Very few manga series can compete with JoJo'sBizzareAdventure in terms of popularity. Over the years, the series has given the viewers many great characters to enjoy. However, not every character is a fan favorite and some of them are extremely despised by the readers.
These characters earn a bad reputation because of their wicked personality. They are very evil and have committed outrageous acts, which is enough for any normal person to detest them and in this list, we will take a look at the most nefarious characters in JoJo's Bizarre Adventure.
10 Kenzou
While he looked like a harmless, old man, Kenzou was one of the most ignoble individuals in the entire series. Kenzou used to be the leader of a cult, and one day, he and the other thirty-four members of the cult decided to commit suicide, but Kenzou drugged them and set the house on fire. Furthermore, Kenzou's idea of healthy is very questionable as he considers drinking his urine a health tip.
9 Thunder McQueen
Thunder McQueen is a minor antagonist who appears in StoneOcean. He was severely depressed and annoyed Ermes a lot. McQueen took his interactions with women very seriously and if he felt that things weren't going well, he would curse everything and try to kill himself. When he received a Stand from Pucci, he nearly killed Ermes several times, however, she saved herself with her quick thinking.
8 Yukako
Her appearance was enough to fool the characters as well the fans. She appeared to be a sweet and kind girl, who just wanted to be with Koichi, but over time, her true nature was revealed.
In reality, she was very freaky and obsessed with Koichi, who did not even love her at first. She stalked him and went as far as to kidnap him. She tortured him, but thankfully Koichi was rescued by Josuke and co. Yukako's methods were very questionable and without a doubt, she was one of the creepiest characters in the series.
7 Alessi
Alessi was an assassin sent by DIO to defeat the Joestar group, but like all the other ones, he failed as well. He was an extremely sick individual, who took pleasure in attacking women and children. Due to his cowardice, he only picked on people who were weaker than him. Alessi justified his immoral actions in his mind by being very irrational.
6 Steely Dan
Steely Dan is one of the few JoJo characters whose appearance left the fans infuriated. Once he took Joseph hostage he made Jotaro go through a lot of horrible things. He used Jotaro as a bridge, and he also hurt children.
He was very vulgar and on top of it, he was an utter coward. Steely Dan took out his frustrations on others and Jotaro quite rightly gave him a beating that put him out of commission.
5 J. Geil
J. Geil was a minor antagonist in StardustCrusaders. He was the son of Enya and like his mother, he served DIO and was sent to kill the Joestar group. A notorious murderer and a predator, J. Geil was responsible for the death of Polnareff's sister and sexual assaults on countless other women.
J. Giel was delusional enough to believe that all his victims were in love with him. He was an evil monster, who left many women in a complete mess. He was eventually defeated by Polnareff.
4 Angelo
He was one of the worst-known criminals in the series. When he was still a teenager, he killed three boys and was sentenced to death. He managed to survive his execution and ended up escaping from the prison.
Once outside, he began to commit crimes with the help of his newly awakened Stand. Angelo's disgusting behavior undoubtedly caused pain to several people and he felt no regret about his actions whatsoever.
3 Secco
Originally, Secco was one of Cioccolata's many victims, but after some time he became the latter's assistant. Secco would film all the atrocities that Cioccolata would commit. The two joined Passione, but Diavolo tried to never use them because he knew how dangerous they were.
2 Cioccolata
From a young age, Cioccolata showed his evil side. He was excellent at his studies, and he was destined for great things. However, Cioccolata had other things in mind. He volunteered to take care of sick, old people, but in reality, he gave them drugs that had been forbidden by law. He would also ruin their mental health to the point where many of them committed suicide. Cioccolata would also film the expressions of his victims.
Cioccolata went on to become a surgeon and he began to misdiagnose patients. He performed unnecessary surgeries and would give his patients the wrong doses of anesthesia so that they would wake up midway during the surgery. To make things worse, Cioccolata possessed one of the most overpowered Stands in the series.
1 Kira Yoshikage
While he may not want world domination, Kira Yoshikage is easily one of the most detestable characters in the series. He is the main villain of DiamondisUnbreakable and he was responsible for causing multiple deaths in Morioh.
Kira's Killer Queen allowed him to kill people silently, which is why his identity was hidden for such a long time. Kira was a sordid individual, who would kill women for their hands. In addition to this, he also killed other people, who tried to get in his way.
