Doctor Kevin Trench, upon witnessing a costumed man seemingly die battling some terrorists armed with invisibility-generating 'cloaking" devices, unmasked the body afterward to learn that it was an older version of himself.

[1] As the superhero Nightwatch, Trench battled menaces such as the "Maximum Carnage" gang, who were wreaking havoc across New York and slaughtering dozens of innocent civilians.

[volume & issue needed] Graduating into his own book, Nightwatch encountered similar "cloaked" villains, and was shocked when their technology merged with and enhanced his costume.

[4] In between battling menaces like Flashpoint, Cardiac (whose technology had been stolen to create the more vicious Cardiaxe), and Venom, Nightwatch discovered that an old ex-girlfriend was working for the shady Morelle Pharmaceuticals on a nanotech project.

[volume & issue needed] Ultimately, project head Phillip Morelle proved to be recklessly conducting nanotech experiments to make a replacement skin for his dying son Justin.

the She-Hulk, regarding a legal case referred to only as "the blue file", involving several costumed superhumans, including Walters and Trench, which an unrevealed agency seems determined to keep unresolved.

He aids Walters in beating back a sudden assault from grotesque creatures, donning the Nightwatch helmet and manifesting tentacles from the inner surface of his trench coat.

Eventually wishing to become a lower-level superhero for selfish reasons – realizing villains never "win" and that "heroes" are ensured respect, money, power, and a comfortable and safe retirement – Trench hired Doctor Druid, The Shocker, and Vibro to aid him in casting a powerful spell that effectively "retconned" all memories and all existing documented history into believing that "Nightwatch" had worked for years in the superhero community.

It was so successful, however, that when it was complete, four heroes who had been trying to save the town – She-Hulk, Tigra, Monica Rambeau, and Wyatt Wingfoot – immediately joined Nightwatch in bringing Druid, Shocker, and Vibro to justice.

She was able to use this document (and her own unexplained mystic powers) to break She-Hulk and her team of their convictions in Nighteater's false history, and that he has later arranged for the lone survivor to be killed.
