There are many characters to choose from that developed really well in my opinion but I’m going to list the top characters that I think are the most developed.
Inuyasha
- Inuyasha - his character goes through some of the biggest emotional developments I’ve see in a really long time. Kagome brings out the good side that Inuyasha locked away due to the fact that his first love sealed with a special arrow. There are so many changes he goes through that it would take forever to list them. The show ran for 7 seasons!
Nura: Rise of the Yokai clan
- Rikuo Nura - this was a two season show. Rikuo is only 12 years old in the series but he is the half-demon child of Nura clan. His grandfather passed away making him the new leader of the clan. You watch Rikuo have to grow up very quickly due to being the next head of the clan. He goes from grieving child to a mature young man over the course of the two seasons. On top of that, he actually starts a relationship with the girl he likes as well. There are multiple different depths to this show.
Naruto and Naruto Shippuden
-
Naruto Uzumaki - hands down Naruto is one of the best Developed characters in anime history. You watch him.grow up into.adult hood. He starts off as trickster who is hated because of what is inside him then he grows into a young man who has finally made a family with the people of his home. He has an ability to motivate others into standing with him during a fight which is what meld his bonds with his closes friends. He ends losing one friend but never stops looking for him to redeem himself and complete his family again. He loses many people he cares about through the show which does take it’s toll but those around him helped him get back on his feet again.
-
Sasuke Uchiha - he is another very good developed character. His whole clan was killed by his older brother who Sasuke vowed to kill if he ever saw him again. The sad truth of massacre is brought to the surface in a much later part of the series. He goes from being a child that has only hate for his brother which led to the revenge engulfing his good side completely. He goes dark which leads him to make friends with the wrong people so that he can become stronger. This makes him vow revenge on his former home after he abandoned it. It takes most of the show for Sasuke to realize the truth and to accept his home and family again .
