What is opposite of southpaw?

The opposite of a southpaw is sometimes referred to as a "regular" or "orthodox" fighter. This describes someone who stands with their left foot forward and their right foot back, with their right hand being the dominant hand. The term originated in baseball where a left-handed pitcher was also known as a southpaw due to the orientation of baseball fields. However, in fighting sports, the term southpaw has come to refer specifically to a left-handed fighter.
