Firebos

Phobos was a prince that had to escape his planet due too war (Meouch was his bodyguard).

His body is made out of a charcol/rock like substance and his innerbody/ hair is fire. His heart is a crystal cluster that is very fragile and exposed via a hole in his chest surrounded by a jelly/jello like substance (u can like stick ur hand in there bc its a very soft material and access the heart so he keeps it covered by his armor and clothing.

Oh also the heart smokes too but it travels up through the boy and out the head, but can seep out of the gel at time.

When he gets into a state of high emotion, like grief or starts to crystalize, and he becomes cold. He can detonated causing a massive explosion if too high of a state anger is triggered. His fire changes via emotions, when he is sad or greiving his flames die down alot and tons of smoke releases(they can escape out of the helmet).

If he's angry his flames grow very high and can start spitting out everywhere with out his helmet on.

He is extremely hot and as so he cannot touch the others (except for Havve cause robot). He has his specialize armor, suit and gloves so that he doesnt cause burns or damnge anything. His gloves are extra thick, but they are still extremely hot to touch, and the boys can only hold hands for a few seconds otherwise he will accidentally burn them.) The only exception is when he is in deep sorry and his flames are near extingushed he cools right down. But that is defiently an unsafe state for him to be in

His right eye can shift around due to being floating around and his antennies can bed up and down a lil bit.

He has his own speical reinforced bedroom in the ship. He sometimes gets nightmares (mostly about home) and because he cannot control his flames/body when he is asleep he has bursted flames/ exploded before. So he mostly sleep's alone. But sometimes Havve will sleep in there since its only safe for him, well kinda but he can help Phobos with his emotions when so. (Havve can feel pain but tends to ignore it if he gets burned or such.)
