I like the one scene during Lion-O's anointment trials where his cornered by Slithe on top the mountians. Tygra knows he's not allowed to interfere but does so anyway and saves Lion-O's life.
Snarf going all badass to save some random Unicorn in the episode "The Terror of Hammerhand". Also counts as a Moment of Awesome for Snarf.
Both times that Lion-O was reunited with his father count in my opinion.
