Mr. Underwood

Mr. Underwood is Greg's Physical Education teacher. In the movie, he is renamed Coach Molane. He has a very little role in the book, but it's bigger in the film. So far, he has only made an appearance in Diary of a Wimpy Kid and The Last Straw. His role in The Last Straw, was a minor but important appearance, where he was walking with Mrs. Mancy to mark the student's dancing abilities, in regard as it counted to 20% of P.E. Grades. Not much is clearly known about him, but he does show gratitude to Greg.
