who is the strongest character in the big 3 of anime?

The "Big 3" of anime typically refer to the most popular and influential long-running anime series: "One Piece," "Naruto," and "Bleach." Determining the strongest character among them is subjective and can lead to debates among fans. However, here are a few contenders:

1. "One Piece": Monkey D. Luffy possesses immense physical strength, adaptable powers (via his Devil Fruit, Gomu Gomu no Mi), and strong willpower, making him a formidable opponent.

2. "Naruto": Naruto Uzumaki, the main protagonist, is a ninja with the Nine-Tails sealed within him. He possesses incredible chakra, powerful jutsus, and ultimately becomes the strongest ninja in the series.

3. "Bleach": Ichigo Kurosaki is a Soul Reaper with the power to manipulate spiritual energy and transform into various forms. His strength grows consistently throughout the series, allowing him to defeat numerous powerful foes.

However, it's important to note that power levels may change throughout the respective series, and multiple characters from each show could also be considered contenders for the title of the strongest.
