Nightwatch is a fictional super hero who has appeared in various comic book series published by Marvel Comics. He exists in Marvel's main shared universe, known as the Marvel Universe.
Publication history
Most of his appearances came in the 1990s in various titles starring Spider-Man and in his own short lived, self-titled series. One of his more prominent roles was in the Maximum Carnage crossover.
He first appeared in Web of Spider-Man #99 - less than a year after Todd McFarlane's Spawn, whose costume the armor resembles suspiciously strongly down to the prehensile cloak and self-repair abilities.
Fictional character biography
Nightwatch was Doctor Kevin Trench, who witnessed a costumed man die battling some terrorists armed with invisibility-generating 'cloaking" devices, and unmasked the corpse to learn that it was an older version of himself. His first appearance was in Web of Spider-Man #99.
Freaking out, Trench stripped the costume from "his" body and fled to a deserted island, reasoning that if he just never wore the suit or went home, he wouldn't die. Events conspired to bring him back, as the criminal Alfredo stole one of the costume gloves after washing up on the island and being nursed to health by Trench. After Alfredo had been dealt with, Trench decided that he couldn't avoid his destiny, and decided to investigate the costume's origins.
In the interim, he battled menaces like the "Maximum Carnage" gang, who were wreaking havoc across New York and slaughtering dozens of innocent civillains. He had many allies in the fight, including, but not limited to, Captain America, Black Cat, Deathlok and Firestar. He also fought the mutated Deathmask. Graduating into his own book, Nightwatch encountered similar "cloaked" villains, and was shocked when their technology merged with and enhanced his costume. 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.
Ultimately, project head Phillip Morelle proved to be recklessly conducting nanotech experiments to make a replacement skin for his dying son Justin. Nightwatch fought his way onto Phillip Morelle's space station to confront him but not before Phillip sends two assassins into the past to kill Nightwatch using his nanotechnology to open a time portal. Much to both Nightwatch and Phillips surprise that same time technology allows a future version of Justin Morelle to travel into the present. Future Justin, armed with a more advanced version of Nightwatch's own suit, kills his father and reveals that the nanotechnology his father was developing produced a dangerously unstable energy matrix that in his time line devastated North America killing billions. Justin upgraded Nightwatch's armor to its final evolution and the two of them worked together to destroy the space station before the disaster could happen. In the epilogue present day Justin Morelle, the son of Phillip and Trench's ex, received the nanotech skin from the project as his father had dreamed. Seeing his ex happy with her healed son Nightwatch chose to travel into the past and complete the time loop with Cardiac's help, ensuring his own death but also ensuring the cataclysm timeline would never come to pass ensuring this happy ending would be the true timeline. The series ends with Kevin's trip into the past while future Justin's fate remains unclear.
Retcon Death
In an editorial oversight Nightwatch, back in his pre-future tech suit was an innocent victim of the Great Game. While trying to protect Justin, he was slain by the mercenaries Polestar and El Toro Negro. Polestar used the magnetic powers of his costume to peel away just enough of Trench's nanite costume for El Toro Negro to shoot him point blank in the chest. El Toro Negro then immediately turned on Polestar, shooting him between the eyes.
Nightwatch survived but knew he had been fatally wounded, and used the last of his costume's power to go back in time and try to warn his past self of what would happen, to keep him from meeting this ignoble end, and try to prevent his girlfriend's death in the process. Ultimately, he got sucked into a fight with terrorists and ended up fulfilling the time loop, dying before he could warn himself.
Reappearance
Kevin Trench reappears in street clothes at the newly-established law practice of Jennifer Walters, a.k.a. the She-Hulk, regarding a legal case naming several costumed superhumans, including Walters and Trench, that an as-yet-unrevealed agency seems determined to keep unresolved. No explanation is given regarding Trench's previously established "deaths"; instead, he is stated as "keeping....an extremely low profile", using the Nightwatch nanotech sparingly while maintaining a medical practice and doing charity work. 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. A few days later, he calls Walters and informs her that he has spread word of her fledgling law practice to other "guys from back in the day--people like me who took what they could from the [superhero] game and moved on", bringing an influx of new potential clients to Walters' office.
Powers and abilities
Nightwatch's costume boosted his strength and durability by triggering his adrenal glands, and nanotechnologically repaired itself. His cape responded to his subconscious thoughts to move on its own to attack his foes as well as allowing him to glide on air. After he was boosted by the later-generation Morelle technology, the durability of the costume increased, the cape became more metallic, and he had something closer to true flight in addition to increased speed and eventually nanotech cutting blades.
