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 & 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?
Full episode summary
Spoiler alert: The following section contains plot-specific details.(Skip Section)
The episode starts in a part of the galaxy as it zooms in on a red planet, which appears to be heavily desecrated. As it soon zooms closer to the planet, it then shows Knuckle Joe in a battle against an army of Nightmare's monsters led by Masher 2.0. Not faring too well against Masher, Knuckle Joe is sent flying against a wall and making a hole in it. Masher hurls his flail at Knuckle Joe, which he jumps out of the way to dodge. Several Monster Soldiers make their way towards Joe, yet Joe manages to clobber and destroy them all. However, Masher is left unscathed by Joe's attacks, and Knuckle Joe soon realizes that he's becoming too injured to fight the metal monster now, and decides to make a break for it. He slowly and weakly makes his way to the room where his Monster Transmitter is, and Masher follows, hoping to catch up with him. A panting Joe manages to make it to his Monster Transmitter and prepares to use it to escape to King Dedede's Castle.
As they are patrolling the hallways, Sword and Blade find Knuckle Joe lying on the floor and take him to Tiff for some rest. He awakes and sees Tiff and Kirby again. He is pleased to meet his friends after so long, but he realizes his pendant is missing, and freaks. Meta Knight and Tuff are scoping the throne room, when Tuff finds Knuckle Joe's pendant, but shortly after, Escargoon takes it and goes with Dedede to examine a microchip inside of it while Tuff takes the pendant. Meanwhile Knuckle Joe tells Tiff and Kirby of a revived Masher, and that he needs his pendant because there's something special about it, so he and Kirby run off. Meta Knight and Tiff also go with them.
Dedede and Escargoon find out that the microchip holds tremendous power, so they decided to use it to make an army of monsters, but Tuff, Lololo and Lalala are spying on them. Sword and Blade run into Masher and failed to hurt it. Joe appears and attempts to defeat it. He tries aiming for the eyes, and he succeeded. However, this did not affect Masher. Kirby gets Tiff to call for the Warpstar to save Joe. He made it, but Kirby crashes toward a rock pillar, while Joe says that Kirby may be a great Star Warrior, but he makes a lousy driver.
Back at the castle, Escargoon finishes building a bracelet for the microchip,but it still needs a jewel to work it, so Dedede uses Escargoon's hidden box of jewels, but Lololo and Lalala take it from them along with the bracelet. Tuff, Meta Knight, Lololo and Lalala escape and give Joe the bracelet, while Meta Knight tells Kirby to transform, so Joe throws a Smash Punch in Kirby's mouth, and he transforms into Fighter Kirby. He distracts Masher while Joe tries out the jewels.
Masher, however, open up its wings and shoot a large beam at Joe and the others. The Jewels were lost in the blast, but Tuff gave Joe the pendant that his father gave him. Both Masher and Joe face each other, and prepare to launch a powerful attack. Masher charges its wings while Joe readies his fist, both launch a beam, but Masher's prove to be too much to Joe, so he tumbles and almost gets blasted by Masher's beam, but Kirby flies just in time to assist Joe. While both beams clash, one of Masher's wings disintegrate, canceling out its beam, and leaving it open for attack. He is blasted by the other beam, then starts to malfunction, then after, explodes. Joe's pendant dissolves, but does not care and thanks everyone for helping him take out Masher. Everyone rejoices at Masher's defeat.

Changes in the dub
In the Japanese version, King Dedede wants to sell Knuckle Joe's microchip to N.M.E. at an incredibly high price, while in the dub, Dedede wants to use the microchip to "make an army of monsters".
Kirby says Joe's name in the Japanese version when entering the room he's in, but instead says only "poyo" in the dub.

In this episode, it's very unusual that a monster returned for revenge, and even stronger than before.
