Pep

Peps are a type of enemy from Mario & Luigi: Bowser's Inside Story. The three types of Pep are found in the Energy Hold in Bowser's body.

The Peps have two special abilities, to form with other enemies to make them stronger in speed, power, or defense, and that they can change themselves into a different type of Pep, similar to the viruses from Mario & Luigi: Superstar Saga and the Ghoul Guys from Mario & Luigi: Partners in Time.

POW Peps
POW Peps are red with big muscular arms. POW Peps attack by getting close to Mario or Luigi and attempting to punch them, but Mario or Luigi can counter attack by using the Hammer at the correct time. If this enemy is fused with another enemy, the other enemy increases power.

DEF Peps
DEF Peps are green with a shield next to them. DEF Peps do not attack at all, making it easy to defeat, despite the defense. If this enemy is fused with another, the other enemy will gain higher defense.

SPEED Peps
SPEED Peps are blue with shark like fins. These Peps attack by bolting towards Mario and Luigi. The brothers can counter attack by jumping on them or staying still, depending on which area they are attacking. If this enemy fuses itself to another enemy, it will increase the other enemies speed.
