Lets say sence SMBZ came out that mario and the his bro came to sonics world. Bowser messes with magic that he has no idea how to use. Peach warns Mario of what is happening and he goes over to stop him with luigi. They get there and Bowser is already done he just needs to use it to get the power he seeks. The two bros kick his butt, but set of a chain reaction that opens a portal to a new world. The three are sucked in and scatered in the new world. Lets say Mario lands at a beach (sunshine refrence), luigi at a hotel (kinda a massion refrence), and finaly Bowser in a place like the Aztec Ruins of the older games. Then Bowser is seen walking throught the wild then finds some Eggman's robots snooping around for anything. He crushes them with ease leting out a alert of destuction more come to see what happend. He fights them all off and Eggman thinks its sonic and finaly goes himself to see. Finding him; his sensors indicate that Bower has a unkown residue that has huge amounts of power that could rivial the chaos emeralds. They exchange pleasenties and decide to work together to end their hated foes. Ok then...hmm ok lets say Sonic and Tails find Mario at the beach fighting of some bad guys. Sonic gets too close and Mario gives him one good one to the face. Tails settles the fight before it got out of hand. Then for the fun of it let Shadow find Luigi cowering from place to place. Then they are ambushed by some enemys they both fight and Shadow is slightly impressed by how he fights but just lets that idea go when he trips on a broken robot. He leaves and Luigi just fallows behind just pissing him off even more. Well thats all I got for now till some new ideas pop in.
