Matthew Geczy

Matthew Geczy (born August 23, 1964, Georgia, USA), also written as Matthew Géczy, with an accent mark, is a Georgian-American voice actor working in Paris who provided some of the voices for the English version of Code Lyoko in the first 4 seasons. He has been living in Paris, France since the age of 18. His last name is pronounced as Gate-Sea. He informally goes as Matt. He is 5' 11¾" (1.82 m) tall. He periodically directs as well.

Raised on several US Army Bases, Matthew was offered a scholarship at New York University, but decided to decline it for a year with the intention of backpacking around Europe - he got as far as Paris, where he fell in love with the city and decided to stay.

He replaced Christophe Callabero as the voice actor for Odd permanently after Log Book.


His father, George Geczy II, is a retired US Army Colonel, George Geczy III. His brother, George Geczy III, is a Lieutenant Colonel who served as a battalion commander in the war in Iraq. Like Odd's mother, his mother, Evangeline Géczy, is an abstract painter, as is his brother's wife, Evangeline Geczy. Like Odd, he is the youngest of 5 siblings: Mary Jo, George, Michael, Andrew, and Matthew.


  • His father was born in Hungary.
  • It is revealed in Lyoko: Decoded that his favorite episode is Killer Music because of Odd's "pop rock revolution" line with Odd's CD player, and the fact that after he gets "frozen" everyone is worried about him for the whole episode. In that interview, he mock-complained about the length of the interview in Nicolas Poliakoff's voice.
  • He later worked with Thomas Astruc, directing "Miraculous Ladybug".
