Phos (Post Winter)

Abilities:

Immortality: As a Lustrous, as in gemstones brought to life through micro-organisms known as inclusions which power Lustrous by absorbing sunlight and turn it into energy. As such Phos does not physically age like organic beings do and while being the youngest of their kind at the start of the manga and anime they still became three hundred years old early on. Also as a Lustrous Phos can survive having parts of their body broken apart and even being shattered and, provided enough of them is put back together they become active again though certain kinds of damage can render Phos immobile, namely being shattered in two at the waist or losing their head. However even in the case of being shattered completely, so long as they can be put back together they can come back almost like nothing had happened.

Strong Inclusions: It's been theorized and observed by the likes of the Lustrous' doctor Rutile along with the leader of the Lustrous, Kongo-Sensei, that Phos has surprisingly strong inclusions with lots of potential that they initially could not show due to the fragile nature of the phosphophyllite that makes up Phos's body but that potential was awakened when Phos received replacements for their legs taken by the Lunarians, these new legs made from the agate spines and quartz taken from the shell of the Admiralbillis, Aculeatus at the behest of his sister and unexpected friend of Phos, Ventricosus, after the queen of the Admiralbillis had a change of heart in using Phos as a bargaining tool due to the bond she had formed with the gem. These replacement legs initially gave Phos incredible speed to where they could surprise Yellow Diamond, the fastest and eldest of the active Lustrous, though the elder was able to catch Phos and get them to where they could walk normally thanks to their experience. Later after performing winter duty with Antarcticite and losing their arms to the ice floes Phos would receive new arms made from gold and platinum alloys the two gems found that once their inclusions settled into were able to be used by Phos. However as a side effect Phos has lost a number of memories due to losing their arms and legs along with the inclusions that were stored in them. Phos would go on to lose more of their original body but that is a story for another day.

Agate/Quartz legs: As mentioned above Phos would receive new legs after their original legs were broken off and taken by the Lunarians after the gem was lured into an ambush by Ventricosus, the queen of the organic Admiralbillis in exchange for her brother, Aculeatus. However once her brother was free and fought off the Lunarian party sent to retrieve Phos the queen would have a change of heart due to the connection she developed with Phos during their interactions before they went into the sea. She would have her brother break off two spines off of his old shell which would be used by Rutile to make new legs for Phos as they were made of agate quartz due to the fossilization process the shell's spines had gone through. During this time Phos would develop incredible speed though they had trouble stopping and making turns along with initial trouble stopping themselves until they got aid from Yellow Diamond. However when their inclusions took in the gold and platinum alloy attached to them later on the added weight would prevent Phos from having that same level of speed though these legs are likely strong enough to be where Phos can stand and move despite having the heavy metal alloy attached to and entering into their body.

Gold/Platinum alloy arms: After losing their arms to the ice floes when helping Antarcticite with winter duties
