Episode Description:
The Name: When Gumball discovers his real name is Zach, he starts developing an evil alter-ego who takes over him and his memories. Darwin and his family must save Gumball and his memory by changing it back to his legal name "Gumball" before Zach takes over completely and Gumball will fade away.
