Alexander Lightwood

Alec is brave, caring, and compassionate. He is blunt and straightforward as he never grew accustomed to pretenses.

Alec was initially uncomfortable, self-conscious, and serious in most situations; in this sense, Alec was very much the opposite of his sister. He was rarely proud, believing himself without many accomplishments, though he'd always hoped to make his parents proud of him. When he turned eighteen, Alec took pride in being allowed to attend Council meetings with the other adult Nephilim.

Partly due to his upbringing and the beliefs he was taught in his youth, Alec was judgmental, arrogant and condescending at times, and initially held prejudice towards Downworlders, though this eventually changed when his life became so intertwined with many of them. He was also initially unwelcoming of strangers and people he deemed a threat to his family. Alec is also sarcastic, with a dry, biting sense of humor, particularly in remarks directed at people he doesn't feel particularly keen of. He would make no effort to hide his ill feelings towards them, showing it in small subtle ways like openly ignoring them or not heeding their opinions.

Alec was also once scared of admitting, even to himself, his own sexuality and feelings, even more so because he was concerned about his parents' and other people's opinions. For a long time, Alec chose to avoid potentially getting into any form of relationship by letting himself believe that he was hopelessly in love with Jace, whom he is not allowed to fall in love with, because it would have been easier than facing the consequences of embracing his sexuality.

He can also be quite insecure and jealous, when it came to his own achievements as well as Magnus's romantic history. His insecurities along with the pressure he'd placed on himself made him somewhat guarded, though eventually, he overcame his own insecurities and became more confident in himself, with the help and assurance of those around him over the course of their adventures.
