Guile Hero - Not that Buck is a slouch when it comes to fighting, but his life and pay-check are always ultimately saved by his ability to think on his feet and play the entities around him against each other.
Badass - Fresh out of hospital, having had most of his body reconstructed from scratch, and still requiring a cane to walk, he still manages to fight 35 members of the PSmith collective to a standstill.
MacGuffin - Lampshaded and deconstructed. Three-fourths of known religions revolve around Its importance; nobody can agree on why. Wars break out as various races/beliefs fight over It, and there are disastrous repercussions.
Not entirely— they're pledged to each other, and Ettarre has the libido-inhibiting virus. Once she recovers, she jumps him in public, and the view quickly cuts to Buck looking away and Madam Dem Five looking pleased.
A Date with Rosie Palms - Apparently out-of-control hormones pose a health hazard. Ettarre has the libido-inhibiting virus, but Thad doesn't want to break his pledge to her by sleeping with someone else. Eventually he solves the problem by raiding a medical officer's Porn Stash.
Cute Is Evil — It turns out the Pogs are one of the races that worship the Winslow, and when they figure out humanity has it, they turn on their former allies, spreading a bio-engineered plague that saps the libido and eventually the mind in hopes of just taking it from humanity once they all go extinct. Despite this, they still look like happy, friendly little shell-less turtles.
Jerk with a Heart of Gold - Possibly even a Jerkass Fašade. They have devoted their race's skill with biotechnology to preventing biological warfare, possibly as a result of their involvement in the creation and enslavement of the Beemahs.
Planet of Hats - Relative to humans, at least, the Kleg are all irritable stingy jerks. Their other hat is biotechnology.
