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. While Killer Queen is off:
 * Only one bomb at a time: A gameplay rule. Killer Queen may not have more than one bomb out at a time, automatically nullifying the previous bomb if another is used afterward.
 * Blown to pieces!: This skill can only be used following abilities marked with a star. Kira detonates whatever bomb may be out at the moment. All of Kira's bombs cannot be blocked, but Kira himself is at risk of taking damage if he is too close to the explosion.
 * Throw - Show you how it's done: Kira grabs the opponent by the neck and slams them into the ground, before stomping on their head.
 * It's your fate to be defeated: Killer Queen stomps on the opponent. This move can hit a downed opponent, and Kira's abilities may be performed instantly following the attack. (Comboable)

While Killer Queen is on:
 * Anything can be a bomb: Killer Queen takes out a small coin, turns it into a bomb, and flicks it into the air. Depending on the attack button inputted, the range of the coin as well as its explosive power is increased. This move is marked with a star, and while the coin will explode as soon as the opponent touches it, it can be manually detonated to catch them in the blast if they are close enough. (Comboable)
 * Ha!: Kira summons Killer Queen to rush forward in a barrage of punches, pushing the opponent away and knocking them down. This move cannot activate Rush Mode, and a similar ability by certain opponents will easily overpower Killer Queen. (Comboable through Puttsun Cancel)
 * Here's the first bomb: Killer Queen channels its power into its index finger, before both it and Kira chop downward. If the opponent is hit, they become a bomb themselves. This move is marked with a star, and Kira can detonate the opponent at any time, dealing heavy damage. For some reason, however, the explosion does not register if the opponent is down, wasting the attack. A Stand Rush skill that Kira can disconnect from to attack or move away from the opponent while it is executing. (Comboable through Puttsun Cancel)
 * You bastard!: Killer Queen unleashes a barrage of punches on the spot, knocking the opponent off their feet. This move cannot activate Rush Mode, and a similar ability by certain opponents will easily overpower Killer Queen. A Stand Rush skill that Kira can disconnect from to attack the opponent while it is executing. (Comboable through Puttsun Cancel)
 * Calm and cool: Killer Queen strikes a defensive stance, moving its hands rapidly around its face. If the opponent hits Kira with a non-Throw/HHA/GHA physical attack, Killer Queen counters with a punch that sends them flying.

Kira's HHA, "I'm going to blow you to smithereens!", has him swipe his and Killer Queen's arms downward. If they hit, Kira explodes his victim six times through Killer Queen's gestures. After the fifth explosion, Kira looks away to adjust his tie shortly before the sixth explosion occurs, being the most powerful.

Kira's GHA, "Sheer Heart Attack", sends out Killer Queen's secondary bomb; Sheer Heart Attack. SHA cannot be blocked and follows the opponent until it connects, flies off-screen if dodged, or Kira is hit. If SHA connects, it will ram and drill into the opponent's abdomen, knock them into the air in an uppercutting leap, and drop on them. Yelling at the opponent to look at it, Sheer Heart Attack explodes in their face at point-blank range, while Kira brags about it lacking weaknesses/weak points.

Sheer Heart Attack can be temporarily slowed by Koichi Hirose if the latter uses ACT3's "S-H-I-T" move or "Echoes ACT3: FREEZE!!" HHA on it, which will also subsequently affect Kira himself. SHA continues to be unblockable and able to hit him, but will continue to be sluggish until Koichi gets a certain distance away from it or hits Kira, nullifying the bomb altogether.

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, but now possesses Stray Cat to assist him in battle. While Killer Queen is off: While Killer Queen is on:
 * Only one bomb at a time: A gameplay rule effect continued from the original Kira. Killer Queen may not have more than one bomb out at a time, automatically nullifying the previous bomb if another is used afterward.
 * Ignition: Kosaku detonates whatever bomb may be out at the moment. All of Kosaku's bombs cannot be blocked, but Kosaku himself 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 as he throws them.
 * Impact Igniton Bomb: Kosaku summons Killer Queen to utilize Stray Cat and fire an air bomb that must be manually detonated. These bombs deal more damage than Contact Bombs, and cannot be jumped over during their explosion. However, Kosaku cannot move when this bomb is out, and the bomb disappears as soon as he is hit.
 * Trajectory change: Kosaku, using his math skills, can correct the trajectory of the air bomb should the opponent have dodged or jumped over it, in order to once more send it in their direction. This increases the speed of the air bomb but shrinks it by one level. A Light bomb's trajectory can be changed only once, while a Heavy bomb's trajectory can be changed up to three times.
 * I'll have to fight it out!: Kosaku summons Killer Queen to rush forward in a barrage of punches, pushing the opponent away and knocking them down. This move cannot activate Rush Mode, and a similar ability by certain opponents will easily overpower Killer Queen. (Comboable through Puttsun Cancel)
 * I'll crush you!: This move 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 automatically. The bomb is able to disarm traps, though is popped by all projectiles aside from another Kosaku's own Contact Bomb. When the bomb is launched, Kosaku may move after a short delay (Comboable). A Stand Rush skill that Kosaku can disconnect from to attack the opponent or move away from them or the bomb while it is executing. Killer Queen can still be caught in the explosion if Kosaku uses Stand Rush in attempts to escape the blast. (Comboable through Puttsun Cancel)

Kosaku's 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 in this form with a non-Throw/HHA/GHA, the opponent will be knocked back off their feet and onto the ground. Kosaku will use that chance to send out a completely invisible air bomb towards them 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 channels its power into its index finger before chopping downward. If the opponent is hit, they become a bomb themselves. Kosaku can detonate the opponent at any time, no matter what state they're in, dealing heavy damage. A Stand Rush skill that Kosaku can disconnect from to attack or move away from the opponent while it is executing. (Comboable through Puttsun Cancel)
 * This stone is a bomb!: Killer Queen leaves a stone primed with the first bomb on the ground that must be manually detonated. If the opponent is hit, they are sent flying far away from Kosaku if hit, giving him more room to unleash air bombs.
 * Air Bomb Cushion: Kosaku is protected from the next middle/high physical attack by an air cushion placed in his suit by Stray Cat, pushing the opponent away if they trigger it. If Kosaku is hit with a low attack or turns Killer Queen off, the cushion is nullified.

Kosaku's GHA is "Bites 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 he panics, only for them to see Killer Queen, who enters their left eye and promptly detonates its third bomb, rewinding time. Surprisingly, this GHA deals less damage than most, doing only 21% of the opponent's health in damage, making it inferior even to his HHA. Like with Sheer Heart Attack, Bites the Dust is unblockable, but is easily dodged/sidestepped/jumped over, and Hayato will only run a short distance in front of Kosaku before sprinting the other way. These two factors make Kosaku's GHA the easiest to avoid in the entire game. However, if successful, the GHA adds 10 counts to the battle timer and restores 15% of Kosaku's health. When in Rumble Mode, instead of calling out the bomb's name, Kosaku will yell "This is the limit! Push it!", and the GHA will deal substantially more damage.

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 the GHA on Pucci in Made in Heaven Mode, Giorno with Gold Experience in Requiem Mode, 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, and Pucci will never be able to enter MiH Mode for the rest of the entire battle as per his own gameplay rules. If Jonathan Joestar or Funny Valentine used their healing/comeback moves ("This is my final Ripple!" and "Back from the 'other side'", respectively) 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 changed, as Sheer Heart Attack is now part of his regular arsenal. Both Kira and Killer Queen strike a downed opponent, before Kira takes a step back and detonates them in a single massive explosion.

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, whom 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 opponent that is 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 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 from the very first episode of the Part 4 anime, along with a quick cameo in episode 86.
