Luigi’s Adventure: Mario is Missing!

 is a Super Mario game starring Luigi released in 1992 for the Super Atari-Nintendo Video Advanced System.

Story
Intro: A week after the vacation at Dinosaur Land, Mario is captured by the raging Napoleon Knight and the devious Princess Onyx! Only Luigi can save his older brother from their clutches.

The Rest of the Story: Luigi went on a long journey and battled an old rival, a traitorous Yoshi, a shapeshifting creature, and even the masterminds.

Bosses
Damage values: 1 stomp = 1 hammer = 1 Grab Block = 5 fireballs = 3 lightning bolts = 1 charged lightning bolt
 * Napoleon Knight (Recurring Boss of Worlds 1, 3, 5, and 7): The hot-tempered knight of the Hot-Cold Kingdom, he specializes in wielding a battle axe. His attack strategy involves attempting to ram into Luigi while swinging his weapon. Sometimes, he jumps and whirls the axe around himself to protect himself. However, 5 stomps take him down. With each encounter, he gets faster. By World 5, he throws mini axes like Hammer Bros. enemies and at World 7, he uses 2 axes.
 * Princess Onyx (Recurring Boss of Worlds 2, 4, 6, and 7): The devious princess of the Hot-Cold Kingdom, she specializes in dark magic. Her attack strategy involves teleporting and firing blasts towards Luigi. 5 stomps take her down, but with each encounter, her intellect lets her change strategies from using spread shots in World 3, using homing shots in World 5, and summoning a clone Luigi in World 7.
 * Foreman Spike (Boss of World 1): Mario's old rival. He was hired to destroy a part of the land to build a base under orders from an anonymous client. He attacks by riding an excavator which throws bricks. Occasionally, the machine throws a blue brick, which can be thrown back at him. The foreman must be hit 3 times.
 * Flame Serpent (Boss of World 2): A skeletal snake that's alight on fire. The monster never finds satisfaction in the current heat. It launches triple shots and burning rocks. Sometimes, it spits out a regular rock, which can be thrown back at it 3 times. However, the head is the only weak spot.
 * Powerful Porcupuffer (Boss of World 3): A raging Porcupuffer related to Big Bertha. This giant fish seeks vengeance on the one that took his sister down. He fights the same way as Big Bertha did, but occasionally, he spits out bubbles that can trap Luigi inside.
 * The false Mario (Boss of World 4): A faker created by the masterminds. This copy jumps and shoots fireballs. Each time he's stomped, he runs with Starman-like invincibility for 10 seconds. It takes 5 stomps to defeat him.
 * Sumo Warrior (Boss of World 5): The strongest Sumo Bro. brought under control by the masterminds. He sends lightning down each time he pounds the ground with his foot. Defeat him by throwing blocks that fall when he stomps the ground 5 times.
 * Traitor of the Yoshi clan (Boss of World 6): A Yoshi that openly chose to side with Tyrano and joined the masterminds for vengeance against the ones that defeated him. They attack by throwing eggs and even dashing at high speed. It can be damaged in any manner except jumping and hammers unless it's dashing. It has 5 HP, but every hit has it encase itself in a hard egg and roll around at high speeds for 7 seconds before breaking out.
 * The Menacing Machine (Boss of World 7): The final battle against Napoleon Knight and Princess Onyx. It is piloted with both of them in separate cockpits. Napoleon Knight pilots the cockpit that shoots fire while Princess Onyx pilots the cockpit that shoots ice. Each of them have 3 HP, but are immune to most attacks except to stomps, hammers, and lightning. Damaging a cockpit causes it to seal up and be invulnerable. When both are sealed up, the attacks become faster for 10 seconds, which afterwards, go back to normal, but more frequent while the cockpits open again.
