What is the name of this cartoon character?

My son chose to paint Dilbert on break with a coworker having mugs of coffee. He was in elementary school and the painting has a charming crudeness only a mother could love 💕

I have my son's painting from elementary school of Dilbert and s naly coworker having mugs of coffee. I learned the strip began the year my son was born

I am an engineer, so a favorite part of the cartoon was when Dilbert's mother asked the doctor if he would be normal. The doctor replied, "I'm sorry, no. He'll be an engineer."
