Before stands, JoJo's Bizarre Adventure had a completely different power known as Hamon or Ripple. Hamon was the power system for two entire parts, namely, Phantom Blood and Battle Tendency, before being replaced by stands. The power relied on controlled respiration, so a person needs to undergo rigorous training in order to master Hamon.
Hamon is identical to the energy of the Sun and it is opposite to the energy that is produced by vampires and pillar-men. A lot of characters managed to train their Hamon. Here, we will be going through the five strongest Hamon users and five who are the weakest.
10 BEST: JONATHAN JOESTAR
Jonathan Joestar is the protagonist of the very first part. He grew up with his adoptive brother, Dio Brando. Jonathan was in a difficult situation when he found out about Dio's plan to get rid of George Joestar. Dio managed to kill George Joestar with help from a magical mask. Jonathan decided to beat Dio himself and was trained for it by Baron Zeppeli. His training finally paid off as he did manage to beat Dio by using Hamon.
9 WORST: LOGGINS
The unfortunate Loggins was the trainer of Joseph. He taught Joseph everything that he knew about Hamon, but he never got a chance to see the skills of his student because he was killed in a gruesome manner by Esidisi. Loggins' skill with the Hamon was unable to save him from Esidisi and his insane abilities.
8 BEST: KARS
Kars is the main antagonist of the Battle Tendency. He managed to achieve the status of the "perfect being." In his perfect form, Kars had an IQ of 400. Also, he could use Hamon in his ultimate form.
His Hamon was hundreds of times stronger than Joseph's and Stroheim actually compared it to the intensity of the sun. Kars could even trigger a volcanic eruption with his Hamon.
7 WORST: MESSINA
Messina was one of the two trainers who were employed in the service of Lisa Lisa. He was considered a master of Hamon as he was trusted with the very important job of training Caesar and Joseph. Messina had been training with Hamon for years, but he was surpassed by his student, Caesar within just three weeks. During the fight between Caesar and Messina, Caesar managed to burn the hair on the arms of the latter.
6 BEST: JOSEPH JOESTAR
Considered by many fans as the best JoJo in the series, Joseph Joestar is a Hamon master. From a young age, Joseph showed that he had some skill with Hamon especially when he managed to beat Santana without proper training. However, it wasn't until he went to Venice that his skills were properly developed. The arduous training that Lisa Lisa put him through helped him greatly and it allowed him to beat Wamuu, Esidisi, and Kars.
5 WORST: STRAIZO
Straizo was one of Tonpetty's followers and he aided Jonathan Joestar in his fight versus Dio Brando. He was skilled in the ways of Hamon and replaced Tonpetty as the head of their order. However, Straizo was scared of growing old, and this led to him betraying his order.
Straizo became a vampire, who knew how to use Hamon. This should have made him unbeatable, however, many theories suggest that Strazio's Hamon became weaker after he became a vampire.
4 BEST: CAESAR ZEPPELI
Next up on the list is the charming Caesar Zeppeli. He is one of the main characters in Battle Tendency. Caesar had been training under Lisa Lisa in order to gain better control over his Hamon. When Joseph arrived in Venice, the two of them trained rigorously to improve their Hamon. Caesar managed to surpass his trainer, Messina in a very short period. Also, he is capable of channeling Hamon through objects.
3 WORST: TONPETTY
Tonpetty was the teacher of Straizo, Dire, and Baron Zeppeli. He was the leader of his order before Straizo replaced him. Tonpetty had the ability to predict the future of a person just by touching their hands. Tonpetty never showed any extraordinary fighting abilities, but his hamon enabled him to heal others, a skill that he passed onto his disciples.
2 BEST: LISA LISA
Lisa Lisa was raised by Straizo as his own daughter. She learned about Hamon from her father, and she excelled at using Hamon; she was anointed as the caretaker of the Red Stone of Aja. Lisa Lisa trained both Caesar and Joseph in order to improve their Hamon. Her Hamon was three times more powerful than Joseph's. She would have easily managed to beat Kars if he had decided to fight her fairly.
1 WORST: MARIO ZEPPELI
Mario Zeppeli is the not-so-nice father of Caesar Zeppeli. He left his family and they suffered a lot since they were all very young. Mario trained his Hamon for a long time and had teamed up with Lisa Lisa in order to fight against the Pillar Men. Mario was killed before he could ever display his skill with Hamon.
