While wearing his outfit, Joker also ties his hair back.

Personality
Joker is a mischievous man who works behind the scenes to accomplish his goals. He values the pursuit of truth above all else, believing that truth is only valuable form of justice and that he should abandon all restraints to find it. In his past, Joker had a desire to understand the world and become stronger, believing the Sun God would guide him. He abandoned this faith once he came to believe the world as a terrible place, becoming more cynical and relaxed as a result.

Shown to be very sneaky and intelligent, he always tries to play the cards his own way, going as far as involving innocent people in his schemes. Joker can be manipulative in the sense that he will use other people's interests as a way of unconsciously leading them to where he wants. Most notably when it comes to Shinra Kusakabe, during their conversations Joker seemingly  speaks with sincerity especially when discussing the fate of Shinra's mother. In some respects, Joker is lackadaisical and can get caught up in the moment, where he forgets his original goal. He is considerably a sadistic individual who enjoys hurting people and toying with their emotions. He's also willing to offer information to his opponents, in exchange for entertainment. He is charismatic and knows how to sway people to join his cause. Joker also has high expectations for Shinra and wants him to become a "Devil" to uncover the truth of his past, potentially hidden by the Special Fire Force.

In his youth, he also displayed skill with a knife, being able to quickly overpower larger opponents with ease. These combat skills are enhanced by his strength, as Joker is able to knock a trained combatant to the ground with a single punch and was able to use his tongue to push himself up from the ground. Joker is also fast, capable of catching up to Shinra, who was using his ability to accelerate himself. He also shows sharp observational skills as, In the midst of battle, Joker was able to notice movement as simple as change in trajectory

Ignition Ability
Joker has adapted to Spontaneous Human Combustion and become a Third Generation pryokenetic, granting him the ability to create and manipulate flames. Igniting his cigarette with his finger, he can create various shapes in the form of letters, suit of cards or card-shaped projectiles that can cut an inflammable coat. He is also capable of using his Ignition ability with a deck of cards, allowing Joker to parry to sword swigs and block attacks and quickly cut through human bodies.

Weapons
Twined with his Ignition ability, Joker is able to use an explosive powder crafted from Infernal ashes. This powder can instantaneously cause explosions or burst things into flames at command, as an offensive maneuver or for a trap. Joker uses a carton of cigarettes to ensure he always has a flame to control, the smoke created by these cigarettes has hallucinogenic properties that can cause his foe's to see multiple images of Joker.
