- Good Luck Jessie: NYC Christmas (First appearance)
Luke is a mischievous, sarcastic, cool, and a prank-loving boy. Several times he is shown to be dull, especially in math, yet he is clever when it comes to playing tricks on his siblings and Bertram. Luke is nice and caring. Luke is a good kid, sometimes he pays attention and sometimes he is a little bit self-centered, especially when it comes to impress girls. He is shown to be intelligent, in Identity Thieves, but it was because he never tried, that he did poorly in school.
