Super Smash Bros Heroes

This is other idea. It gonna be a mini series (in case I haven't got much ideas for the other stories or stuck), just like those Dragon Ball Heroes animations but it main focused on Smash Bros. Also, in the third option, if asked nicely to and if I could add their stories to small scenarios as what ifs. There will be more than 300 characters, 200 from Nintendo, 100 outsides them. There are also hero and heroine avatars too: human, Kirby, Pokémon, swordsman and Animal.

Here are some ideas I had so far.

Sagas:
Smash Bros:
1. Welcoming: The hero and the heroine reached for a new wii u console and put on their amiibos. But then on the screen, Kirby and Pikachu calls for help and then the hero and heroine found themselves in the game wearing different clothing and teaming up with Mario, Link, Samus, Pikachu, Kirby and Donkey Kong fight Ridley
2. Andross and Star Wolf: Wolf O'Donnell and Andross are start making havoc on Concerica, so the hero, heroine, Fox and Falco came to stop them. At first they did well fighting against Wolf but Andross proved to be a problem. But then Slippy, Peppy and Krystal appeared to help.
3. Bowser: With Mario and Bowser locked in battle, the hero and heroine raced to find the captive Peach and face off against Bowser JR and the Kooplings. But when Bowser caught up to them and about to finish them, Mario, Luigi and Yoshi saved them and the three launches themselves at the Koopa King
4. Mewtwo: A Pokémon hero is seen walking through the streets. When Mewtwo and some other dark Pokémon attacked the town, the hero and heroine, with Pikachu, Lucario and Charizard rose to stop them and so did the new Pokemon hero.
5. King Dedede: King Dedede was stealing food till the hero and heroine stepped in front of them with Meta Knight. Dedede attacks them but after a while, Kirby appeared and they gang up on Dedede.
6. Ganondorf: Ganondorf is seen fighting against Link and Zelda. The hero and heroine, desperately want to help Link who is losing, then reveal their true power and managed to distract Ganondorf for Zelda to heal Link and then he joins them to take down the Evil King.
7. Tabuu: Tabuu has Bowser, Ganondorf, Mewtwo, Wario, Ridley, K. Rool, Wolf and other villains helping him as the heroes all stood against them. After an even match, Tabuu tries to defeat them with his Off Wing Attack, only to be stopped by Ness, Lucas, Marth, Ike and Roy's arrival.

Third Parties:
1. Sega and Capcom: As Mario and the hero and heroine faced off against Bowser; Eggman and Wily were watching from the background as both Akuma and Masked Lumen appeared and about to finish off Mario and Luigi, but then Sonic, Megaman, Ryu and Bayonetta appeared, getting their attention.
2. Namco Bandai: As Hades appear in front of the hero, heroine, Pit and Palutena, he summoned Spooky and Kazuya Mishima. As Pit was cut off guard by Kazuya's attack, Paultena called Megaman and Ryu as well as the new heroes, Pac-Man and Jin Kazama to stop Hades' plan.
3. Mircosoft: Gruntilda joined forces with Black Shadow to try to take down the Hero, Heroine and Captain Falcon. But then Banjo, Kazooie, Conker and Blinx appeared and attacked them causing the three to be suprised.
4. Playstation: Specter, Erol, Nefarious and Neo Cortex has kidnapped Peach, Zelda and Krystal forcing Mario, Link and Fox to try to save them until Kratos, Nathan Drake, Sackboy, Parappa, Spike, Jak, Ratchet and Sly to appear. As Crash and Spyro watches on, the heroes join forces and attacked the villians.
5. Square Enix: Sephiroth appeared from the sky, confronting Link, Marth, Shulk and the hero and heroine. He then attacks them without mercy. As the heroes rose again from his supernova, they turned to see Cloud arrive with Lightning, Squall and Tidus.
6. Shonen Jump: Mario, Link, Pikachu, Samus and the hero and heroine faced off against Broly, Madara, Teach, Aizen and Shisho, losing but just then they all turned to see Super Saiyan Goku, Kyubbi mode Naruto, Third Gear Luffy, Kenshin, Toriko, Ichigo and Guilmon appear.
7. Smash third party characters: Mario, Link, Samus, Pikachu, Kirby and Little Mac joins Sonic, Pac Man, Megaman, Ryu, Cloud and Bayonetta fight Master and Crazy Hand while the hero and heroine watched. Then Solid Snake returned and joins the battle, alongside Olimar.

Other sagas (What If scenarios):
1. KingAsylus91's Heroes of the Stars crossover: Someone tried to interfere with someone's else series, so the hero and heroine arrived in one animation series and helped Mario, Luigi, Yoshi and Bowser face off against Princess Shroom and her minions
2. Alvin-Earthworm-SMBZ's Super Mario Bros Z crossover: Mecha Sonic have gathered the Chaos Emeralds granting him his compete form. The hero and heroine join forces with Mario, Luigi, Sonic, Shadow and Yoshi who used the Dream Stars to power up themselves.
