Do you guys want to take turns writing a new Subspace emissary with Sm4sh characters?
First we'd focus on a separate group of characters--
I'd put a Dojo in the beginning with Ryu as the master
Ryu's disciples are
Greninja
Captain Falcon
and
Donkey Kong
You get to chose one character and battle against the other two--then finally Ryu
Then Ryu gives you a sacred Red orb (there 5 different color variations of these orbs) as your gift for being his successor.
Then when everyone is prepared to leave and the successor opens the door, ROB and Luigi are there dressed in mailmen suits (they are mailmen). From the get-go, it's obvious that Luigi is the new guy and he stumbles around with the mail, dropping it on the ground. ROB picks it up and offers it to Luigi, but when Luigi tries to grab it, ROB keeps his grip just to mess with the new guy. ROB quickly gives the mail to Luigi as the the driver of the Mail Kart, Jigglypuff, comes in to see what's taking so long. He scolds Luigi until he sees a shiny red orb in the hands of the successor, he orders ROB to grab and the two take off, leaving Luigi behind. Ryu points in the direction they went, signifying for the player to catch them--starting a mini-game where you chase after the kart, throwing various items at it and avoiding dangers until it is destroyed. Once it's destroyed, you fight Jigglypuff and ROB
