While Hiccup's fire sword looks fictional, a Youtube video called: "FIRE SWORD from How To Train Your Dragon!" made by the Hacksmith shows that sword can be made into reality by modern tech with police batons and propane(instead of Monstrous Nightmare saliva)! Wish Alex McKain Hendrickson has her own sword that is similar to Hiccup's but made of Titanium or other lightweight yet much tougher materials and has the ability to use liquid nitrogen to create ice attacks.
P.S. this video also said Hiccup has literally becomes Steve Rogers (MCU one) from very weak guy to a toughen up expert!

Eh Steve, I think u should reconsider why u said some "petty person" are "insercure in themselves" and making "unkind comments". I like those fanfics very much plus her work is amazing, but I have to agree Peter HK. He is right for we don't know the type of dragon class Snowfire's White Terror species is and he is not letting people down but puting suggestions whether u like it or not. He is just too excited about the future fanfics so he made lots of those comments. Please respect other's "ideas" sir by not calling them petty or other things.

Hi, I'm Steve. Fanfiction is all about amature writers taking a story and giving it twists to reflect your ideas and personality. I am NOT a good writer therefore I rarely criticize. I think your writing is wonderful and I am enjoying the story. You write fanfiction because you enjoy it. Don't let a petty person get you or your other writer friends down. This person obviously is insecure in themselves and needs to feel better by making unkind written comments. I am an old man and the only advise I can give you is "don't sweat the small shit". You have a talent you like to exercise. I like reading your stuff as I'm sure many others do. If you make one person smile with your work you're a success. Have fun and keep pressing on.

Your friend,
Steve

While I am a fan of The Paradigm, White Dove Fly High and Thunder. Yet we never know what type of Dragon Class and exact length(maybe I forgot where it was) is Snowfire's White Terror species in the bio.
Is her species Tidal Class or Strike Class?
Plus in the future sequel of Thunder ending chapter, please make Alex & Hiccup's both kids' hair colors differently from the film(where Hiccup and Astrid's kids and in the possible future fanfic are the same size) and both getting the ability to change to Night Furies like Alex?

From Peter Hong Kong

wow hiccup is determined even though he will realize his father was right and at the cost of his father's life.

Cool, love it! After u watched The Hidden world, please update or remake a series that Hiccup and Alex marry each other like the scene from the movie?

OK... Wish u can update Thunder or make its sequel as soon as possible.

Will we see the whole image of Alex McKain Hendrickson? Due to can't image her the clothes or armor she's wearing during her years after seeing Snowfire . And who drew Alex's face? Moreover u know Toothless and the female Light Fury will give birth to 3 kids which are Night Lights?

Plus will Alex use a Joint Special Operations Command version HK416 Carbine(D10.5RS barrel, 30 round 5.56 NATO Magpul magazine, Magpul Angled Forward Grip, EOTech Holographic Hybrid Sight with Magnifier, ATPIAL [AN/PEQ-15] - Advanced Target Pointer/Illuminator/Aiming Laser and SureFire FA556-212 Sound Suppressor) as her primary assault weapon and an M45A1 Close Quarters Combat Pistol(71 45 ACP Wilson Magazine, Walther Night Force rail mounted tactical light/laser sight, 3-dot Tritium Night Sights, G10 Desert Tan Grips and SilencerCo Osprey .45 Suppressor) as her sidearm during some missions or adventures in the future? Don't feel uncomfortable because I like modern military equipment.

wow this is going to be good.

can't wait for Aniu to see hiccup again?

Yay another chapter. Um well this is going to be interesting but I am thinking now that someone else beside Stoick is going to die. Keep up the great work.

Wish Thunder will include Avengers Endgame 2019! Where can will see Alex McKain Hendrickson's whole face or herself in painted art?

I dont blame you on the new spyro games I was planning on getting it for my mum for Christmas. Keep up the great work with the story.

wow poor hiccup he misses his girlfriend and Cybele misses her sister.

Will they meet soon hope its a joyful reunion?

will someone snap at Zena saying its her fault Aniu left?

That Youtube video is called [THE WHOLE STORY REVEALED!? How to train your Dragon: The Hidden World].

Although this is a BIG spoiler for The Hidden World in 2019, at least we know Toothless will have a good life with his wife and his kids. Plus explains why Hiccup said there were dragons!
