Time marches on in most parts of the galaxy, and it's never a bad idea to look to the future. Here are some species that fit the following criteria:
  • Reasonably broad appeal as potential main or supporting characters.
  • Images of them are very easy to find or make.
  • Lifespans are long. Arbitrary threshold: Ultimate Alien Anthology tables show an upper bound of at least 70 years under 'Middle Age.'
