# Brainwave (character)

Brainwave or Brainwave Jr. (Henry King Jr.) is a character in the DC Comics Universe, who is commonly portrayed as a superhero and son of the supervillain, Brain Wave, along with primarily being a member of the Infinity, Inc.

## Publication history

Brainwave first appeared in All-Star Squadron #24 (1983) and was created by Roy Thomas, Jerry Ordway and Mike Machlan.

## Fictional character biography

Hank King Jr. is the son of Hank King Sr. and Merry Pemberton. As the second Brainwave, he is a founding member of Infinity, Inc., creating the group to bring honor to his family name. During the run of Infinity, Inc. Brainwave develops a relationship with Jade. He also absorbs his father's mental powers following his death, increasing his own powers and driving him insane.
Brainwave resurfaces years later as a member of the Legion of Doom. He is possessed by Mister Mind, who feeds on his mental energy.
In Justice League: No Justice, Brainwave joins Task Force XI, a team of psychics assembled by Amanda Waller to battle Brainiac.

## Powers and abilities

Both King Sr. and Jr. have a variety of mental powers. King Sr. was originally much stronger, but upon his death, he somehow passed his powers on to his son, vastly increasing King Jr.'s power level.
Chief among their powers is telepathy. Both are able to dominate many minds at once and cause people to see illusions, or even have complete control over them. Proximity seems key to the effectiveness of this power, even though it had no defined range. King Jr. mentioned how even strong wills could not resist him when he was right next to them. While many telepaths filter out the thoughts of others, King Jr. allows the millions of minds he constantly comes across to flow freely through his mind.
Lesser-used powers of the Kings include telekinesis, the creation of realistic three-dimensional holograms, and the ability to fire blasts of psionic energy.

## Other versions

An alternate universe variant of Brainwave from Earth-2 appears in The New 52.
