There were many anime protagonists that had a very strong presence, but there were also some that had no presence at all. Here are some examples: 1. Xiao Li in Naruto: Although he is one of the main characters, his presence in the plot is not strong. Xiao Li was just a simple ninja. His existence was only to promote the development of the plot. 2. Monchi D. Luffy in One Piece: Although he was one of the main characters, his image in the plot was not very distinct. Luffy was an adventurous protagonist, but his presence was not strong. 3. The Night God Moon in the Death Note: Although this character is one of the main characters, his presence is very weak. Yagami was a genius high school student who used the Death Note to commit crimes, but his actions were not recognized by the people. 4. Altolia Pendragon in Fate/Zero: Although she was one of the main characters, her presence was very weak. Artolia was a young lady with the spirit of a Holy Knight. She existed only to complete her mission. 5. Alan Yaeger in Attack of the Giants: Although he was one of the main characters, his sense of existence was very weak. Alan was a young giant whose goal was to destroy the human race, but his actions were not recognized by the human race. Although these characters had a strong presence in some aspects, their performance in the plot was not very good, so their presence was relatively weak.
