Adil Akyuz is Arthur's 8-year-old Turkish pen-pal.
Arthur and Adil have a lot in common. Adil's best friend, Onder, is similar to Buster. They also both think that their sisters are annoying. Adil lives in an apartment and his room has a computer. His father owns a grocery store below his apartment, where Adil works on the weekends.
In "Is That Kosher?", it is revealed that Adil and his family celebrate Ramadan, which implies they are Muslims.
He probably plays soccer, because he has a soccer poster, has cleats under his bed, and has a soccer ball at the end of his bed.
Adil is a bear with a brown skin complexion. For casual clothes, he wears a green short-sleeved shirt with purple and white stripes, along with jeans. His school clothes are a dark blue collar shirt and tan-gray trousers.
