=== Bowser's Mario Clone Scheme (Early 2004) ===
After posting about an upcoming "secret" weapon online, Bowser finishes working on his newest creation: four Mario clones. He gathers them all at Eternal Star, where he briefs them on their primary objective of destroying Mario, by any means necessary.
The quartet make their way to the Mushroom Castle's entrance, and Mario greets them at the door. He asks if they're his fan club, to which they respond by explaining their origin and purpose. Mario blows them off, but the clones give him no mercy and attack Mario relentlessly. Mario runs away screaming, so the clones pursue him to Bob-Omb Battlefield. There, they once again explain their directive, and Mario continues to run in fear. They stop him at every turn, and he is forced to abandon the castle to escape their watchful gaze. The four then guard the entrance to the castle, hoping Mario will eventually return and meet his doom. 
Following an encounter with "chocolate fairies", the clones once again sight Mario, now attempting to sneak past them using a costume of his own oversized head. Mario makes it inside, only to be met by the clones (who claim they used magic to get here before him). They then beat him to a pulp.
Following their attack on Mario using a chainsaw, the clones congregate outside to establish a new plan of action. The leader suggests they split up to check various parts of the castle, in order to weed the plumber out. The others begrudgingly begin their search, with the leader eventually reaching his hiding place in Bob-Omb Battlefield. He asks the Bob-Omb Buddies if they've seen him, but they stay silent. Mario jumps out from behind a cliff and signals everything in the battlefield to use a cheat code, allowing all objects and people to swarm the clone. This torrent of battery enrages the clone and makes its eyes glow red, revealing itself to be a robot all along. It manages to disable the cheat and calls its comrades for assistance. Mario runs away, but uses the knowledge that they're merely robots to his advantage. He defeats them one-by-one via disconnecting their parts, overloading their memory circuits, etc.
The final clone meets Mario at the battlefield's summit. It proceeds to attack with bullets and punches, but is dealt a heavy blow when Mario throws an exploding King Bob-Omb onto it. Now heavily damaged, the clone goes into full destructive mode and unleashes a barrage of missiles at the plumber. However, its damaged circuits cause its aim to be impaired, and it accidentally blows itself up, suffering irreparable damage. Mario watches as the robot's sight begins to dim and it deactivates for good.SMG4: "4 Clones 1 Italian"
=== Luigi's Payback (Early 2004) ===
One day, an alliance is formed between Bowser and Luigi, due to the latter's growing resentment toward his brother. After many attempts on Mario's life, Bowser becomes desperate, and brings out a new batch of seven clones—nearly twice as many as before. Mario greets them at the front door of Peach's castle, once again asking if they're his fan club. After some brief confusion on who their target is, the clones begin their assault on their mustachioed prey. Mario eventually manages to shake off the clones, and they're never able to find him again (an obvious downgrade to the tracking skills of the previous four).SMG4: "Luigi's Payback"
