Early life

Young Cassidy Williams

Cassidy had entered the Darrow Mansion, along with the rest of her gang, but soon left after seeing all the traps that had been laid by Danny Darrow.

Scooby-Doo! Mystery Incorporated

Season one

Because Angel gave away that she knew about events in Crystal Cove twenty years ago that Destroido Corp. covered up completely from the newspapers, and because she produced the diary of Cassidy Williams, Velma accused Angel of secretly being Cassidy Williams herself. Angel admitted this to Velma, but asked that she say nothing until Angel revealed it to the gang herself.

She finally admitted her identity to all of them after helping them fight the Obliteratrix. She also told them how the old Mystery Inc. was forced out of town by threats to them and their loved ones, after they investigated an old Spanish church and found a picture of the Planispheric Disk. She warned them to stop their investigations or the same thing would happen to them, because the Freak of Crystal Cove that threatened them was "still out there."

Apparently it was Mr. E who had brought Cassidy back to Crystal Cove. (Pawn Of Shadows)

Season two

She stopped working with Mr. E, took back her real name, and got a shorter haircut.

She tried to convince Brad Chiles and Judy Reeves to care more about their son and less about the treasure, but she was rebuffed with threats.

Her radio warnings convinced Professor Pericles that she had to be dealt with.

The gang still didn't trust her, until she went with them on an underwater mission against killer robots and ended up sacrificing her life for them.
