Alien hybrids and other lifestates

If you have a mermaid and alien have a baby , it could possibly be mermaid but with alien features (without the alien ability’s ) & vise versa. If you have a vampire with an alien, it could be a vampire with alien features & vise versa. Sadly we don’t have hybrids in this game & hopefully one day it might be possible

I can't check ingame right now but if I remember correctly half-aliens can become vampires /spellcaster /mermaid. I think this is because half aliens are practically normal sims, except for their looks.

@QueenMercy - if your human Sim has children with an alien Sim, and the child is hybrid (has alien skintone but is not marked as alien in CAS), then they should be able to be vampires or spellcasters or even mermaids. These types of "hybrids" aren't really hybrids. They game reconizes them as human with alien skintone, so if you want them to eat mermaid kelp or be a spellcaster, that should be possible. The only way it's not possible is if they child was born alien.

To make a hybrid sim, you need to press Ctrl Shift C on your keyboard.

I reconmend to select the day pobia, guilt drink & lack of slumber weaknesses.

Warning Don't have bathtubs in your sims residence only showers, it glitches the mermaids.

Oh and have fun with your Hybrids.

Occasionally a bug within the game allows it to create a hybrid on its own. In my current save file, I have a sim whose parents were a mermaid and a witch, respectively. The hybrid sim, currently a teen, is both. She has a permanent tail because of the glitch mentioned above by SERVERFRA.
