Masher 2.0 (Kirby: Right Back at Ya! episode)

Masher 2.0 is the sixty-fifth episode of Kirby: Right Back at Ya!. Knuckle Joe returns for the third time, and this also marks the second appearance of his father and Masher, in the form of the similarly-named Masher 2.0.

Synopsis
Knuckle Joe returns once again, this time badly injured and therefore placed under the care of Tiff and Kirby. It soon turns out he's being chased by a new and improved form of Masher, called Masher 2.0, who was responsible for his injuries. Knuckle Joe sets off to battle Masher alone, but Joe still isn't even fazing him with his attacks. Meanwhile, however, Tuff, Fololo &amp; Falala keep an eye on King Dedede and Escargoon as they create a new invention that supposedly lets the King make his own monsters without having to pay Nightmare Enterprises a cent, and figure it might be a power amplifier to help Joe defeat Masher 2.0. Also, meanwhile, there seems to be a secret within the locket that Knuckle Joe's Father used to keep before Joe kept it for his father. Just what is the secret within the locket? And can it coupled with the invention really help Joe defeat Masher, this time once and for all?

Trivia

 * This is the most profane episode in the series, with Knuckle Joe saying "damn" and "bastard" several times, profanity which is appropriate for a Japanese children's show but inappropriate for a American children's show. There is also blood in one scene. All of which was removed from the dub.
 * In the Japanese version, King Dedede wants to sell Knuckle Joe's microchip to NME at a incredible price, while in the dub, Dedede wants to use the microchip to "make an army of monsters".
