Leonardo
One of four brothers mutated from ordinary turtles by a mysterious ooze and raised in the sewers of New York City by the rat sensei Splinter, Leonardo was trained in the art of ninjutsu and became the disciplined, blue-masked leader of the Teenage Mutant Ninja Turtles.
Sharp-eyed fans of IDW's acclaimed TMNT universe will recognize Leonardo as one of the cornerstone figures of the publisher's Modern Age reinvention of the franchise, debuting in Teenage Mutant Ninja Turtles Micro-Series #1 back in 2012. Over more than a decade of storytelling, he's shared pages with his brothers Raphael, Donatello, and Michelangelo, as well as the venerable Splinter, weaving through some of IDW's most ambitious turtle tales. His presence across prestige collections like The IDW Collection and the emotionally charged The Last Ronin β Lost Years speaks to his enduring importance in this corner of comics. Whether you're a longtime shell-head or just diving into IDW's rich mythology, Leonardo is absolutely a character worth following.
