Peps are enemies in Mario & Luigi: Bowser´s Inside Story that are found inside Bowser´s body in the Energy Hold area. There are three different types of Pep, the POW Pep, the SPEED Pep, and the DEF Pep, all of which specialize in a different stat. They can change themselves into a different type of Pep. They can also merge with other enemies to make them stronger in their respective stat, which is similiar to Ghoul Guys from the first game in the Mario & Luigi-series, Superstar Saga.
Types of Pep
POW Peps are red in colour and and have muscular arms. It attacks by getting close to one of the bros. and attempting to punch them, but they can counter by hitting the POW Pep when it is not covering it´s face with it´s hands.
The DEF Pep is green in colour and have a shield next to them. They cannot attack at all, so they are pratcically useless enemies despise their high defense.
SPEED Peps are blue in colour and have shark-like fins. They attack by charging at one of the bros. at a high speed. Sometimes it will split into two and charge at both of the bros..
