Super Mario Legacy: Super Mario Bros. 4

 is the sequel to Nintendo's Super Mario World: Super Mario Bros. 3 for the Super Atari-Nintendo Video Advanced System.

Story
Intro: It was a peaceful day in the Mushroom Kingdom. Mario and Luigi are simply relaxing outside their house. It was 2 weeks after their vacation with Peach, Daisy, and Pauline in Dinosaur Land. Suddenly, A loud boom is heard and they see the Mushroom Kingdom in flames with new high-tech airships. The bros. immediately rush to the scene. Upon reaching the castle, both Peach and Daisy as well as the Councils of 8 for each kingdom (Mushroom Kingdom and Sarsaland) were taken prisoner by a masked man named Prince Havoc, new ruler of the Flower Kingdom, along with the magical Princess Onyx and the fierce Napoleon Knight. The prince challenged the brothers to go after him before they flew to the other side of the kingdom. At this, 2 Toads named Buckenberry and Ala-Gold who were members of the Councils (Buckenberry is of the Mushroom Kingdom while Ala-Gold is of Sarsaland) joined them willingly to save their friends and the princesses.

The Rest Of The Story: Throughout the journey, the quartet fight off clones of people they recognize. These clones are made of a strange metal that can come alive. At the middle of the path, they get ambushed by Princess Onyx and Napoleon Knight, but the heroes won. Further on, they eventually reach Dark Flower Kingdom, where they encounter Nap. Knight and Princess Onyx again, but this time, the duo reveals their ability to become metal and despite that ability, they lose to Mario, Luigi, and the Toads. Our heroes fight Prince Havoc, who has the ability to become metal too and even uses a mech against them. After the mech, his mask shatters and falls off, revealing to be Prince Haru all this time. He then coats himself with dark magic and fights the quartet again, but he gets defeated. Mario, Luigi, Ala-Gold, and Buckenberry succeeded in their mission to rescue Peach, Daisy, and the Council members.

Bosses
Hit points: 1 stomp = 3 fireballs = 1 hammer = 1 Grab Block = 1 ice block = 3 lasers
 * Super Onya (Boss of Peach's castle): As Mario, Luigi, and the Toads reach Prince Havoc, he sends down the large Onya. Unlike regular ones, this one walks and jumps. Sometimes, it jumps and tries to crush the player with its shell. If it misses, it gets stuck on the ground, letting its belly get stomped. Stomp it thrice and the Super Onya is defeated.
 * Boom-Boom Copy (Recurring miniboss of Worlds 1, 3, 5, and 7): This clone created by the prince acts the same as the real deal. World 1 has him red, World 3 has him yellow, World 5 has him green, and World 7 has him blue
 * Pom-Pom (Originally from SM3DW, only the World 2 one is real, the rest are fakes) (Recurring miniboss of Worlds 2, 4, 6, and 8): Boom-Boom's sister. She was tricked by the fake version of her brother and after the World 1 battle, she realizes the ruse she was brought into, which reaches the word of Prince Havoc, who begins to clone her. Both the real one and her clones have the ability to make fakes and throw real shurikens. Only the real one throws a pink shuriken while the fakes throw blue ones. 3 stomps take the boss down. In World 4, the clone is colored lavender, World 6 has her purple, and World 8 has her violet.
 * Link Clone (Fortress Boss of World 1): A superclone created by the prince, this one was meant to be used against Hyrule. It can shoot sword beams and throw bombs just like the real Link, but 5 stomps take it down.
 * Airship Bomber (Boss of World 1): A prototype weapon piloted by a Rocky Wrench, it drops down Bob-ombs, but throwing about 8 of them back defeats it.
 * Kirby Clone (Fortress Boss of World 2): A superclone created by the prince, this one was meant to be used to conquer Dreamland. Just like the real Kirby, it can inhale as well and do slide kicks, but 5 stomps take it down.
 * Mad Pokester (Boss of World 2): An ordinary Pokey that was cursed by a strange Magikoopa due to a shady deal since he was bullied due to being an immigrant from a desert. He shoots sharp rocks and causes upward sandstorms to make the player float up to the head. His weakness is any regular rock thrown at him, but his head is the only vulnerable segment and is high.
 * Samus Clone (Fortress Boss of World 3): A superclone created by the prince, this one was meant for plundering treasures from dangerous and protected kingdoms. Just like the real Samus, it can shoot electric balls and rockets, but 5 stomps take it down.
 * Enemy Spawnertron (Boss of World 3): A prototype machine that makes biological clones of enemies. Hitting the cockpit (where Prince Havoc is) 10 times causes it to blow up, but not before the prince gets away via the cockpit revealing itself to be a smaller Clown Car-type vehicle.
 * Bomb Piranha (Fortress Boss of World 4): A Piranha Plant enhanced to shoot bombs instead of fire. It is also fireproof to prevent itself from blowing up. 7 bombs are needed to take it down.
 * King Bob-omb Sr. (Boss of World 4): Lord of the Bob-ombs, who holds hatred for humans. He sends down explosive Bullet Bills that lock on the player, but also explode when they hit him. He is defeated when hit thrice.
 * Napoleon Knight and Princess Onyx (Midway Boss between Worlds 4 and 5): Prince Havoc's cohorts. They kidnapped Mario, but Luigi saved him and stopped their diabolical scheme. 2 days afterwards, they joined the prince out of vengeance and promise of power. Their attack patterns are the same as in Luigi's Adventure: Mario is Missing!, but toned down and both fight the player one at a time with swapping out, with occasional duo attacks. Both require 5 hits each.
 * Ninji Master (Fortress Boss of World 5): The Ninji who trained Pom-Pom. Prince Havoc tricked him into thinking that Mario, Luigi, and the Toads are evil. His attack pattern is the same as Pom-Pom's, but all the shruikens are gray along with him and the fakes doing ninja kicks if the real one is not stomped. However, the real one has his shruikens move slightly faster. Upon defeat, the heroes explain the truth and he apologizes for breaking his moral code where he must not attack innocent people.
 * Mechakoopa Model X (Boss of World 5): A remodeled version of Tyrano's Proto-Koopa. Aside from rockets, it now has a flight system and is stomp-proof, but is vulnerable to 5 shells.
 * Spawnertron 2.0 (Fortress Boss of World 6): An upgraded version of the Spawnertron which can make metal clones and also mecha enemies. Its weakness and health is the same.
 * Stolen War Robot (Boss of World 6): Before the heroes can get to Peach, Daisy, and the Council members, Prince Havoc sends down the robot which is a prototype of a weaponized Talos 2.0. The attack pattern is identical to the original Talos, but there are now Bullet Bills and Bob-ombs thrown in.
 * Airship Bomber + Tank (Fortress Boss of World 7): Piloted by the same Rocky Wrench from before, it starts out in tank form where it shoots cannonballs and floor fire. After taking 3 hits, it changes back into bomber form where it is identical to the original fight, but there are 2 spike balls that revolve around it to destroy thrown Bob-ombs. That phase takes 5 hits.
 * Magikamek/Kamek's brother (Boss of World 7): The twin brother of Bowser's personal wizard. The difference is that his hood is red with his glasses being cracked. He attacks by firing magic, teleporting, and transforming enemies. While strong in magic, Magikamek's stamina is weak and takes 3 stomps.
 * Metal Masters Napoleon Knight and Princess Onyx (Fortress Boss of World 8): Back for revenge, the duo fights the same way, but this time, their attacks are slightly faster and their duo attacks occur more often.
 * Metal Master Havoc (First Boss of World 8): The mastermind of the Flower Kingdom. He had the Mushroom Kingdom and Sarsaland invaded to lead the heroes to a trap so he can take them out before claiming the princesses as his own. His attack pattern is a combo of Prince Haru's attack patterns from SMB2: TLoWZ, where 3 stomps make him change to the next pattern. After all 3 patterns, he moves on to the next phase.
 * Mecha Flowertron (Second Boss of World 8): A huge flower-shaped robot that's patrolled by Havoc. Only the head is the weak spot, and the way to get up there is using the moving platforms. It fires rockets and bombs to keep Mario and co. away. After 2 stomps to the head, it destroys the floor and it fires homing missiles and even lasers. Another 2 stomps cause it to blow up, which leads to Havoc landing on the platform the player is not standing on and the reveal that he's Haru.
 * Dark Magic Prince Haru (Third and Final Boss of World 8): The prince and mastermind of the Flower Kingdom now endowed with dark magic. His attack patterns are similar to Marx's attacks from Kirby Super Star, but a few liberties are thrown in, such as summoning phantoms of the hero clones to execute certain attacks. This battle takes 10 hits to beat, but he is immune to fireballs and ice cubes. When 5 hits are left, he begins to attack and summon a clone at the same time, but 5 more hits and he's defeated.
