List of Aliens in Beyond Earth. These are indigenous alien species. For designer lifeforms see the list of Harmony units.
|Wolf Beetle||2||10||0||0||Swarm organism that constantly defends alien hives by patrolling around them closely. Carpets landscape in mass swarms when Alien aggression is ignited.|
|Raptor Bug||3||16||0||0||Fastest known land alien species, with greater strength compared to a swarm of Wolf Beetle. Appears only when the aliens feel threatened.|
|Siege Worm||1||62||0||0||Migrates between several destinations, destroying any infrastructure or units in the lands they pass through, extremely effective against cities. Does not become actively aggressive or specifically move through or towards human construction until the aliens are particularly pressed.|
|Drones||3||10||0||0||Only known Alien unit capable of flight. Has similar abilities to the Wolf Beetle but does not benefit from terrain bonuses.|
|Manticore||1||4||2||10||Chemical spewing "infantry" of the Alien Hive. Commonly found stationed within the hives themselves to attack targets that close in. Appears in greater numbers if Alien aggression is continued after the first Wolf Beetle swarms.|
|Sea Dragon||2||16||0||0||The oceanic relative of the Raptor Bug. Much more voracious in the fact that it regards all naval vessels as possible prey.|
|Kraken||2||56||0||0||Aquatic relative of the Siege Worm, behaves similarly in all fashions. Will form "pods" similar to Earth-based cetaceans, making them deadly to take on even at the highest combat levels.|
|0||0||A combination of terrain and enemy presence. Does not move or attack, but has ability to spread hydrocorals on adjacent fields. Occurs in different stages of growth. Dangerous in melee, but vulnerable to distant attacks.|
|Makara||2||28||0||0||An amphibious alien, capable of crossing both land and sea. It is slow and pillages any improvements it walks on.|
|Ripper||3||8||0||0||Most commonly found water alien. Appears in large groups, patrolling oceans. Althought not very dangerous, attacking and killing it may enrage all aliens on a planet.|
|Scarab||2||6||0||0||Weak, land organisms, similar to wolf beetles.|
- ↑ There are three levels of hydracoral. Level 1, has a strength of 10, level 2, 18, and level 3, 32.
