Leonardo (TMNT, 2003 and 2018)

Leonardo in the 2003 TV series is more like Leonardo from the Mirage comics than the 1987 TV series and first three films. He is more well-balanced and serious than in the 1987 TV series and first three films. Like the Mirage comics and the film penology, Leo and Raphael have disagreements constantly, particularly in the City at War trilogy.
