Hank King is the son of one of the
JSA's most psychotic villains: Henry
King, the original Brainwave. His
mother was the original Star-
Spangled Kid's sister, Merry
Pemberton (aka Merry, Girl of 1000
Gimmicks), a minor super-herione
active during World War II. For
reasons yet to be revealed, Merry
disappeared when Hank was a small
boy, Leading him to believe she was
dead.

Although Hank inherited his father's
telekinetic and telepathic abilities, he had
seemingly inherited his mother's values
and morals. Hank donned a version of his
father's Brainwave costume and, as
Brainwave Jr., joined with several other
JSA offspring to form the shortlived team
Infinity Inc. Determined not to follow in his
father's footsteps, Hank gave it his all as
a hero, winning the respect of his father's
enemies and the affection, for a time, of
one of their children (Jade, the daughter
of Green Lantern - now Sentinel - Alan
Scott).

During a final confrontation with the original Brainwave, Hank's power level was increased
tenfold when his father, seemingly gerforming an act of goodwill before his death,
bestowed upon Hank his superior mental powers. With his father's ability to to project life-
like three dimensional images and psionic beams, Brainwave is one of the strongest
telepaths on Earth.

Recently, Brainwave was committed to Arkham Asylum following several violent mental
breakdowns. It has been speculated that the power Brainwave received from his father
was the catalyst for his insanity, but this is not entirely true. Something else has been
infecting his mind....something powerful. Arkham will not hold Brainwave prisioner much
longer.
