This was really awesome, I really like it! I hope to see more of this and whatever movies you have planned some time in the future. I also have an idea for a Toy Story cast.

Woody: Link
Buzz Lightyear: Pit
Mr. Potato Head: Mario
Slinky: Duck Hunt
Rex: Yoshi
Hamm: Kirby
Bo Peep: Zelda

That's all I've got for now. Anyways, this is really interesting and I can't wait to see more!

I'm begging you, update!

Drat, got cut off. In any way, still, the imagery of Lucina going into battle on a Gogoat is pretty hilarious. Not that she would need one. But another thing I have to wonder is why the king is ambiguous. Did you just have no good candidates, or do you plan to make it a reveal? Is it Marth?

I don't remember exact details of the movie, but is Sothe the one guy who got burned with "The only woman who loves him is his mother" in "A Girl Worth Fighting For"? If that's the case, Sothe makes even less sense here, considering how he's the super honorable type of character. Even if he isn't, why him of all people? I should comment on the chapter, but this just confuses me. And not much happens here anyway.
Also, Bowser Jr's name doesn't make sense in this universe, but I guess that couldn't be helped. Still, Mushu to my knowledge is a Trickster Mentor character, and Jr., the spoiled brat he is, isn't exactly a perfect fit, but in particular for Mushu's more mature side.
Still

The selection of characters here... was also extremely random. It's especially weird how Lyn, a female character, is among the ancestors, and speaking out against the others. I know they're supposed to be all Assist Trophies, but it doesn't make much sense in the context of the story. There's also a distinct lack of Marth here, too. You know, the man who is Lucina's ancestor. I was expecting him to be there, was dissapointed. Since you had Sothe there, I'm assuming you're fine with non-Smash characters, so maybe I would have had Sigurd and Seliph there; they aren't canonically related to Marth, but I wouldn't be shocked if they were. I would have had them summoned by Einherjar cards for extra FE references, though Trophies works fine since this is a Smash fic. I would have also said Ike and Roy if I didn't think they should appear later. Maybe include a gag about Sigurd being on fire. Speaking of, this fic seems to mostly copy-paste the scripts of the original. It would have been good if you had some variation; for example, I had this very idea, but Xane, a sort-of Manakete shapeshifter who would be playing the part of Mushu, is going to be secretly followed by the spirit of Marth, who somehow finds out about Xane's escape but doesn't tell it to the others because he's such a nice guy, but doesn't trust him enough to leave him with Lucina. (Xane: "I'll bring 'er back a war hero! Then the'll accept me back..." Marth: "Xane." Xane: "Wha-wha- PRINCY?! Eh, eh, nice t' see ya here, nice night isn't it-" Marth: "Shhhh... I have heard everything. But I will not tell them." Xane: "R-really? Then, uh, why are ya here? She's gonna be too far t' reach if we're wastin' time talkin'-" Marth: *grabs him* "I do not trust you enough, however. I'm going with you." Xane: "...Of course ya don't. Fine, fine, let's git a move on.") I never thought of Luma as the cricket though, for some reason. Good on you there.
Also, Robin, Ike, and Marth better show up. And your writing still leaves much, MUCH to be desired.

Oh, by the way, why were there cars in the last chapter? I thought this was a medieval setting?
And why is male Morgan here? He should be able to serve in the army here, logically, and it opens up a gigantic plot hole. And I'm still curious; why Sothe? Unless Micaiah is secretly the king of Yilisse (by the way, the correct term is Exalt), that seems really random. And judging by the gender struggle, the Exalt can't be Micaiah. If this is a Yillisean knight, I would have expected Frederik. And where's Lissa and Emmeryn?

Mario as the matchmaker? That was... not expected either. Nor the part about Rosalina of all people being Lucina's mother. I was expecting one of the Shepherds; and judging from Morgan, I was expecting Fem!Robin.

...Sothe? Huh, was not expecting him. I couldn't imagine him being a loyal knight to anyone but Micaiah. Still, it seems you've done some research on FE since The Great Smash Bros Adventure, which is good. I suggest you rewrite this once your skills improve, since honestly they still leave a lot to be desired.

awesome! Again, I love your cast of characters! I wonder if Lucina will pretend to be Marth!

Awesome! I love your descriptions! So detailed!

Another awesome chapter! I think I would have made the orb a different color to be more enticing to Zelda. Maybe a glowing purple, or something? Just my opinion. :-)

Nice story! Who is Rosie?

I has a suggestion, maybe toy story if that's alright? Merio can be Woody and Sanic can be Buzz

"Uhhh, yes, I just woke up. I'm Manakete, good morning. I will now go and fetch Lucina. Did I mention that I'm Manakete?" XD I'm dying there

WHY IS I TYPE IN CAPS IDK BUT STILL THIS IDEA IS GEENYUS
