It's debatable. There are many strong fictional characters, and it depends on various factors like powers, abilities, and the context of their stories.
It was difficult to have a definite answer for the strongest character in the history of anime because everyone had a different definition of the strongest. But there are some anime characters that are widely regarded as the strongest. These characters usually have amazing strength, skills, and wisdom.
Here are some of the characters that are considered the strongest in the history of anime:
1 Sun Wukong (Go Legend Gokū)-Dragon Ball
2 Ultraman-Ultraman
3 Sengoku-Dragon Ball
4. Lelouch of the Legit (The Rebellion of Lelouch)
5 Naruto Uzumaki-Naruto
6. Amagasaki Ichigo (One Piece)-Sea King
Of course, this was only a part of it. There were many other characters that were also considered very strong.
Well, deciding the strongest anime character is quite tricky. Different anime have different power systems and rules. For example, in Naruto, characters like Naruto and Sasuke are incredibly powerful, but it's not straightforward to compare them to characters from other series. It really comes down to personal opinion and the specific criteria you use to define'strongest'.
In general, it's a bit of a toss-up. The strength of Manga Goku and Anime Goku can vary depending on the specific arcs and battles. Sometimes, it might seem like one is stronger in a particular situation, but that could change in another.
I think Zeno would be a really tough opponent. Zeno has the power to erase entire universes, and a Goku and Goku Black fusion, despite being extremely powerful, would have a hard time against such a being with god - like powers.
Goku's ultimate form in the manga is Ultra Instinct. This state grants him enhanced combat abilities and reflexes. It's a breakthrough that showcases his potential and is a key factor in his toughest battles.
It's really hard to say. Goku has the power to destroy planets and reach incredible levels of strength with his Super Saiyan forms. However, Naruto has the power of the tailed beasts and his own sage mode which gives him a huge boost in power. And Sonic, while he may not have the raw power like the other two in terms of destruction, his speed is so great that he could potentially outmaneuver both of them. So it really depends on the situation and how the author writes it.
