He was able to sneak up behind Leo, wrap his arms around him and cover his mouth to silence him. WITHOUT MAKING A SOUND.
Leo had no idea that he was following him, he had no idea of Mikey’s presence on the rooftop. And he wasn’t aware that his little brother was right behind him at all the entire time.
That takes skill to catch LEO of all people off guard when he’s in full on mystic mode.
If Leo was an enemy and Mikey was trained to kill his targets: Leo would be dead.
Splinter has said that Mikey possessed the most raw talent of his brothers combined. Meaning he has the most potential to go above and beyond if he only focused and polished his abilities as a Ninja as much as his other hobbies.
The purest cinnamon roll of the group, the one who brings sunshine when his family is surrounded in shadows: has the most potential to become a assassin level ninja if he focused his time and energy on his training.
Really think about that.
