Basic Trope: It is impossible to coexist with the enemy, they must be exterminated for humanity to survive.
- Straight: The Frib are obsessively dedicated to the extermination of humanity, and must be wiped out to keep them from succeeding.
- Exaggerated: The Frib legitimately explode around humans, so their homes must be nuked into nothingness, and not a single human seems to find problems with it.
- Downplayed: The Frib cannot be negotiated with, but can be contained without exterminating them.
- Justified:
- The Frib were created specifically to destroy humanity.
- The Frib are so so bizarre and incomprehensible that any form of peace or agreement is impossible. Their morality, biology, and psychology is incompatible with our own. They feel the same way about us.
- Inverted: The Frib are symbiotes that humans cannot live without.
- Humans are left disgusted that they must band with the Frib to survive despite their completely abhorrent morals.
- Subverted:
- The Frib and humanity both badly misunderstand each other. Once lines of communication are opened, the war ends quickly.
- Humanity exterminates the Frib without a second thought. Years later, when they're not in any danger, they begin to romanticize the Frib, and demonize the leaders responsible for their destruction, believing that a peaceful solution could have been found.
- It seems like total extermination is necessary, until a Defector from Decadence shows up and asks for humanity to stop their outright genocide, and to instead help the defector overthrow his own genocidal government so there can be peace.
- Humanity and its war against the Frib is initially is portrayed in a purely heroic light, but then... wait a minute... why are the humans wearing all these weird uniforms? And what's with all these rumors about people hiding Frib in their attics? Oh. Oh no...
- Double Subverted:
- ...but this is just a ruse intended to lull humanity into a false sense of security.
- ...that is, until the Frib come back somehow. All pro-Frib sentiment instantly disappears, and another extermination war ensues.
- ...but the defector's enemy is a Master Race that does have to be wiped out and will not negotiate so the Slave Race the defector is from can be free.
- ...but still, just because the humans are evil monsters, doesn't mean the Frib Empire isn't much better. In fact, the humans are the least worse of the two.
- Parodied: Coexistence with the Frib is impossible because they are extremely annoying; they must be exterminated for humanity to finally get a good night's sleep.
- Zig Zagged: Depending on the Writer, the Frib may or may not be totally evil and need to be destroyed.
- Averted: Humanity and the Frib get involved in a nasty war, but manage to resolve things diplomatically and live in peace.
- Enforced: The writers need to have a dangerous threat to humanity, but don't want to think much about ethics or the chance of a peaceful resolution.
- Lampshaded: "Are we really gonna have to kill all of these things?
- Invoked: Evulz creates the Frib specifically to try to relentless to kill the The Pax knowing they'd fail if they'd resist. Previous attempts with The Undead failed as they had no qualms with destroying them. The Grox killed a third of them before feeling guilty and joining them after likewise choosing to throw themselves in front of weapons rather than kill again. Either they'd be corrupted to something more exploitable or they would allow themselves to be wiped out.
- Exploited: Evulz manages to turn The Federation against humans by pointing out they killed the Frib.
- Defied: Even though they are extremely dangerous, human scientists find a way to make the Frib lose interest in exterminating humanity.
- Discussed: "Some species you can reason with, sit down and work out a peace and live together. The Frib aren't like that."
- Conversed: ???
- Implied: Human historical records casually mention a race called the Frib that was exterminated by humanity; no one seems to be bothered by this incident at all.
- Deconstructed:
- The Frib civilization nearly collapses because they are too focused on such a difficult and impractical goal.
- Such a war is still genocide and carries a plethora of moral dilemmas alongside it. Sure, maybe most of the Frib are irredeemably evil, but what about the inevitable My Species Doth Protest Too Much? Should they be put on the chopping block, too, just for being Frib? For that matter, can you even be sure you've spared them all if the answer is "no"? And what about Genocide Backfire and things like that? There's so many ways it could turn worse that it's almost certainly not guilt-free anymore.
- Reconstructed: ...but the rest of the galactic civilization supports them, because they consider humanity to be a threat.
