Aster X / IronLight. Metal Souls

The Iron Light Core is the heart of every Metal Soul Bot. It gives the bots life, and it stores everything—the bot's soul, its energy, and the magic it uses for attacks.
The Iron Light's core is a glowing blue sphere with a small white star inside.
The Iron Light Core inside Metal Soul Bot is not visible, but if one were to look through it, one would see that the core is located in the bot's abdomen, with blue vessels running from it throughout its body.
If you pull the core out of Metal Soul Bot, he will still live, but if you break it, he will instantly and irrevocably die.
Likewise, if you place Iron Light's core in any iron "vessel," it can immediately begin to form Metal Soul's flesh within it. This doesn't necessarily have to be a robot. Even if you place the core in an iron cube, it will "grow roots" there as well.

Metal Soul Bots are living creatures made of metal on the outside and flesh and blood on the inside, identical to human flesh, except their insides and blood are black.
The 4 main and currently only active Metal Soul Bots were assembled from simple metal by humans, and their insides were formed from the core of Iron Light.
Metal Soul Bots can attack opponents by storing magical energy in a specific part of their body and releasing it in a powerful discharge upon impact.
Metal Soul Bots feed on machine oil. And those with mouths can chew on iron to strengthen their armor.
The Metal Soul Bots' iron armor is like their skin.
Metal Soul Bots live slightly longer than humans: almost always 100 years.
Metal Souls feel everything that humans do. They aren't programmed, they have souls, so they're very similar to humans.

Numerous Metal Soul Bots arrived on Earth, stripped of their bodies and left in the form of Iron Light cores. They arrived on the planet from another universe, a gateway to which was created by a powerful explosion that triggered "dimensional breaches."
The explosion was caused by the clash of two very powerful Metal Soul Bots: Moonlion and Nideenloid.
Nideenloid arrived in the Metal Soul Bots' universe from another galaxy, and Moonlion tried to force him to return to avoid causing a cosmic collapse. But he failed.
Metal Soul Bots, who find themselves on Earth, do not remember their past or even their former names and live anew, trying to establish contacts with people.

Aster is a determined, disciplined, yet gentle and good Metal Soul Bot.
Appearance: Aster X stands approximately 398 cm tall. He has a strong build, with massive, powerful legs and dexterous hands. His primary colors are red, yellow, and pink. His arms, legs, chest, and head are red, while his palms, joints, torso, and eye shield are black. His chest, legs, and arms have yellow accents, and his eyes are pink. Unlike the Chloride Bots, Aster and Dox have mouths. Aster's mouth is made of red parts: two jaw halves connected at the sides by elastic red rubber to allow free pronunciation, and his teeth are made of yellow metal and specially sharpened. He is designed in an Egyptian style: he has a pink cape on his shoulders, black horns, and a pink crescent moon on his forehead. He also has a decorative element: wings on his head just below the horns.
Aster X's personality is that of a typical older brother. He's brave and disciplined, but deeply vulnerable. Aster sometimes looks after Dox (another metal Soul member of his crew) like a younger brother, even though they're not. If Aster X gets angry, he might hurl insults, but not too harshly. And if you start a fight with him, he'll defend you. Aster X's defining characteristic is that he takes great interest in watching people celebrate major city holidays, like New Year's, City Day, and so on.
He and Dox have a brotherly, friendly relationship: Dox constantly teases Aster, but Aster tolerates him. Aster X is very concerned for his friends, although he doesn't show it through overprotectiveness.
Aster perceives Daxt and Ivy (his creators/people) as his friends and mentors in the human world.
Also: Aster X, in a critical moment, is capable of unleashing a powerful energy wave that can knock anyone unconscious and temporarily disable them. But he himself doesn't know this yet.
