As a plot description, NextWave was about 5 heroes who find out the top-secret organization they're working for (Highest Anti-Terrorism Effort), and its corporate sponsors (Beyond Corporation), are creating all sorts of dangerous weapons. So they go rogue, stealing a ship and traveling the country, attacking various installations of freaky crap.
In practice, NextWave seemed to be about Warren Ellis giving Stuart Immonen lots of fights between angrily sarcastic heroes and weird and/or cool shit to draw. As one of the caption boxes says after a sequence of kicking and exploding things, "This is what they want!"
The "they" in this scenario I assume applied to the readers. The readers say they want action, they want fight scenes, they want cool one-liners and all manner of weird shit? Well unhinge your jaw, because Ellis and Immonen are jamming a funnel down your throat and pouring in all you can take.
So, of course, the book sold like crap. There were no crossovers! No guest appearances from more popular characters! No event tie-ins, unless you count the cover for issue 11, which proclaimed it "Not Part of a Marvel Comics Event", and featured Machine Man holding a sign that read, "Mark Millar Licks Goats" (Those poor goats.)
It was just a book about five characters running around blowing up stuff like samurai robots, or Mindless Ones summoned by the Dread Rorkannu on behalf of the Beyond Corporation in exchange for $100 and some of those "Suicide Girls." Clearly, it wasn't making any attempt to take itself seriously, even if the characters were (to the extent they were capable of taking anything seriously.)
The best known character was probably Monica Rambeau, formerly Captain Marvel the 2nd, now a grouchy woman trying to use her limited cred as having led the Avengers to ride herd on 4 lunatics. Or maybe original X-Forcer Boom-Boom, who just goes by Tabby in this book, and gets written as a sort of Valley Girl idiot. Actually kind of weird reading that New Warriors Annual last week and she's shown to know her way around computer databases. Not no more she ain't! Machine Man calls himself "Aaron", and is an arrogant, drunk, robot. Ellis turns Elsa Bloodstone from a Buffy knock-off to Hellboy crossed with the Punisher, combined with an acerbic British attitude. The Captain was a new character, and was just some loser from Jersey who got powers from dumb aliens, who he then kicked the crap out of because he was drunk and thought they were leprechauns. His best moment was probably beating Rorkannu's skull in with a toilet.
They argue all the time. Tabby gives Elsa grief about a European Union shirt (which Ellis later uses to mock the, "Do you think this A on my head stands for France?" line from Ultimates. Which, to be clear, deserved to be mocked.) Aaron keeps calling everyone else "fleshy ones", and at one point gets the shit kicked out of him by the 3 women on the team. The Captain's a dope that everyone barely tolerates and no one worries when he gets smacked over the horizon. It's a workplace comedy, but they all really dislike each other. They just hate Beyond Corp more.
It's a very early-2000s style of humor. They're being chased by Dirk Anger, a parody Nick Fury who yells angrily all the time and keeps trying to kill himself through methods like sitting in a chair staring down the barrel of a revolver the size of a tank, as some kind of gag about masculinity issues or repressed homosexuality or something. Beyond Corp throws a bunch of knock-off Avengers at them, including a guy who got Captain America powers because Rogers took a whiz after the procedure, and the super-soldier serum was still viable in that form. Another guy got Hulk powers because he tried to huff gamma-irradiated nuclear waste. They're led by Forbush Man, who makes a lot of proclamations about how mighty he is, especially with the girls.
I can't remember laughing a lot when I bought the entire run at one of the first Cape-Cons. Either I didn't get the joke, or (more likely) I didn't read it as a joke at all. I was mostly just impressed at all the strange things Immonen and Ellis came up with for them to fight. And Immonen draws the heck out of all of it. Forbush Man uses the power of his "Omni-Mind" to send each member of the team into some ugly alternate reality, and Immonen shifts his art style for each. So he draws Elsa's nightmare world - where she wasn't diligent enough exterminating monsters and they've overtaken the world - in a faux-Mignola style. (Tabby was unaffected by Forbush Man's power, because she's too dumb, you see.) Issue 11 has 6 consecutive double-page splashes, including the one up there, of NextWave just tearing their way through things like brontosaurs with optic blasts, or MODOKs that are Elvis (and shoot cheeseburgers.)
Of course, the last one has the tagline, "nextwave: blatantly wasting your money since 2006." But it's only a waste if I feel ripped off. Relative to a Bendis comic where the artist only gets to draw people sitting around talking about nothing that couldn't be handled in 2 pages or less, this was a steal.
Bits and pieces of this series have leaked into larger use around the Marvel Universe. Elsa Bloodstone most obviously. She seems to be getting used in some book, somewhere, pretty much constantly, and it's always Ellis' version. Although I think most writers leave out an element of enjoyment she gets from her work that we see here, in the shooting and decapitating robots with shovels.
I don't see a lot of Boom-Boom these days, but I think the "Valley Girl" characterization kind of stuck. Brian Reed used this version of Machine Man in Ms. Marvel volume 2, but when Jeff Parker added the character to the cast of Red Hulk a few years later, he went back to the classic look and characterization. But it was a Red Hulk book, so who gives a shit, really? Al Ewing used Beyond Corp in one of his Avengers books (I think Luke Cage and the Mighty Avengers), as did the Amazing Spider-Man writers between Nick Spencer and Zeb Wells' runs.
Monica was part of the cast in Ewing's book, so when Beyond returned, so did the trench coat and "Auntie Monica" nickname. The trench coat was also part of Monica's look when Kelly Sue DeConnick used her in Captain Marvel volume 7. I think most writers who've use Monica since NextWave give her a bit more of a blunt approach. Take no shit, don't defer or get pushed around. So maybe she's a case of gradual bleed into the character, rather than a wholesale revision like Elsa and Tabitha got.
The Captain, I think may have vanished entirely. I guess there's no place for a super-strong, flying idiot in the Marvel Universe. Or, he's not the type to save the day unless someone's cutting a check.
