NBA superstar Giannis Antetokounmpo, dubbed the “Greek Freak,” has sued an artist for peddling a shirt with his nickname, which is a registered trademark.

The Milwaukee Bucks star claims a Philadelphia-based artist has placed the nickname on a T-shirt depicting Antetokounmpo with deer antlers — and is turning a profit on his name, according to a lawsuit filed in Manhattan federal court on Monday.

Antetokounmpo’s lawsuit states that “there is no question that the products sold by Defendant under the GREEK FREAK mark were sold by defendant with the purpose of confusing and misleading consumers.”

The suit continues that the artist, Jinder Bhogal, wanted consumers to believe that “they are purchasing products associated with or endorsed by Giannis Antetokounmpo, one of the most successful and popular NBA players.”

Antetokounmpo claims that he hit Bhogal with a cease-and-desist letter in May but that the artist never responded to the letter.

Bhogal did not immediately respond to a request for comment.
