He can be quite proud of himself, he can be polite if he doesn't want to get in trouble, but he always goes with a face of deep hatred, which sometimes is for that reason or just because he is always tired. He previously tried to draw attention to anyone who invaded his territory, but now he lives in constant misery of an abandoned factory.
Aggressive and instinctive when he feels in danger, he will not hesitate to attack you if he takes you as a threat, if you do not show signs of aggressiveness, he will settle for saying some hateful and annoying words so that whoever has interrupted his tranquility, leaves .
He is quite suspicious, although if you talk to him calmly he could put you aside while you talk or ask him, one wrong step and he will show his teeth.

-In order not to make it too long, Metaldor, from before he was born, never saw his parents. It was a stolen egg, in quite the wrong hands, thinking that this dragon would be of great use to the factory that two people were managing. They had taken a long journey upon hearing of these dragons with the ability to expel oil from their mouths. he would start up all the machinery that he required from the said element.
Also, that was not enough, when he grew up it was seen that the dragon was strangely social, so they usually left him at ease, he would always return home. He also learned to expel magma from his mouth, which they took into account for expanding the factory and forming a smithy. But everything was not going to last forever. At 24 years of Metaldor, they began to retain him more and more in the factory, first because of the "aid" that he generated for the company, but then his own "creators" began to call him as if it were an object and key piece, and He didn't like that very much.
One of those times, they had to anesthetize him for a fit of rage at being used. He was chained and a sorcerer was called so that he could not escape or break said chains, he would only remain at their orders. 2 long years were enough to throw him off balance.
Metaldor had fainted one of the times, due to the maximum performance that he generated and the little maintenance they gave him when feeding him. Then both administrators made a very strong mistake ... They stopped enchanting the chains when he remained in a state of deep lethargy.
And when he woke up, he trashed the factory as soon as he could. Although, after all, he considered it his home.
The two humans fled successfully, and Metaldor vowed to exact revenge on his creators.
Either way.
