Mary Jane Watson was instilled with morals from a young age by her father Craig, a lawyer who refuses to represent clients with questionable reputations. MJ has watched countless times as her father has turned down large sums of money to represent suspected murderers, drug dealers, and corporate criminals.

This approach has created some financial troubles for the family, and a strain on her parents marriage, causing Mary Jane to fear that they may eventually split up. Despite this, she maintains a positive outlook on life and is a genuine, friendly person who always wants to help whenever possible.

MJ's passion is her artwork, which she is quite talented at. Her father once pushed her to follow in his footsteps, but Mary's dream is to pursue her art as a career, doing what she loves to do.
