Richard Parker is the son of Peter Parker and Mary Jane Watson. He's a teenage boy who happens to be quite reserved (for his age, anyways), and is always observing his surroundings, much like his mother. He also has a strong affinity for reading, much like his father, but can also be quite the skeptic. He's a lil blunt, but not to the point that he'll hurt others feelings, and gets his dry humor from both of his parents. 

Richard, like May, also has very few lines, but they are more evenly dispersed throughout the issues so depending on your audition, I may use your audition for this project. I'd also say anyone who can do a male pre-teen to early teen voice would be preferably for this role.
