Teenage Mutant Ninja Turtles — Movie Quotes

Michelangelo's catchphrase throughout all five seasons, typically yelled as he leaps into a fight. It became the incarnation's most quoted line and its clearest bit of branding.

The series' signature battle cry and its thesis in one nonsense word: these are teenagers first and ninjas second. Where other incarnations shout something triumphant, Mikey shouts something silly, and the show never apologises for it.

Used sparingly across the run alongside 'Booyakasha', usually at moments of pure surf-culture exuberance; the interplay between the two catchphrases is one of the ways the series negotiates between nostalgia and reinvention.

A deliberate nod to the franchise's own history — the 1980s catchphrase resurfacing in a 2012 show, signalling that this version knows exactly which shoulders it stands on.

From the fifth-season crossover 'Wanted: Bebop and Rocksteady', in which the 1987 Shredder and Krang recruit the 2012 Bebop and Rocksteady; the 1987 Raphael delivers the line to the far more lethal newer mutants.

A fourth-wall break that doubles as commentary on the whole franchise: the 1987 Turtles came from an era of consequence-free Saturday-morning adventure, while the 2012 series had by then killed characters and destroyed a planet. The joke lands because both statements are true of different shows.
