From the flamboyant evil sorcerer, Quan Chi, in Mortal Kombat: Conquest, to the sarcastic undercover agent in The Gristle, to the regal falcon-man in Hidalgo, Adoni has consistently proven his ability to play a diverse range of intriguing characters. This talented actor's ability to incorporate a number of different accents and dialects coupled with his exotic looks and athletic physique truly make him a joy to watch in other such blockbusters as: The Scorpion King, Troy, and Bad Company.

Being an exceptional all-around athlete in high school, it appeared Adoni would pursue a professional career in some sport. Turning down various athletic scholarships, he enrolled at West Virginia University and graduated magna cum laude with a Bachelor's Degree in Business Administration.

But, from years of being entertained by Adoni's impromptu comedic performances and impersonations which began when he was a small child, his father told him that the suit and tie of the business world would probably choke him to death and encouraged Adoni to give acting a shot. Surprised, yet intrigued at this suggestion, Adoni enrolled at Park Point College (now a University) in Pittsburgh, and studied acting, dialects, singing, and a bit of dance. Then, with the help of his younger brother Chris, he headed for Hollywood.

Born and raised in Burgettstown, Pennsylvania, a small town near Pittsburgh. he is the middle son of Petro and Despina Maropis and is very close to his brothers, Sam and Chris.
