Since Albus and Grindelwald had a blood pact, and they most definitely fought each other (Albus trying to stop Grindelwald from torturing Aberforth), probably Grindelwald's or Albus' spell was deflected by the blood pact, and accidentally hit Ariana, resulting in her death.
Dark wizard, Gellert Grindelwald stole the elder wand from wandmaker Mykew Gregorovitch. The elder wand is known to switch its allegiance to a superior wizard who overpowers the wand's previous master. Dumbledore obtained the elder wand by defeating Gellert Grindelwald the owner before him.
Unbenknowst to most, Dumbledore was actually unable to confront Grindelwald directly: in their youth, the two wizards had sworn a blood pact, sealed in magic, not to fight each other. The vial that had sealed the pact was kept by Grindelwald for years until it was stolen in 1927 by Newton Scamander.
Yes, Grindelwald met Voldemort, this wanted to know where Elder Wand was.
We're not really given much information about what Grindlewald did leading up to the famous duel with Dumbledore. Voldemort was more powerful than Grindelwald because: Voldemort's bloodline was far more powerful. He was the last descendant of Salazar Slytherin.
Not only that, but “The Crimes of Grindelwald” had the lowest box-office haul in the U.S. and internationally of any “Harry Potter” film. It made only $160 million domestically and just under $500 million in foreign markets.
Grindelwald, on the other hand, did not fear death, which made him more powerful in many ways. He wasn't limited by anything. There is an excellent chance that Grindelwald knew how to create Horcruxes, given his in-depth studies of the dark arts, but he never felt the need to make them, leaving his soul intact.
In November 2020, Depp revealed he will no longer play Grindelwald in the film series after he lost his libel case relating to abuse allegations by former wife, actor Amber Heard against a UK newspaper.
Without a sense of discovery, the series is already lost. Moreover, the Fantastic Beasts movies have carried all the wrong lessons forward. Placing spectacle and lore-building ahead of characters and story never works. Neither does relying on audience goodwill.
Apocalypse is one of the strongest beings on the planet. He has been shown to be powerful enough to trade blows with heavy hitters such as Hulk and the Juggernaut. While his base level strength is already at unprecedented levels, Apocalypse also has the ability to augment it.
Ban has superhuman strength and reflexes and, when he uses his Sacred Treasure, Courechouse, he can attain an even higher level than that. Despite this, if Ban were to go up against a fully powered Meliodas, he would definitely lose.
In terms of speed and physical strength, Superman and Black Adam are comparable. Superman possesses some additional abilities like his x-ray vision, his ice breath, and his eye-projected heat rays, but Shazam has some tricks of his own with his lightning powers and magical aptitude.
