Yoshikage Kira/Games

All-Star Battle (PS3)
Like many others, Kira makes his gaming debut in the PS3 title, playable as two distinct characters: His original form, with Killer Queen and Sheer Heart Attack; and his awakened form, with Killer Queen, Stray Cat, and Bites the Dust. This marks him as one of the only three characters with two incarnations, the others being Dio Brando and Joseph Joestar. Both versions of Kira are voiced by Rikiya Koyama, who previously voiced William Anthonio Zeppeli once in the Phantom Blood game.

Both Kiras are part of the mass majority of playable characters in the game with the "Stand" Style, being able to turn Killer Queen on/off, changing movesets, and having access to the Stand Rush ability returning from the Capcom game, being able to attack in conjunction with their Stand.

If Yoshikage Kira battles "Kosaku Kawajiri", they will have a special dialogue before the fight, where the original Kira will remark how 'Kosaku'-Kira's aura is similar to his, and 'Kosaku'-Kira will be shocked to see his past self. If the original Kira wins, he remarks that only he should be making bombs. If 'Kosaku'-Kira wins, he wonders if the encounter was an after-effect of "Bites The Dust".

Yoshikage Kira
Kira's original form appears as a DLC character included with pre-orders and first edition prints of the original Japanese release of the game. For the overseas release in the US, pre-ordering the game from Club Namco would also get players a free download code for Kira, whilst for EU players, pre-ordering the game from any retailer in that region would get the player both Kira and Shigekiyo Yangu as well.

Kira's moveset primarily involves Killer Queen, and the use of bombs and careful detonation. Killer Queen can perform a fist barrage like most other Stands, and as a result, can trigger a Stand Rush as well. One special move has Kira toss a coin into the air. The coin will explode if the opponent touches it or if Kira detonates it himself. Kira can also prime the opponent themselves as well, detonating them (similar to how he killed Shigekiyo Yangu). A close range detonation will damage Kira as well, however.

Kira's HHA has him swipe his and Killer Queen's arms downward. If they hit, Kira explodes his victim multiple times through Killer Queen's gestures while he adjusts his tie, unfazed.

His GHA is Sheer Heart Attack, which continues to chase the opponent until Kira's HH gauge completely empties or he is hit. If SHA connects, it will ram and drill into the opponent, knock them into the air, leap, and drop on them, exploding at point-blank range while Kira brags about Sheer Heart Attack lacking weaknesses/weakpoints.

Sheer Heart Attack can be temporarily slowed down by Koichi Hirose if the latter uses his "S.H.I.T" special or HHA on it, which will also subsequently affect Kira himself. It continues to be unblockable, but tends to be rather slow on the move.

Kira's alternate costume mirrors his casual outfit and hairstyle from his debut chapter.

"Kosaku Kawajiri"
'Kosaku'-Kira is included in the base game as the main antagonist of Part 4. In game, he is consistently labelled "Kosaku Kawajiri" to differentiate him from his previous form.

Along with Enrico Pucci, Hol Horse, Johnny Joestar, Koichi Hirose and Giorno Giovanna, Kosaku is a character who can utilize more than one Stand during a match as part of his moveset.

He retains Killer Queen in this form, whilst now having Stray Cat assist him throughout. While Killer Queen is off: While Killer Queen is on:
 * Ignition: Detonates whatever bomb may be out at the moment. Kosaku is at risk of taking damage if he is too close to the explosion. (Comboable)
 * Throw - "Can I ask your name?": Kosaku grabs the opponent explodes them in his hand.
 * Impact Igniton Bomb: Summons Killer Queen to fire an air bomb that must be manually detonated.
 * Trajectory change: Kosaku can correct the trajectory of the air bomb to face the opponent should they have dodged it, though it shrinks by one level. A Heavy bomb's trajectory can be changed up to four times.
 * I'll have to fight it out!: Summons Killer Queen to rush forward in a barrage of punches, knocking the opponent down. (Comboable through Puttsun Cancel)
 * I'll crush you!: Can only be used when the opponent is down. Killer Queen stomps on them.
 * Contact Bomb: Killer Queen fires an air bomb that can explode on touch. A Stand Rush skill that Kosaku can disconnect from to attack the opponent while it is executing. (Comboable through Puttsun Cancel)

His HHA, "Stray Cat's protecting me now!", is a counter/reversal. Killer Queen readies Stray Cat as Kosaku is shocked at it protecting him. If Killer Queen is struck during this pose, the opponent will be knocked back off their feet. Kosaku will use that chance to send out a completely invisible airbomb towards the opponent as they're getting up. Using his math knowledge, Kosaku correctly predicts where the air bomb is and detonates it, blowing up his opponent.
 * The First Bomb!: Killer Queen charges energy before chopping downward. If the opponent is it, they become a bomb themselves. Kosaku can detonate the opponent at any time, no matter what state they're in. A Stand Rush skill that Kosaku can disconnect from to attack the opponent while it is executing. (Comboable through Puttsun Cancel)
 * This stone is a bomb!: Killer Queen leaves a stone on the ground that must be manually detonated.
 * Air Bomb Cushion: Kosaku is protected from the next middle/high attack by a cushion. If Kosaku is hit with a low attack or turns Killer Queen off, the cushion is wasted.

His GHA is "Bite the Dust". Kosaku tosses out Hayato and forces him to run in fear. If Hayato runs into the opponent, they will be stunned by his sudden interference as Hayato panics, only to see Killer Queen, who enters their left eye and promptly detonates its Bites the Dust bomb, rewinding time. This adds 10 counts to the battle timer and restores Kosaku's health. Like with Sheer Heart Attack, Bites the Dust is unblockable, but is easily dodged/sidestepped/jumped over.

Bites the Dust, due to its time-rewinding ability, is able to reverse a number of character effects (especially round-lasting transformations). Thus, if Kosaku uses his GHA on Pucci with Made in Heaven, Giorno with Gold Experience Requiem, or Kars as the Ultimate Life Form, all three characters will revert back to their previous, normal forms. If the victim is MIH-mode Pucci, the stage will revert back to what it was previously. If Jonathan Joestar or Funny Valentine used their healing/comeback moves and disabled their Heart Heat Gauge as a result, said gauge will be restored once Kosaku executes his GHA successfully.

Kosaku's alternate costume mirrors his previous look before receiving the third bomb, with a spiky hairstyle and no coat.

Yoshikage Kira
Yoshikage Kira was confirmed for the game alongside Akira Otoishi, Shigekiyo Yangu. Most of his moveset was reused from the previous game.

His GHA has both him and Killer Queen strike a downed opponent, before Kira takes a step back and detonates them.

Tournament
He is paired with Old Joseph Joestar in the Eyes of Heaven tournament, defeating Josuke and Johnny Joestar in the first round. They were eliminated by Bruno Buccellati and Trish Una in the second round, who beforehand, won the F Block series of battles that allowed them to be matched against Kira and Old Joseph within the main tournament.

"Kosaku Kawajiri"
'Kosaku'-Kira was confirmed for the game along with Rohan and Okuyasu.

His GHA is similar to Bites the Dust's ASB variation, rewinding the battle timer and granting him health, but now heals his partner and the enemy not on the receiving end of the GHA as well.

Tournament
He is paired with Weather Report in the Eyes of Heaven tournament, defeating Akira Otoishi and Enrico Pucci in the first round, but eliminated by Giorno Giovanna and Guido Mista in the second.

Trivia

 * According to Kira himself, the total amount of women he's killed for their hands is 48.
 * He committed his first murder on August 13, 1983, around the age of 18.
 * According to a Top 10 List published in Weekly Shonen Jump in 2000, Kira is Araki's favorite antagonist and 2nd favorite character overall.
 * In an ironic twist, Kira has his hands severed multiple times: His left hand twice (when he removed Sheer Heart Attack from his body and when the Cleansers attacked him) and his right hand once (when he was bitten by Arnold in Reimi's alley as a ghost).
 * Kira's favorite fashion brand is Gianfranco Ferré.
 * The story of Kira's first murder as told by the ghost of Reimi Sugimoto shares similarities with the "Humans Can Lick Too" horror story.
 * Despite being the main antagonist, Kira doesn't have an active role in Diamond is Unbreakable until halfway in the part. The anime attempts to build up Kira's presence before his first appearance by showing the aftermath of his murders and the severed hands he's collected along the way, along with a quick cameo in episode 86.
