- From Letters Page Episode 20 - Chokepoint
- Absolute Zero fights Highbrow during the TermiNation event- she's creepy; she has a giant brain and she has to stay in a special chair because of it (well, she had to stay in the chair until her brain was removed and put in a jar that hovers around her with a cable leading to her spine). She doesn't have any psychic powers or anything, she's just really really smart.
- From Letters Page Interlude 7 - Nemeses
- Why is Highbrow Parse's nemesis (so far we've heard about her in relation to Setback and Kismet)? Why is she not more of a major villain given her intellect? She doesn't lack the drive, intellect, or anything to be a major villain - she's just fairly new. She's Parse's nemesis because she's largely introduced as a intellectual threat and the two of them match wits during Vengeance.
- Highbrow bears a strong resemblance to both members of the Brain Trust, a villainous psychic duo who first appeared in the second issue of DC’s “Kingdom Come” miniseries.
- Highbrow may also be a gender-flipped variant of The Leader, the high-foreheaded nemesis of the Incredible Hulk. The weapon she is shown holding on The Sentinels' card "Blackout" seems reminiscent of the Leader's odd-looking inventions.
