Mikey seems to respect Leonardo and although there are few scenes with them interacting together in the first two seasons, it's clear that Leonardo cares about his youngest brother. In season three, however, the two of them go on missions together. While looking for Karai one evening, they worked together to rescue their brothers, April, and Casey from Bebop and Rocksteady. After Karai is captured by Shredder, Leo volunteers to go solo to find a way to help her, Mikey tags alongside him and assures he is there for him. When Mikey gets eaten by the MegaShredder, Leo fights with all of his might to save him. After Mikey escapes from inside the monster, Leo is overjoyed to see him alive and is proud of the work they have done. Raphael is normally seen as the one Mikey loves to hang out with, usually to Raph's ire. Although Raph repeatedly gives Mikey a beat down for his antics (usually in the form of slapping him to make him shut up) he occasionally shows a more sensitive side when Mikey is feeling down. Particularly at the end of season 2 and the first half of season 3, Raphael is much kinder to Michelangelo and often refers to him affectionately as "little brother". He is also less inclined to slap Mikey, instead flicking him with a finger as a sort of "warning". Of all his brothers, Mikey seems to be the closest to Donatello. This probably stems from the fact that although they are very different they both share a curiosity about things outside ninjutsu. Mikey greatly admires Donnie's new gadgets and is normally the first to test them out. Mikey additionally enjoys creating names for all the mutated forms of villains in the series, naming ones like "Dogpound" and "Fishface". He even is upset with Donnie when he decides a name (Newtralizer) before Mikey gets the chance, and Donatello yells at Mikey when he attempts to name the mutated Kirby O'Neil "Wingnut" - "You are NOT giving Mr. O'Neil a MONSTER NAME!"
