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.'
| SPECIES | UPPER BOUND OF MIDDLE AGE IN UAA | POTENTIAL IMAGES OTHER THAN CANON |
| Clawdite | 71 | Anything (shapeshifter) |
| Defel | 74 | Really any kind of shadowy werewolf thing |
| Togruta | 74 | Togrutas |
| Arkanian | 84 | Pale humans with white hair etc. |
| Ssi-Ruu | 90 | Various dinosaurs; Dragonborn from D&D |
| Falleen | 110 | Green-tinted humans; Cardassians or Orions from Star Trek |
| Wookiee | 350 | Wookiees |
| Shi'ido | 360 | Anything (shapeshifter) |
