Johnny Zest (né Landgraab) is a pre-made Sim who resides in Oasis Springs from The Sims 4. According to his family bio, he is a member of the Landgraab family but was disowned from dropping out of school to follow the career of being an Entertainer.
He has no relationships at the beginning of the game. His family does not remember him and do not recognize him as part of the family which could be believed to be from him being disowned.
Johnny lives on his own in Slipshod Mesquite, a trailer home and begins with §3,950.
- Johnny's lifestyle and background has some similarities to that of Dudley Landgraab. They both are disowned by family and live in trailer homes within a sand-covered region. The main difference is that Johnny is career ambitious, while Dudley is not.
- Due to a bug, Johnny's names would sometimes switch, causing him to be called "Zest Johnny", instead of Johnny Zest. However, this was fixed as a part of patch 10.
- He seems to be designed loosely after the titular character from the cartoon Johnny Test, in terms of outfit choice and chatty, playful personality.
