^{Bizarre Alien Senses - Frequently correlated with Eyeless Face. One way to make an alien creature seem bizarre to human audiences is to have it detect the world around it with a different array of biological senses than us. Often they're depicted as using sensory mechanisms found in other Earth species, such as echolocation, thermographic vision, or sensitivity to electrical impulses or vibrations.}

^{Playing With Syringes - A Mad Scientist, Mad Doctor, or Evilutionary Biologist, possibly supported by The Syndicate and/or The Government, will run a series of classified experiments to create something — often without regard to the well-being of the often-living test subjects, and the words "moral", "ethical", or "safe" will not be in the head scientist's vocabulary.}

<sup>Made of Good - Positive emotions and virtues like love and gratitude usually are not physical concepts. You can't see them; you can't feel them.

But they are now! These objects are materialized out of good feelings. Whether they power you up, you need to collect a bunch of them for some purpose, or they make a weapon for you to use, they are physical manifestations of goodness. On occasion, you may find a living being made of it. Conceptually similar to things made of Pure Energy.</sup>
