Dark Star

"It was not benevolent. It was a frightful star that hid a great evil."

- Princess Peach

The Dark Star is an artifact featuring prominently in Mario & Luigi: Bowser's Inside Story. Long before the time of the game, it was hidden away beneath Toad Town due to its Powers of Darkness.

Mario and Luigi: Bowser's Inside Story
During the events of Bowser's Inside Story, the Dark Star was stolen by Fawful in order to fulfill his plans. He uses its power to barricade the front door to Peach's Castle allowing him to use it as a stronghold during the game. Mario and Luigi eventually use the Miracle Cure to destroy the barrier.

When Bowser confronts Fawful and Midbus near the end of the game, the Dark Star escapes from the machine that Fawful has been using to drain its power. While Bowser is distracted fighting Blizzard Midbus, Fawful absorbs some of the Dark Star's power and is converted to Dark Fawful. He flies off in search of the missing star. However, while he is gone, the Dark Star returns and invades Bowser's Body. Thus, Mario and Luigi venture to the final unexplored area of Bowser's body, Airway. Here, they discover the Dark Star absorbing pieces of Bowser's DNA. They attempt to capture it several times, but each time it escapes using one of Bowser's powers. Starlow theorizes that it is somehow incorporating Bowser's DNA into its own body.

Eventually, the Mario Bros confront Dark Star at the very back of Air Space. They attempt to destroy it, but it simply escapes from Bowser's body. Outside, it transforms into an apparition of Dark Bowser and escapes, freeing Bowser from the room he was trapped in in the process.

Later, when Bowser defeats Dark Fawful, he becomes a small blob of dark power,the Dark Fawful Bug, and escapes. The still incomplete Dark Bowser absorbs Fawful and uses the power he took to complete his body.

The Dark Star's final appearance is during the final battle. After Bowser does critical damage to Dark Bowser, what remains of Fawful heals him fully and causes him to double in size. At this point, Bowser attacks Dark Bowser's belly, causing him to expel Dark Fawful. Bowser absorbs Dark Fawful for the Mario Bros. to handle. Here, he transforms into a giant insectoid mass of dark power, still with his manic grin and now crimson eyes. His only weakness is the Dark Star Core, which sits on an antenna high above his head. As with the final bosses in the previous two games, Mario and Luigi must progressively disable the different parts of Dark Fawful before attacking this weakness. It is likely that it still has a distinct intelligence from Fawful's, since he is visibly displeased whenever it decides to flee.

Dark Star reappears in the Gauntlet as Dark Star X. It costs 2500 coins to battle and must be defeated in twelve turns.

Battle
In battle, the Dark Star can not usually be damaged. To expose its vulnerability, the Marios must destroy the Dark Satellmites that surround it. With sufficient damage, the Dark Satellites will use a Kamikaze attack that consists of throwing a bomb at one Mario brother, and throwing their own body at the other. Ordinarily, both will miss, but either brother can attack the projectile launched at him. If the bomb is attacked, it will explode, doing damage to Mario and Luigi. If the satellite is attacked, it will be knocked flying into the Dark Star. After being hit in such a way twice, the Star will become vulnerable and immobile for several turns.

Attacks
One of the Dark Star's attacks consists of it splitting into five as a thick fog fills the battlefield. Each Dark Star then flies slowly at a Mario Bro, vanishing into the fog as it draws near. The Marios must counter this attack by using their hammers on the hidden Stars.

In another attack, the Dark Star will shine a bright light at the Marios, causing their shadows to come to life. The shadows will then move in a circle around the Dark Star, which will attack them with beams of electricity. The Mario Bros. must jump to avoid the electricity, as any damage done to the shadows will hurt the real Mario Bros. as well.

The Dark Star may also send red and green energy balls into the air. It will then fly through these balls in order, sending them at the correspondingly colored brother. They may be countered using the hammers.

When the Dark Star has been immobilized, whoever attacks it, it will shoot out a laser to the bro. who gave the order to attack.

After receiving sufficient damage, the Dark Star will use a laser attack that fills up the entire touch screen. Starlow will appear just before this attack activates, suggesting that Mario and Luigi grab on to her. When they do so, Starlow will fly up in the air (top screen) therefore avoiding the attack. After the attack is through, the Dark Star will look up and attempt to ram into the bros. The Mario bros. must release their hold on Starlow to avoid making contact with the Dark Star.

Just before it is defeated, the Dark Star will use a vacuum attack on both Mario and Luigi. This must be countered by pressing A and B repeatedly or the brothers will take massive damage. The Dark Star will then be defeated.
