Ken Kaneki/Haise Sasaki (Tokyo Ghoul)

Ken Kaneki is the main protagonist of the dark manga series Tokyo Ghoul, and its sequel, Tokyo Ghoul:re. He is currently the husband of Touka Kirishima, the father of Ichika Kaneki, and the best friend of Hide Nagachika.

Why He Rocks
2. Both Natsuki Hanae (Japanese) and Austin Tindle (English) did an amazing performance voicing him.
 * 1) His personality changes after being haunted and traumatized is not only interesting, but also sad as well.
 * Human Kaneki: A shy college student who just want to read books.
 * White hair Kaneki: After being tortured by the infamous Jason, he accepts his ghoul side and became cold hearted.
 * Haise Sasaki: Suffering from amnesia, he is working with the enemy of ghouls. Haise may have his dorky side, but he is actually a reliable mentor. While funny, yet he is haunted by his former self.
 * Black Reaper: After getting his memories back, not only is he more cold hearted than his former self, but he is suffering from depression. Which is understandable, because he lost his mother at a very young age. He will do anything to die to protect his friends.
 * One Eyed King: He gained a new personality where he will stay alive to protect his friends and loved ones. He needs to be king in order to make peace between humans and ghouls.

3. Amazing character design.

4. He doesn't hesitate to help anyone whenever they are hurt. For example, Nishiki being beaten up by one of the thieves, he helps him. Despite the fact that both Kaneki and Hide were treated harshly by Nishiki.

5. He gets accepted by people who share a similar backstory with him. Including his own enemies, Kishou Arima and Eto Yoshimura. Which is why he is much stronger than before.

Bad Qualities

 * 1) While likable, he isn't properly protrayed in the anime. In the manga, he is traumatized, yet he is living happily with Hinami, Tsukiyama, and Banjou. However in Season 2, he is nothing but a sad, yet vengeful young man. Making him having the same personality as Jotaro Kujo from JoJo's Bizzare Adventure.
 * 2) Due to :re Season 2's rushed pacing, he is sadly underdeveloped.
