Voldemort's team

Bartemius Crouch Jr.: a skinny, pale youth with straw-colored hair and a cheerful, almost boyish face. In the film, the role was played by David Tennant, and the image is slightly different: dark, tousled hair, a nervous expression, and a twitching tongue that he constantly licks.
Personality: Fanatically devoted to Voldemort—perhaps even more so than many of the old guard Death Eaters. Charismatic, cunning, and a brilliant actor: he successfully impersonated Alastor Moody for a year without giving himself away. At the same time, he is cruel and merciless: he killed his own father and showed no remorse. Unstable—his emotions swing from rapt adoration to hysteria. His greatest tragedy is that his father essentially rejected him, and all his devotion to the Dark Lord became a substitute for the parental love he lacked.
Grindelwald: a handsome young man with golden hair and a cheerful, bold face. In old age, he became gray and haggard, but still retained his majestic appearance.
Character:
Gellert Grindelwald is one of the most charismatic and controversial antagonists in the Harry Potter universe.
Character traits
Conviction and fanaticism. Grindelwald sincerely believes that wizards should rule the world—not for personal power, but because he considers it the "greater good" for everyone. His idea sounds almost like a mission: he sees ordinary people (Muggles) as a threat or as those incapable of controlling their own destinies and therefore must be under the protection of wizards.
Charisma and oratorical gifts. He knows how to ignite people, inspire them, and lead them. This is precisely why he attracts followers: he doesn't simply command, but infects them with his faith. This is especially noticeable in the Fantastic Beasts films—his speeches sound like manifestos, almost like political speeches. Cold calculation. For all his ardor, he is very rational: he knows how to manipulate and calculate his moves. He lacks empathy. He is capable of cruel acts if they serve his greater purpose.
