Bowser has kidnapped Princess Peach!
It is up to Mario, his brother Luigi and Princess Rosalina to get to his fortress and rescue her! But be wary for his Koopa army is standing in your way and is also chasing after you. Upgrade your ship and get to the Warp Pipe before they catch up! There are no extra lives on this one!
Yup another one of my half-assed ideas that'll probably never get past the concept stages.
But what if I was to change the backgrounds and rewrite events and stuff so it's like you're Mario chasing after Bowser? The Rebel Fleet would be replaced by Koopa Troopers, Missiles would be Shells, Drones would be I dunno, Lakitu clouds with different loadouts?
So yes, maybe an artillery weapon that could be used by a ship is the infamous Blue Shell and maybe a Big Bullet Bill and those Chomps from Yoshi's Island.
The music for the Last Stand would most definitely have to be one of Bowser's boss themes (Airship theme, or something from Super Mario Galaxy?) and the final boss fight would be against his flagship, which the Power Surge warning sounds become his laugh.
Then there's the idea of what the aliens should be...
Naturally the Crystals would be made into Mario, Luigi and Rosalina. Because Gencool does it for unique characters.
Humans could be Toads I suppose. Or the Ghosts could be that considering how fragile they are (or would Ghosts be Goombas?)
Mantis might be Koopa Troopers. Engies could be Yoshis, because they're really handy to have but pathetic when it comes to battle and prone to being sacrificed for that extra jump.
I dunno who the others could be, I'm not well-versed on advanced Mario lore, only the classics.
