These mechanics apply to all Skrell.
- Skrell have their own language that can be used by typing ,k before anything you say, and can also be used over the radio.
- Skrell can use a variety of different psionic abilities.
- Skrell can enter Srom with other Skrell when they sleep, allowing communication and lucid dreaming.
- Slimes are naturally passive to skrell for a mysterious reason science has yet to find out.
- Skrell have the ability to breathe underwater due to them being amphibious.
- Due to their advanced vestibular system, Skrell maintain a good balance and never slip.
- Skrell have large heads with protruding headtails and due to this, they cannot wear normal EVA helmets but instead need to wear Skrell helmets (found in EVA or by using a suit cycler). Their headtails also make it uncomfortable or even impossible to wear normal headwear such as hats so most Skrell opt-out of that.
- Skrell have a hemocyanin-based circulatory system, meaning that their blood is instead bound to copper atoms and not iron atoms. Skrell require copper supplements to alleviate blood loss symptoms.
