It's hard to say for sure. Deku has grown a lot, but All For One is a powerful villain. It depends on various factors like their current abilities and the circumstances of the battle.
It depends on personal preferences. Some people think it is the best because of its rich world-building and diverse characters. But others might have different favorites based on their own tastes.
The One Piece anime doesn't cover everything from the manga. There are instances where the anime slows down the plot or adds non-canon material. However, the core storylines and major events are mostly adapted accurately.
" Ten Thousand Swords Return to One " was a Launcher skill in Butterfly Blue's eSports novel," The Expert " and its derivative works.
This skill requires 10 seconds to be cast. When cast, Super Armor will be formed. After casting, 10 sword-shaped energy bodies will be formed around the Launcher. Each sword-shaped energy body can attack individually. The attack power of the sword-shaped energy body is related to the Launcher's attack power. The attack range of each sword-shaped energy body is 5 meters, and the attack range of 10 sword-shaped energy bodies is 50 meters. When using this skill, the Launcher can move, but their movement speed is halved.
Ten Thousand Swords Return to One was a Launcher's ultimate skill. It was powerful, but it took a long time to cast and was easily interrupted. In the novel, this skill was used many times by Ye Xiu's Launcher character, Lord Grim, and became one of his signature skills.
