An alpha character is a person who possesses certain traits that often lead to a position of authority or one who is just born with the “alpha” personality.
Often times, this ranges from military generals commanding armies to the stereotypical “dare devil”. This means having control over others and not being at the mercy of others. It’s hard for an alpha to be walked all over by someone else because they will demand their place in society.
All the major players such as Tony Stark and Batman are also considered alpha characters because they live without fear, push past any limits imposed on them, have great self-confidence and have motivation. They also value honor above all else.
