Naruto's sprawling anime output from its original series through Naruto: Shippuden have always been known to have enormous portions of filler breaking up its stories. While this provided occasional welcome interludes between major arcs, Naruto: Shippuden's particularly egregious moments came with filler arcs cropping up between pivotal moments of the Fourth Great Ninja War. While this was the inevitable byproduct of a weekly anime needing to break away from demanding canon content while continuing to entertain the masses, one such wasteful Naruto: Shippuden arc was that of Mecha-Naruto.
