JACK You have the Power to Sample At the start of the game draw five
additional powers. At any point during the game you may use one
of these extra powers. You have use of the power until the end
of that challenge. At that point, you must set the power aside,
and you may not use it again.
Every time you gain an external base you may draw an additional power
from those not being used and add it to your cache of samples. When
you lose a base you must discard a power that you have not sampled.

The Warp Alien Power database has over 2000 entries you can look through, including every offically printed alien (search by author, origin, expansion, variant, and more). Just click on "Homebrew of the Day" to access the Amazing Alien Database. If you play Cosmic Encounter long enough, you eventually find yourself in The Warp.
Normally, you wouldn't find this many zombies in the warp...
