Fantastic Beasts & Newt Scamander

Explanation: Newt Scamander. Author of "Fantastic Beasts and Where to Find Them", a Hogwarts textbook in the main saga. He travels the world to study magical creatures and protect them in his magical suitcase.

Explanation: Magizoologist. A specialist in magical creatures — studying, protecting, classifying them. He travels the world gathering specimens in his magical suitcase with multiple inner habitats. Unlike the Ministry, who wants them exterminated, Newt advocates protection.

Explanation: New York, in 1926. Roaring Twenties atmosphere, Prohibition, jazz. Newt arrives with his magical suitcase and meets Tina Goldstein (a demoted Auror) and Jacob Kowalski (a Muggle/No-Maj worker). MACUSA (the American Ministry equivalent) hunts Newt for releasing creatures.

Explanation: Hufflepuff. His values — loyalty, kindness, hard work, and love of creatures — perfectly embody Helga's house. He is one of the rare Hufflepuff main heroes in the extended HP universe (along with Cedric Diggory, Nymphadora Tonks).

Explanation: A Niffler. Platypus-like snout, black fur, magical belly pouch holding infinite stolen items. In the first Fantastic Beasts film, the Niffler escapes and ransacks a Muggle jewellery shop — the first creature Newt has to recover.

Explanation: An Occamy. Half-snake, half-bird with blue-green feathers, it's "choranaptyxic" — it magically fills any available space. Newt raises several in his suitcase. Their eggs are pure silver, making them extremely valuable and sought after.

Explanation: Jacob Kowalski. A WWI veteran hoping to open a bakery. He becomes the first No-Maj to officially enter the wizarding world in America. His relationship with Queenie Goldstein (a Legilimens witch) is one of the saga's most touching.

Explanation: Credence Barebone. Raised by Mary Lou who abuses him, he represses his magic until becoming an Obscurial — a parasitic entity of pent-up magic that destroys everything in its path. The 2nd film reveals origins tied to the Dumbledore family.

Explanation: Queenie Goldstein. She reads minds naturally, making her a priceless asset. Her forbidden love (wizard/No-Maj relationships are illegal in 1920s US) with Jacob Kowalski becomes the saga's emotional heart. She temporarily turns to Grindelwald out of despair.

Explanation: MACUSA (Magical Congress of the United States of America). Based in the Woolworth Building in New York. Led by President Seraphina Picquery in 1926. Laws stricter than Britain's: strict wizard/No-Maj separation, mixed marriages forbidden.
