You go see GWAR, people die. It's as natural as rain on Sunday morning.
"It is I, ODERUS URUNGUS, lead singer of the sickest band in metal history, Earth's only openly extra-terrestrial rock band, and the destined destroyers of not only the human race but also reality itself. GWAR! Hulking, heaving, dribbling WAR-GODS who like nothing better than putting hordes of our sniveling fans to the sword while playing the marauding mutant metal that we are famous for! Star's of stage and screen, carvers of stem and spleen! GWAR LIVES!" — Oderus Urungus, GWAR Mythos''
X-Sheriff "Tubb" Tucker:note Casey Orr, a.k.a. Beefcake the Mighty Nobody's gonna take my gun, I'm gonna keep it til the end, yeah Nobody's gonna touch my gun, or I'll shoot you in the face! Yeah it's a killing machine, it's got everything Yeah, got that magnum power, license to kill everything!
Creation Myth: GWAR created the human race by having sex with apes. The Master was not happy about this, so He froze GWAR in antarctic ice.
"Approximately 40 billion years ago, the Master of all Reality took a shit, and thus the universe was born. But that was not enough. He had to wipe. And what better way to wipe than with war? So he created the Scumdogs of the Universe."
Crowd Song: "Sick Of You". Also, when it's done live, the audience shouts out the answers to the questions in "Slaughterama".
Deadly Game: Slaughterama. Because when your life is shit, you haven't got much to lose.
"My quest for sex consumes all my life Being a God I do what I like"
Evil Versus Evil: On their quest to destroy all existence, GWAR often faces off against and destroys other evil entities.
Fictional Political Party: Their album War Party centers around a political party (named "The War Party") that supports policies dedicated especially to the eradication of the human race through global war and hatred. The party's symbol is said to be the "Krosstika," a combination of the Christian cross and the Nazi swastika, representing "two great hates that hate great together." According to GWAR lore, the political party has since disbanded.
Godzilla Threshold: During the Beyond Hell tours, GWAR has been beaten down and sodomized by Jewcifer. There seems to be no hope, except for when Gor-Gor comes and eats Satan. Gor-Gor then tries to eat GWAR, but is killed by Oderus.
High-Pressure Blood: A staple of their live shows. Lampshaded by Sleazy P. Martini in "The Gwarnage Campaign".
"Wow, look at all the PSI in his main aorta artery."
Humans Are Morons: "Back on the road, it's no lie, stupid fucking humans pay money to die."
I Am the Band: Dave Brockie, aka Oderus Urungus, as he was the only remaining founding member and the idea of the band was his in the first place. In fact, several characters in the band have had multiple people play them. With Brockie's death, the future of the band is unknown.
Shout-Out: "The Salaminizer". Sung to the rhythm of "Gangsta Gangsta" by rap group NWA. Dave Brockie enjoyed NWA's work and decided to put his own spin on it.
Following the same concept, "Think You Outta Know This" is basically "Give It Away" by the Red Hot Chili Peppers with a Badass Boast (or rather, a series of them) by Sleazy P. Martini.
Urungus's penis is named after Cthulhu. The band also fought Yig regularly early on.
Squick: From showering their audience in fake blood and semen to songs like "Fuckin' An Animal", GWAR runs the gamut of stomach-churning.
A nice example from "Bloody Mary", the lovely phrase "Her womb explodes in a meat maggot mesh".
Step Up to the Microphone: On several of their albums, Beefcake will sing lead vocals on one song instead of Oderus. "Release the Flies" from Lust In Space was sung by Flattus Maximus. They also have several songs where Techno Destructo, Sleazy P. Martini, Sexecutioner or Slymenstra Hymen will sing lead.
The Show Must Go On: During Tour De Scum GWAR had protesters on stage who blocked the show from happening. After asking if they are in show business (no? Well then get the fuck off the stage!) Sleazy P. Martini declares the show must go on.
A serious version of this trope occurred when Cory Smoot (AKA Flattus Maximus) died while on GWAR's Fall 2011 US tour. Shortly after his death, Dave Brockie announced that the tour would resume as planned and that the character would be retired permanently in honor of Cory.
Take That: They bring celebrities and politicians on stage for ritualistic public execution.
Oddly enough, Oderus considered being killed by GWAR to be flattering.
Take That Me: When not taking pot shots at Earthlings, celebrities, American culture, etc, they take shots at themselves for being less-that-stellar musicians (at least in the early days), making fun of their cheesy props, etc. Not to mention they portray their characters as rather dim and bufoonish.
Meta, Dave Brockie maintained a blog on his website called "Stupid Shit That I've Done." It's Exactly What It Says on the Tin. Even by GWAR standards, it's some impressive stupidity (usually involving drinking way too much).
One of the victims in Slaughterama is a Nazi skinhead.
Wharghoul is about an American zombie troop who joined the SS.
Sonderkommando's title is taken from death camp units.
KZ Necromancer mentions Mengele and a plot to save Hitler's semen.
Poor Ole' Tom was killed by Nazi skinheads.
Hitler's vomiting face and a Nazi soldier were in the flesh column.
Beyond Hell (and the tours following it) featured a half Hitler half Jesus. Jesus was a dick, but Hitler was (in Orderus' own words) pretty cool.
Ties into the song "Krosstika" from the War Party album, which states that "The swastika and the bloody old cross" are "Two great hates that hate great together"
Dave Brockie had pissed on Hitler's Real Life grave.
The Rival / Unknown Rival: In their fall 2013 tour with Whitechapel, Oderus brought up that Rob Zombie got GWAR thrown off the 2013 Mayhem Festival line up. This resulted in Oderus taking shots at Rob Zombie throughout the concert and yelling "FUCK ROB ZOMBIE!" Whether this is true or the band trying to stir up some drama is unknown though.
