Chapter 14)We finally meet up with Link who is walking though a Japanese forest (bamboo everywhere). Subspace foes attack. He rips though them, but when two of them try to sneak up on him, Takamaru shows up to finish them off. The two make their way though the forest. At the end, they see a sight of Bowser's Castle.
Chapter 15)Marth and Zelda are outside the gates to the castle. Below though, they see Marth attacking the guards outside. But he can't get though the now sealed heavy door. That is where Ike comes in, flexing his muscles, and breaks it down. Marth is a little agitated, but he follows the other two in. At the end, they make it to Bowser's throne room.
Chapter 16)Link and Takamaru go though a lava field and around the back side of the castle. They manage to break in the back and into Bowser's throne room. In trouble, he pulls a lever and a large Bowser Mech with Bowser Jr inside attacks. The 5 of them defeat it. They see that Bowser is gone, but a path opened behind his throne
Chapter 17)Bowser teleports back to the ship where Medusa and King K. Rool are waiting. Soon after though, small mysterious ships surround them. They attack and are soon boarded. The three make a mad dash to get off the ship. At the end, they are met with Mewtwo, who attacks them. Afterwards, Medusa sicks her underworld forces at them though a dark portal. As they fly off, more underworld forces try to buy time. Mewtwo is then revived by none other than Ganondorf, who gives a stern look. They move to the control room, and their ship is seen along side Meta-Knight's.
Chapter 18)Saki, Kind Dedede, and Meta-Knight are now in the mountains, and see both the enemies ship and his own. Next to them is a fallen Arwing. They are ambushed by a boss. It's Heavy Lobster, who is now under the control the the mysterious forces. Fox jumps out and joins the fight. Afterwards, he receives a message of some kind, with the other three staring at him and wondering what it's about. They finally reach the top and are greeted by the Great Fox. (BTW, it's a rocky mountain)
Chapter 19)DK, Dixie and Diddy found a giant factory after they beat their last level. They now go into it. Turns out the shadow bugs came from here. They confront Medusa, Bowser, and King K Rool who just escaped. At this point, you can chose who you want to fight with and you duke it out with he 3 of them. (If playing with 1 person, they fight one at a time. With 2 players, they fight two at a time). Either way, the mysterious foes attack. The team who won takes the three trophies as well as a yellow glass tube (that is big enough to hold a trophy huh). As the factory is lifted into the sky, Palutena's and Peach's trophies fall to the ground below.
From here on, the subspace foes are gone. I didn't mention, but you also fight foes from Mario, DK, Kid Icarus, and Kirby. Maybe more, like Zelda. It depends on the level. DK levels have DK enemies. Bowser's enemies appear in his castle and the sewer levels. You see Underworld troops during Pit's level's
Chapter 20)In Mario's last level, they found a strange platform. They step onto it and are soon it turns into an elevator which brings them down into a weird fortress (think Pandora's Labyrinth if you've played KI:Uprising). After making it though, the heroes find a room with a weird computer like device. They find out more about the dimensional foes (shown to the player via one screen pictures). They soon see a canon like device and a pyramid. They rush over to a tram that leads them to their next destination
Chapter X2)Toon Link's ship is being attacked by Meta-Knight and the subspace ship, it soon is sunk with Toon Link sent into the ocean. We washes ashore where Jigglypuff find him. They go off together after the subspace ship.
Chapter 21)Pokemon Trainer and Squirtle are in trouble. They are being attacked by mysterious foes (need a name for them). A vision of the future appears. Shulk rushes over to attack them before defeating Squirtle. The two then go off to fight more of them. They eventually reach a beanstalk like structure. Pokemon Trainer points to it and Shulk follows.
Chapter 22)Luigi is just whistling his way though a forest along when Dimension troop attack him. With Peach and Palutena trophies fall to the ground. He quickly awakens them and hides behind him. They defeat the foes. At the end of their level, Palutena looks around and points ahead, Peach nods and follows, but sees Luigi trying to sneak off. She give him a stern look and he follows along.
When. I have more ideas, but, another time. In a lot of ways, I'm just beginning. Not sure how realistic a story mode this size could be.
