Merry King (Earth-2: Post-Crisis)

"It's always hard when the family finds out. Gets involved. My sister, Merry, she did. Henry's mom, right? Merry Pemberton. Brainwave killed her."

- Sylvester Pemberton and Yolanda Montez

Merry King (née Pemberton) was the sister of Sylvester Pemberton and the wife of Henry King Sr.

Meeting Henry
At some point after Henry acquired his powers, Henry robbed a bank and Merry, as the Girl of a Thousand Gimmicks, went to stop him. Henry then read her thoughts which he thought were different from normal people. Henry then fell in love with her, and she gave birth to a son.

Death
As Henry Sr. later joined the Injustice Society of America, Merry was killed by him and Henry tried to blame Jordan for it.

Legacy
In 2020, Henry Jr. found out the videotapes of his father about his life after he got powers. In the one after Merry was killed, Henry blamed Jordan for the death which caused Henry Jr. to think Jordan was the murderer until Henry Sr. told him he is the actual killer.
