How has Leonardo's leadership role evolved across different TMNT comic iterations?

In the original Mirage comics, Leonardo's leadership was often a heavy burden, marked by internal struggles and a more grim demeanor. Later iterations like IDW Publishing's TMNT series further explore his development, showing him grappling with doubt, spiritual challenges (e.g., being temporarily possessed by the Foot Clan's spirit, Kitsune), and learning to balance his strict discipline with understanding his brothers' individual needs. His evolution often involves learning to lead not just by strength, but by empathy and strategic thinking.
