I'll divide this into two sections.
Section one: Yet to be repaired, or lacking a power supply.
Section two: Repaired and functioning.
1.
Light manipulators:
The light manipulators are a device only given to high-ranking Cel of the military. They are built into the forearms and allow the user to... Well, manipulate light. It could be anything from a heated beam, to a hardlight shield. Most use it almost entirely for the latter, because it requires some degree of focus to use.
Short-range telepathy:
Yet another device heavily employe by the Cel military, it allows telepathic communication with any creature within thirty feet.
Regenerative Alloy:
The name for this technology is rather misleading. The alloy itself isn't what regenerates, it is actually millions of nano machines that use nearby and compatible metals to repair their owner.
The Siren's multitool:
It would be functioning properly, if it had enough charge to work. The multitool is a simple Cel multitool that generates hardlight to become different tools. At least, that's what it's supposed to be. The Siren has tinkered with it and it now is a hacking device, a lockpick, and a simple scanner.
2.
Her blade of choice:
It's made of Cel alloys, and is rather durable because of this. The sword is modeled after the human katana. She has trained with it for several years during her time as Arbiter of the Cel.
Shielding:
Every Cel soldier is equipped with a light, personal shield. Every high-ranking Cel soldier is equipped with a high-power shield projector that is installed on the chest. Right now, The Siren's is only functioning at a very low capacity. It doesn't hold up to much. What it does do is disguise her as a human.
Enhanced AI:
Every Cel is constructed with a simple AI core to make them function, and is given an upgrade to make them intelligent. If immobilized, "turned off", and opened up, one could take this upgrade and strip her of... everything. Intelligence, emotions, memories, independence.
