well o boi, theres a reason spoilers are in the title now ig, this is a big one.
so the premise is that some french dude working as a graphic designer at a manufacturing firm (which was found out cuz he left his name on his post) had murals of the smash roster. he posted the pictures of the smash mural onto his snapchat along with other things, including an upcoming grinch movie, and whats interesting about this mural is that it has unrevealed characters in it. in total there are 7 characters; 2 clones in ken and shadow, and 5 newcomers in isaac, chorus kids, mach rider, geno, and banjo-kazooie. not only that they also had original renders nowhere found on the internet, same thing for the promotional art of the grinch movie, there was art nowhere to be found on the internet. so if this leak was fake that means he'd have to draw the renders of unrevealed characters, move the existing characters on the roster to make space for them, then have the mind to think of making some promotional grinch art. while its not confirmed this is fake, its very likely that he didn't spend time making a bunch of renders and instead just posted the smash mural on site, and instead that this is real and what we're gonna get as our roster.
now that we got our alleged final characters, im gonna say, im really happy with these inclusions, i was already satisfied with our roster since we got ridley krool and simon, but this only adds on to the delicious cake that is smash5. all of these (bar mach rider) have been highly requested characters so they eventually made it onto my want list. as for mach rider, im really intrigued, hes excitebiker with a gun which im a fan of, i hope he uses his bike for almost all his moves cuz that be really cool to play as. these five characters can also potentially come with their own stage, which bumps it up to 108 just like the corocoro leak earlier. although theres no bandana dee or funky kong, im still glad that this is gonna be our roster, just wish these didnt get leaked though.
