Dr. Richards is Peter Parker's new teacher after Dr. Connors turns into the Lizard and is subsequently retired. He plays a small recurring role during many of the school scenes that we have. Fair warning, if you do get assigned this role, Dr. Richards is actually a massively important role down the line, and while recasting is an option, it should be assumed if you are willing to play Dr. Richards and his less than elastic style of teaching you are in for the long haul.
