First of all, we've got Cherro! (Might get a new name and surname later)

He used to be a prince, but [blah blah blah, castle gets attacked, parents die, gets separated from siblings, y'know, development].

His parents are actually human; the reason he is a dragon is because his parents got cursed to not have a single human child, and for a kingdom mostly composed by humans that's an actual threat to the throne. Him and his 2 brothers and 2 sisters are all different species, with him being the youngest child.

Personality wise, he's egocentric but also charismatic and kind. He is energetic, but will forget most things easily if not interested.He is very easily hot tempered, too. He enjoys listening to bard's tales and partaking in plays. Although coming from royal blood, he has a deep hatred for gods, kings and any cult-like association that controls people. He's also not very fond of humans. Cherro is Pan/Ace.

His most remarkable weapons are his scythe, wings and firebreathing.

As an adult, he becomes a bounty hunter. He also (Trigger warning: gore)

He cuts off both his dicks and sells them because he does not consider them useful.

Then, there's Azion!

He's a wolf protogen that comes from another dimension.

He was sent with a team of other protos to examinate a planet's resources, atmosphere and biology in order to let his superiors know if it was habitable. After investigating a cave, he found a cristal that led him to the world where he is now.

He was found by little prince Cherro during sword combat practice, and he demanded to keep him as a "royal companion". The king accepts this request and the children quickly become inseparable friends.

Azion has a database in his brain full of useful survival knowledge. This information also includes data about forging, biology, handling weapons, etc. Since his knowledge was already enough on those topics, he decided to study magic, and becomes a fierce wizard. Don't worry, he's already over his "robot studies and comprehends how humans live and work".

Overall, he's a loyal companion who never leaves Cherro's side. His hobby is to study terrains and geology, just as he was assigned to do initially. Azion is bi with a preference for women. Though he's used to the universe he's in, sometimes he wonders if that's the best that could've happened to him.

And last but not least (by now), Neth! (Need surname)

Neth is the son of a nobleman who got rich by collecting and selling various rare items. He inherates this, as he later becomes the owner of various stores that sell various goods. After the castle was attacked, Neth begged his father to let Cherro and Azion stay with them for some time, and after some arguing his parents allow it

Neth is a smart, slightly shy cat. He enjoys company, though he is not very energetic. Two of his passions are reading books and observing different animal species. He is fluent in various languages and can read and translate them. If necessary, he fights with a crossbow with really good aim.

He is Cherro's best friend apart from Azion, and they understand each other very well. Both accompany each other and are as comfortable doing so as when they are alone. His relationship with Azion is also quite joyful.
