- Prime (STR 60, DEX 70, PSY 90). Ray guns and plasma rifles.

- Viper (STR 70. DEX 70, PSY 70). Plasma rifles.

- Green (short green alien)

- Hornet (red with pincers)
- Jackal (squat, orange, 2 legs)
- Viper (red with a cobra-hood)
From left to right is:
- Green
- Prime
- Hornet. Hornets will both seek targets and stand guard at key points.
- Jackal. The Jackal uses Storm weapons, which are high rate of fire explosive weapons. They can blast through a city or take down civilian units very quickly.
- Viper. Vipers will both seek targets and stand guard at key points.
- Squid. The squid has psi powers. With a successful psi attack (rings emit from the target's head), the alien AI will get updated with the location of all the units on the Terran/Civ team. They can then aggressively home in on units they couldn't previously see. An unsuccessful attack (purple particles) is good news, and alerts you to the presence of a Squid. Squids are between the Green and Prime in attack power.
- Spitter. The Spitter shoots a relatively low power green ray attack. Any Civ killed by the attack, becomes a Crawler. (Not pictured; purple color, looks like a crab.) Every turn there is about a 40% the Crawler will metamorphasize into a Spitter. Be very careful than you can become quickly overwhelmed in a Spitter mission, and be prepared to evac.
