It's now canon that only jr is bowser biological son the koopalings are adopted apparently

That always bugged me if the master emerald is stronger than the chaos emerald than why doesn't eggeman just always go after the master emerald instead of hunting down 7 chaos emeralds instead of 1 much more powerful emerald

I totally agree with you shadow should be dark but not shadow the game dark

I feel like other smbz is based on this or this is based on smbz

I still feel like betraying bowser is something eggman would do

again another crossover done right.
3 reasons why that is.
1) Mario and sonic know nothing about each other.
2) nothing like ( oh I remember you from super smash bros brawl) or something like that.
3) it Mario and his friends meets sonic and his friends ( in other words no link or Kirby or any Nintendo character.)
I give this a 10 out of 10 two rivals meet for the first time ;)

Basically, same thing as last chapter. Could have used more wording and action. Although, I always imagine Mario and Luigi to... not so much be mute, but not talk much. That's just a way I view it. You also should have made fun of the fact that Peach is always being kidnapped here somewhere.

Also, it actually is supposed to be "So Long, King Bowser!" but that's what many fans interpret it as anyways.

Hm. Well, this is a decent chapter. Could have used a lot more wording in it. More action as well. And why did Amy just pop right out of the trunk?! You'd think that Tails would know if Amy was in the darn plane.

Really good story,
Sequel please?

when peach said ' i'll take my frying pan with me' i imagined her using it on kamek saying ' die kamek, die'

Before I begin this review, I want to let you know that this is not meant to be hateful, merely constructive criticism. I mean no offense to you personally by this; I am simply reviewing your work. I fully understand the desire and process of writing a crossover with Mario and Sonic, as I myself am working on one. With all that in mind...

The whole story feels a tad rushed. Not only is it only 13 chapters, but they are rather short chapters. I understand that you want to get straight to the point, as every good author should, but you barely lay anything out. True, there are times for the characters to sit around and talk, but even there, the dialogue and narration feels rushed and clunky.

One example of this is when Amy saves Sonic from Metal Sonic. You just flat out say, "Sonic realized right then and there how much Amy meant to him." How about going into it more? How about something about Sonic admiring Amy's strength and realizing just how far she's come from Sonic CD? And in that realization, start to warm up to Amy A LITTLE. I know it's Sonic the super-fast-about-everything hedgehog, but even he wouldn't realize something as monumental as realizing he's in love with Amy that fast.
Another example is the part with Donkey Kong. All he does is save Knuckles, beat up Waluigi, say one line, and goes off again. I understand you're trying to put the focus on a set group of heroes, but the one second in the spotlight for the other characters shouldn't literally be one second.

BUT, I do think there are a few creative ideas. For example, I like the idea of the Dark Star still having a "seed" inside Bowser, I like the idea of 2 monsters from both series coming together, I like the fact that you try to include several characters from both series (even if some of them only appear for a few paragraphs only to vanish like DK), and I like the danger of the two worlds actually colliding together. However, there were some sloppy ones, such as Shadow wanting to blow up Mario's planet (really? I know he's violent, but surely he has the sense to look for some other solution first) and Sonic dying only to be resurrected 10 seconds later (why kill off a main character if he'll be "right back after these messages", so to speak?).

Again, this is not meant to be offensive, just me as a writer offering my advice to another writer. I'd suggest giving this an analysis and rewrite, and I wish you luck on any future stories.

Best Wishes,
