Battle between six dark beings from different franchises.
Shadow Kirby[]
Shadow Kirby is first seen in Kirby & The Amazing Mirror, where he is seen to attack Kirby many times, only to get defeated by him and go back into hiding. In the battle between Dark Mind, it's revealed that Shadow Kirby was only trying to protect the Mirror World and thought that Kirby was a threat. We can see this, when Shadow Kirby throws Galaxia (Meta Knight's sword) to Kirby when he doesn't wield the sword anymore. After Kirby defeats Dark Mind, Shadow Kirby says goodbye to him as Kirby, Red Kirby, Yellow Kirby and Green Kirby leave the Mirror World. Shadow Kirby then returns in the Kirby Fighters subgame in Kirby: Triple Deluxe. In this game, he seems to be much more powerful, and doesn't just run away. He fights Kirby with the same Copy Ability that Kirby wields. Shadow Kirby also returns in Kirby Fighters 2, where he fights Kirby twice (in Chapter 4 and the Final Chapter). Here, he also fights Kirby with the same Copy Ability that Kirby uses. In the second battle, it says that he is pulling a prank on Kirby and doesn't actually mean to fight Kirby in a bad way.
Shadow Kirby looks completely identical to Kirby, body shape and all. In Kirby & The Amazing Mirror and Kirby Star Allies, he has a gray body color, black feet and a white mouth. In Kirby: Triple Deluxe, his design changes, he has a nebula body color, nebula feet, and pure white eyes. In Kirby Fighters 2, Shadow Kirby's design is similar to Shadow Kirby's design in Kirby: Triple Deluxe, has has a shiny gray body color, silver feet, pure white eyes, and a white mouth.
Being Kirby's Mirror World counterpart, Shadow Kirby is very strong. He wields the same power as Kirby, inhale. Shadow Kirby can inhale his enemies, and spit them out. He can also use Copy Abilities, like Kirby can. Also, Shadow Kirby can summon the Warp Star, which can move faster than light. In terms of speed, Shadow Kirby seems to be slightly faster than Kirby, and can even use many attacks at once at high speed, making it difficult for his opponent to dodge his attacks. In terms of durability, Shadow Kirby is very durable, as seen when he fights Kirby in Kirby Fighters and Kirby Fighters 2, where he has a bigger health bar than Kirby.
Dark Meta Knight[]
Dark Meta Knight was first seen in Kirby & The Amazing Mirror where he attacks Meta Knight who tried to save Dream Land and throws him into the Dimension Mirror. He is first encountered by Kirby in Radish Ruins. Where he disguises himself as Meta Knight to fool Kirby. After the battle, Dark Meta Knight's mask breaks and his Meta Knight colors changes back into his original colors. Dark Meta Knight then flies away (leaving his sword as well) while Kirby gathers the mirror shard that Dark Meta Knight dropped and attaches it to the Dimension Mirror. Once the Dimension Mirror is completed, Kirby and his three clones go into the Dimension Mirror to fight Dark Meta Knight. Dark Meta Knight goes towards Kirby and his three clones and tries to fool them by changing his colors to Meta Knight's colors. But the real Meta Knight shows Kirby, Red Kirby, Yellow Kirby and Green Kirby that Dark Meta Knight is trying to fool them. Dark Meta Knight then switches back to his original colors and then fights Kirby, Red Kirby, Yellow Kirby and Green Kirby. Once he is defeated, he shatters and a portal sucks in Kirby and his three clones, which leads them to fight the true evil mastermind, Dark Mind.
Dark Meta Knight has some really powerful moves:
Dark Meta Knight can slash like Meta Knight can and can also shoot out Sword beams. When charging his sword for long enough, he can make an enormous tornado that can send anyone up but it disappears in a short time. Dark Meta Knight can guard defending him from some attacks. He can fly, jump and suddenly fall straight down with his sword pointing to the ground. And he can also stab his sword into the ground to summon giant swords.
In Kirby: Triple Deluxe, Dark Meta Knight gets even more moves, most of them are the same in his first phase, but in his second phase, he summons a mirror around him, clones himself and attacks at the right time. After a while, he and the clones will jump out of their mirrors and will glide down in the direction of the player hoping to damage them.
In Kirby Star Allies, Dark Meta Knight can summon a wall around himself, defending him from attacks. He can also summon up to six clones of himself right next to him which pop out and damage any nearby enemies.
Shadow Dedede[]
Shadow Dedede appears in Kirby: Triple Deluxe. In this game, he is fought in the subgame Dededetour after King Dedede defeats Queen Sectonia DX (he can also be fought by Kirby in The True Arena). Once he is defeated, the player moves on to fight Dark Meta Knight.
Shadow Dedede is very aggressive towards his opponent, as seen when he fights King Dedede. He is the Mirror World counterpart of King Dedede as he comes from the Dimension Mirror. Shadow Dedede has a similar appearance to the regular King Dedede. Though Shadow Dedede's clothes and skin are black and red. His eyes are also pure white while the regular King Dedede's eyes have pupils. Shadow Dedede appears to be King Dedede's strongest clone yet. Having abilities far beyond than the regular King Dedede has.
Shadow Dedede has a lot of OP moves:
First of all, he can run at the player at very high speed and can jump very quickly too, making it hard for the player to dodge him. He also wields a hammer similar to Masked Dedede's. He can damage the player by bashing it at them for a while. And can even create huge shockwaves out from his hammer smashes. He has a much stronger inhale than Kirby (similar to King Dedede's inhale in the newer Kirby games) and can suck up his opponent. He can open his hammer and can shoot missiles or purple fire from it.
But Shadow Dedede's true terror is from his second phase, where he summons an enormous axe. With this giant axe, he can spin it around and slash at his opponent at high speed. Also, when he jumps he creates huge shockwaves that move around the area, which makes it hard for his opponent to dodge him or the shockwaves. He can shoot powerballs from his axe which move around the area, and can charge his axe and smash it onto the floor to make huge purple explosions. But you haven't seen anything yet, Shadow Dedede can open his STOMACH, and shoot giant (when I say giant, I MEAN GIANT) purple balls from it.
Dark Bowser, Dark Star, Dark Fawful[]
Dark Bowser appears in Mario & Luigi: Bowser's Inside Story where he is created by Fawful using Bowser's DNA. When Dark Bowser was created, he didn't have a full body. However, after he inhaled Dark Fawful, he finally got his full body and tried to use the dark power to destroy the Mushroom Kingdom. That was until Bowser stepped up and fought Dark Bowser, while Mario, Luigi and Starlow fought the Dark Star & Dark Fawful Bug in Bowser's body after Bowser inhaled Dark Fawful Bug. When the Dark Star & Dark Fawful Bug were defeated, Dark Bowser was also defeated, allowing Bowser to end the battle with one K.O. punch. After this, Dark Bowser explodes and peace returns to the Mushroom Kingdom.
Dark Bowser is very powerful, being a dark clone of Bowser himself, who has survived galaxy explosions, black holes, being thrown into the sun, and his own castle collapsing on him. Bowser has also be shown to outpace a black hole and proven himself to have immaculate physical strength, as he can smash through bricks with no difficulty whatsoever.
Dark Bowser has all of Bowser's abilities along with a few of its own. He can breathe blue fire, inhale, punch and curl into a ball. He also can create a large boulder, toss it into the sky, and break it apart with a fireball, causing flaming rocks to fall from the sky. He can also entrap Bowser in a cage of black lightning and throw a large energy ball at him. When defeated, he is instantly revived by the Dark Fawful Bug and grows larger. He then throws a ball of dark enemies at Bowser, knocking him back and forcing him to fight the enemies to get to Dark Bowser he has 1000 Hp.
It can be very difficult to defeat Dark Bowser as the Dark Star Core must also be killed, which can be a problem if it's hiding. This means that the opponent has to find the Dark Star Core while fighting Dark Bowser, making it somewhat impossible for someone to fight Dark Bowser in a 1v1.
