If you have spent any time in the game FTL: Faster Than Light, you probably encountered one of these:

Zoltan are humanoid beings mostly composed of pure energy, giving them their unique glowing aura. Due to the nature of their bodies, they have the ability to power up nearby electrical objects and machines. While the Zoltan do not look as threatening as other alien races in the universe of FTL, they do however explode in a violent discharge of energy upon recieving damage and dying.

While they can cause damage to others nearby due to their instability, the Zoltan themselfes probably suffer the most because of it: The constant fear of not just dying and exploding but also potentially harming someone you like must be excruciating.

Note: This skin was my original entry for the "Aliens : Skin Contest". I decided to create a new one instead: Hypnosquid
