Reese is the second oldest of the children, and is also the least intelligent and most destructive, although at some times, he shows even more intelligence than Malcolm when devising fiendish plans. He even had a mean streak in the womb; while his mother Lois was in labor, he kicked her so hard that she forcefully gave 'pre-mature' birth to him. Immediately following his delivery he kicked the doctor in the nose. His obsession with violence horrifies the family and leaves him with few friends, partly as he is a bully at school. He bullies the "Krelboynes" in Malcolm's class, as well as his younger brothers, especially Dewey. Due to this, Reese is seen working out a lot to give himself a muscular build.
