Undertale the singing movie

16. the final battle

we return to see the grand hall with Pyro behind a column until he heard footsteps and saw Toriel running in saying

Toriel: oh my, I sure hope Asgore isn't fighting Nitro again, please let him be safe

when Toriel left to the throne room Pyro saw Undyne run in saying

Undyne: oh man, if Nitro and Asgore are in a battle I'm going to stop it

when Undyne left the hall Pyro saw Alphys run in saying

Alphys: is that Undyne? did she say something about Nitro and Asgore fighting? please don't let it be too late

when Alphys left the hall Pyro's phone buzzed when he got a call, he flipped open his phone and said

Pyro: hello?

who he didn't expect to call him was Papyrus

Papyrus: Pyro, I know I would call Sans, but he and Doggo are with Nitro, how far are you from the hall to the throne room?

Papyrus yelped when he saw Pyro come out from behind the column saying

Pyro: I'm already here

Papyrus was surprised of what Pyro is in now and said

Papyrus: the others will be surprised about your new form Pyro, I just know it

Pyro just chuckled and the two went to the throne room ending the flashback and Nitro said

Nitro: I guess we'll be fighting more often, right?

Pyro then laughed and said

Pyro: you got that right!

Nitro then turned to his team and said

Nitro: looks like we'll be a team from this day forward

the team then turned to Toriel and the others to see them in a line going from left to right[Asgore, Undyne, Toriel, Pyro, Alphys, Papyrus] with Toriel saying

Toriel: it seems like that, you and your friends have made this the best birthday you ever had

before they can go home Alphys turned to Papyrus saying

Alphys: hey Papyrus, how were you able to get us all here?

Papyrus then stood in a heroic pose and said

Papyrus: let's just say, a golden flower helped me with that

Pyro then turned his head slowly to Papyrus with a worried look saying

Pyro: a golden flower?

just then a bunch of vines came out of the ground and pulled Toriel and the others into the air while pinning the soul team to the ground, Nitro then looked to what is in front of them and it is Flowey saying

Flowey: Nitro, it's so good to see you

Nitro then became shocked and said

Nitro: Flowey? how could you?

Flowey then summoned a bunch of pellets and aimed them at the soul team saying

Flowey: for you to know, I planned this all along, at first I wanted to take the human souls to become stronger but then when you came to the underground, my plan changed, with you around my plan would be ruined, but now, this is where it ends

Flowey then launched pellets at the soul team until all four of them were at 1 hp, Flowey summoned pellets around the soul team and said

Flowey: you're time in the underground is over, HAPPY BIRTHDAY NITRO!!!
