Guys, I bet you didn't know this.

Trollhunters was originally a novel, a horror-fantasy novel, a good one at that.

Most of the characters have something in common with X-Men and Marvel characters.

In the novel, it was Jim Jr's mother who left him and his father who found the amulet.

Jim is ambidextrous.

Jim is the first to survive the deep, second being Krel from 3 Below.

Jim is 5'6.

Claire was originally Scottish.

In the book, Claire was a descendant from a Trollhunter.

Claire is allergic to dust.

Claire is not visibly seen in 3 Below, only mentioned in two episodes.

Claire uses the Shadow Staff as a Quarter Staff most of the time.

Toby was originally Tubby in the novel.

Toby manages to destroy 8 cell phones in both series, Trollhunters and 3 Below.

Toby is 5'1.

It is a running gag to insult Toby's braces.

Blinky originally had eight eyes and was blind, and had tentacles, 12 tentacles.

Blinky had a relative that was a Trollhunter, featured in a comic.

AAARRRGGHH!!! was originally a female.

AAARRRGGHH!!! was the first character to be revived, followed by Angor Rot.

AAARRRGGHH!!! is the only Kruberan with fur.

Draal is the fourth character on the side of good to be killed off, the first being his father.

Draal's age is the only one that is actually stated, a young 1200 years old. 

When he dies, Draal is the first non-Trollhunter to reside in the void.

NotEnrique doesn't have an actual name.

Steve was originally a Changeling.

Steve has had the most character development across the series, including Trollhunter, #Below and the up coming Wizards.

Stricklander is the first major villain to reform in Trollhunters.

Stricklander is supposedly a good swimmer.

In the book Barbara abandoned her son.

Queen Usurna was the only member of the tribunal to turn out evil.

The queen is described as a sadist.

Vendel was the third character on the side of good to be killed.

Kanjigar was the first to die on the side of good.

Nomura's first name is Zelda.

Angor Rot was never actually a villain, but an actual hero to his kind.

Gunmar is reduced to a minor villain, stepping aside for Morgana Le Fey.

Morgana was based off Arthurian mythos.

Morgana looks human but is described as 'something else'.

Morgana is pure evil.

Morgan is one of Dreamwork's most deadly seven villains, sort of like the seven deadly sins.

Merlin is an ass.

Merlin is the same name in Arthurian folk lore.

Luke Skywalker voices Dictatious aka Mark Hamill.

Dictatious is the only villain to be related to a main character.

Originally, Dictatious was going to be killed off, but the writers liked Mark Hamill's performance so much that they kept him alive to reform him.

Dictatious was similar to the Joker, because they had the save voice actor and voice.

That was fun, hope you enjoyed my fun facts.
