I doubt these are 100% viable as PC aliens. But if you wanted to, here are the stats. Descriptions HERE.
1. THE ELECTRIC-TENTACLED SPECIES
- 6d10 + 10 STRENGTH
- 4d10 SPEED
- 7d10 COMBAT
- Natural weapons deal 2d10
- 150kg, 4m long, very flexible
- Electrical sense functions as bioscanner in water and can stun small prey.
- Communications by electrical signals
- Slow movement out of water, average movement in water
- Temperatures over 0C are uncomfortably hot, temperatures over 10C are lethal in hours.
- Ammonia-H2O solvent biology incompatible with most other DNA-RNA life.
2. THE SOLITARY SPECIES
- 2d10+50 STRENGTH
- 3d10 SPEED
- 7d10 INTELLECT
- 7d10 COMBAT
- +10% to armor and body saves
- Enormous (1000kg) and many-limbed -- natural weapons deal 4d10
- Communication entirely by means of body language and writing; no spoken language and limited ability to rapidly process same.
- Stunted social processing and very little empathy or theory of mind.
3. THE TINY TYRANT SPECIES
- 3d5+5 STRENGTH (a further +5 to HP)
- 6d10+20 SPEED
- 5d10 INTELLECT
- -5% to body saves, +5% to fear saves
- 7kg, capable of flight and a skilled climber
- Immune to all but the most horrific DNA/RNA-derived diseases.
- Can eat human food with no issues.
- Cannot fly in body armor and cannot use human-sized weapons.
WEAPONS:
4. THE WHITE-FEATHERED SPECIES
- 8d10 STRENGTH
- 6d10 - 3 COMBAT
- +5% to body saves
- [-] on checks involving intermediate-scale manual dexterity that require some force (picking locks with one's tongues is easy but carpentry is very hard); some gross motor tasks can be done with bendy feet
- Carrying capacity double human
- Superior speed, can't climb
- Natural weapons deal 2d10
- 400kg, much more flexible joints than terrestrial animals with a similar body plan (i.e. ungulates)
- Blind but can smell, taste, and hear with its feathers (putting one in a space suit or heavy armor is likely to go badly and should usually lead to a panic roll).
WEAPONS:
4. THE BOWER-BUILDING SPECIES
- +10% to body saves
- 6d10 -3 SPEED
- +5% armor
- Carrying capacity double human
- Natural weapons deal 1d10; DNA/RNA life must make a body save at [+] or roll at [-] for the next 2 rounds due to mild stinging venom
- 200kg
- Below-average speed, too dense to swim
- Can eat human food
