He has shown innocent empathy for others as shown in particular by his adoption of Klunk the stray kitten, to whom he is very close and also by his relationship with Leatherhead. It is his initial awareness of Leatherhead's humanity which ends up forging the bond between the crocodile and the other Turtles. He enjoys Leatherhead's company, although he can tease him on occasion against his better judgment. However, he cares greatly for the crocodile and is quick and willing to forgive and reassure him when a rampaging Leatherhead injures him in a blind, nightmarish rage in the episode 'Hunted.' Leatherhead also appears to care greatly for Michelangelo and is distraught when he believes he has fatally injured him, but delighted to discover that his fears are unfounded when he finds out that the turtle is alive and well.
