Masher 2.0 is a monster appearing in the episode of the same name that chased the demon hunter Knuckle Joe and is the upgraded form of Masher. Being an improvement of the original Masher (which was regarded by Nightmare as one of NME's most powerful creations), Masher 2.0 is almost invincible and is impervious to nearly every attack thrown at him. Masher 2.0 also has much more brute strength than the original machine, as well as the ability to shoot massive lasers from his chest. After Sword and Blade try to defeat him, Joe decides to take him on alone. But his efforts are simply no use, and is about to get severely injured (again). Just then, Kirby comes with his Warp Star and saves him. Becoming Fighter Kirby, Kirby buys Joe some time while Meta Knight gives him his fathers locket and explains that it can amplify his power. Joe harnesses the memento's power and, with the help of Kirby, causes Masher to explode and eliminates him for good.
Masher 2.0 is simply a larger version of the regular Masher, and has a red orb on his chest. He also has a small gold orb on his forehead and one on each of his shoes and has a more evil-looking red visor. Instead of a cape, Masher 2.0 has large metallic wings with solar panels on them, which he can use to take in energy for his laser beam attack. His flail is now larger than the original. The wings are also connected to a large jet pack which he can use to hover through the air.
