Greatest anime arcs with polt twists

I tried compiling a list of the greatest anime arcs. Here are a few I’ve watched:

1. Marineford arc in One Piece (along with Dressrosa, Wano, and Enies Lobby)
2. Chimera Ant arc in Hunter x Hunter
3. Frieza Saga in Dragon Ball
4. Infinity Castle arc in Demon Slayer: Kimetsu no Yaiba
5. Return to Shiganshina arc in Attack on Titan

There are plenty more, but they are the ones that come to mind. And in my opinion, the best arcs in anime.

Especially plot twists.
