powers
Decades ago, Henry was a neurosurgeon and started to develop ways to improve human brain. However, the hospital he worked in refused to fund him and he started experimenting on himself. Eventually, he gained multiple brain related powers and stopped a mugger by accidentally killing him. After his first time using the powers, he started to hear different people's thoughts and realized that they are all "monsters". Henry later used his powers to kill those "monsters" one by one.

Later, Henry fell in love with a women and had a son who also gained the same powers as Henry by heritage.

At some point before or after Henry Jr.'s birth, Henry joined the Injustice Society of America and donned the name, Brainwave.

Final Battle with the JSA
Ten years ago, he joined the rest of the ISA and fought the JSA, specifically Starman in an abandoned church, successfully distracting him long enough for Icicle to fire an icicle at him, a blow that would lead to his death.

Hunting the new "Starman"
In the present day, he is a respected neurosurgeon at Blue Valley Medical Center. However this is just an act to cover for his activities as Brainwave.

After Courtney Whitmore attacked his son with the Cosmic Staff he thought that a new Starman had appeared to take down the ISA and went to confront her. Despite his best efforts though, Courtney was able to cause an explosion and escape before she could be defeated.

Later that night, Pat Dugan used an armor to take on Brainwave which failed until Courtney Whitmore, now Stargirl, fought him back. Later, Courtney fought Brainwave and took the advantage to shoot but she missed. Brainwave saw the chance and forced Courtney to lay down. Pat was worried and turn a flashlight at Brainwave which gave Courtney enough time to use the Cosmic Staff to our Henry in a coma.

Awaken
Few weeks later, Henry Jr. started to manifest his powers and communicate with Henry Sr. with it. Henry Jr. visited Sr. and killed their family attorney who wanted to gain Henry Sr.'s money from insurance. As the attorney dies, Henry Sr. wakes up and asked what happened.
