Personality
Mukuro is often seen with a playful smile and seems apathetic to the suffering of others. Appearing as the series' first antagonist, Mukuro is not averse to disposing of those who get in his way, and is not easily intimidated, usually speaking to others in a very direct and arrogant manner. Prior to his first appearance, he, along with Ken Joshima and Chikusa Kakimoto, is mentioned to have been locked up in a high security Italian prison, which is reserved for the most dangerous of Mafia criminals, who have even committed crimes against the Mafia itself. He cares little for others, and simply considers people to be "toys" he can sacrifice in order to get to what he wants. However, despite claiming this, he tolerates both Ken and Chikusa, and even protects them, as well as sacrifice himself for them, when need be, though does not do so in front of them. He also seems to care for Chrome, though hides it in front of others. To keep his identity hidden, Mukuro periodically controls several people, most notably Lancia, whom he uses as a "fake Mukuro".

Mukuro have a strong resentment for the entire Mafia underground, most likely due in part to the experimentations he suffered as a child at the hands of the Estraneo Mafia family. When Mukuro killed his captors, he offered Chikusa and Ken, who were also victims of experimentation, a chance to join him in his quest to destroy the world. However, not only does he want to take revenge on the Mafia by destroying it, he also wants to cleanse the world of its filth by invoking universal suffering through a world war. Even after becoming the Vongola's Mist Guardian, Mukuro still claims to no longer be part of the Mafia, having been exiled from it, and continues to view the organization with great contempt.

Weapons and abilities
Known as someone who has driven both the Mafia and police into dangerous and desperate of situations, Mukuro is a deadly opponent. Though Mukuro's main weapon is a trident, and is capable of using combative skills, he is first and foremost a master of illusions, thus he is not easily deceived by illusions that are cast by others. His abilities lie in his "Six Paths of Rebirth" (六道輪廻), six different skills which he claims has been carved into his memories by having had his body go through all six paths to Hades. When using his skills, a Japanese numeral, corresponding to the realm he has entered, appears in his right eye. The skills granted from the individual paths varies from enhancing his physical and mind-controlling abilities, as well as his power of his illusions, to enabling him to control and summon animals.

Mukuro also possesses the Estraneo Family's Possession Bullet, a forbidden bullet which enables a person to possess the body of another person when the possessor is shot with it. With this, Mukuro is able to possess and control the body of anyone that he has cut with his trident. He can possess several bodies simultaneously, and he is also still able to enter the Six Realms, granting him the ability to use a different skill for each body.

In Reborn!
After arriving in Japan from Italy, and enrolling in Kokuyo Middle School, ten days prior to their first appearance, Mukuro, Chikusa, and Ken, started a gang made up of Mafia criminals, and began their quest to find the Vongola's tenth generation boss. After having his subordinates attack the strongest students in Namimori Middle School, he successfully draws out the tenth boss, Tsunayoshi Sawada. During Mukuro's fight with Tsuna, he reveals his plans of taking over Tsuna's body in order to take revenge on the Mafia. However, he loses the battle to Tsuna and he and his friends are imprisoned by the Mafia's guardians, the Vendicare.

They later attempt a breakout, but Mukuro uses himself as bait, and ends up being thrown into the lowest level jail cell. Whilst strolling in his illusions, he comes upon Chrome Dokuro, who was on the verge of death, and possesses her, saving her life with illusionary organs. He then makes a bargain with the Vongola to become one of the ring guardians in exchange for Ken and Chikusa's safety. Now sharing an existence with Chrome, Mukuro later helps her defeat Mammon after he emerges in his own form.

In the story's alternate future, Millefiore member Glo Xinia gloats about having defeated him to a displaced Chrome, who had been transported into the future by the Ten-Year Bazooka. However, the future Mukuro had possessed Glo's owl and helps Chrome defeat him in battle. While spying on the Millefiore Family, Mukuro engages Byakuran in battle but is severely wounded. He reappears as an illusion during the Vongola's battle against Byakuran in order to give the Vongola enough time to escape. He is later able to assist them in person after his apprentice, Fran, frees his body from the Vendicare's Prison.

After Tsuna's group returns to the past, Mukuro is lured into possessing Chrome when Daemon Spade endangers her life. Mukuro seemingly defeats Demon, but the latter is able to take over Mukuro's imprisoned body before Mukuro's spirit can return to it and breaks out of prison to confront the group shortly after. He is later restored to his physical form after Tsuna defeats Demon and expel his spirit. As the Vindice acknowledge Mukuro's efforts in his fight with Demon, he is freed and returns to Kokuyo.

Several weeks after the battle with Demon, Mukuro leaves Chrome in Namimori. He finds and recruits Fran into the group. Verde requests for Mukuro and his gang to fight for him in upcoming Arcobaleno battle, which Mukuro accepted in order to fight Tsuna and his Family. During the first day of the Representative battle, Mukuro's team able to defeat five people within ten minutes, thanks to Verde's machine that able to change illusion into reality. At the second day of the Representative battle, he, and his team fight Tsuna's team and Byakuran's team. At the third day of the Representative Battle, he reluctantly formed temporary alliance with Team Reborn to defeat the Vindice. With Chrome's help, they unleashed a combined technique that defeated two Vindice with the last one defeated by Tsuna. After Tsuna's brief battle with Jager and knowing the truth about the Arcobaleno, he, along with the other remaining teams formed alliance with Tsuna as the core to defeat Team Bermuda. At the fourth day of Representative Battle, he, Dino, Squalo, Xanxus, Byakuran, and Hibari confronts Jager, preventing him from helping his teammates while Tsuna, Enma, and Basil defeats them one by one. Jager succeeded in defeating Dino, Squalo, Xanxus, and Byakuran, leaving only Mukuro and Hibari to fight until Tsuna arrived to help. Using his illusion, Mukuro trapped Jager while he's preoccupied with him and Hibari, giving Tsuna the opportunity to defeat the Vindice. His boss watch is then destroyed by Bermuda, disqualifying him.
