All-Star Battle/Kosaku Kawajiri

Kosaku Kawajiri (Yoshikage 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. Kosaku Kira has 1000 HP.

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 moves; He retains Killer Queen, but exchanges some powers like Sheer Heart Attack for access to Stray Cat, who assists him in battle with its air bubbles.

Gameplay Overview
Kosaku is a "zoner"-style character utilizing both Killer Queen and Stray Cat. With good normal attacks, a counter HHA, and his unblockable and versatile air bombs, he can make his opponent hesitant to attack. An individual air bomb creates large explosions inflicting devastating single-hit damage. Said explosions linger for considerable amount of time, and Kosaku can utilize this trait against an opponent recovering from knockdown, detonating air bombs over them as they get up to catch them in repeated unblockable explosions. Even when threatened by a close-ranged foe, he has abilities, such as Killer Queen's other bombs, that are useful for creating much-needed distance. Above all else, his unique GHA both replenishes his health and can potentially turn the tide of battle by undoing his opponent's passive abilities and powered-up states.

However, Kosaku is innately high-execution and high-risk. His most notable combos and offensive setplay involve closely following behind Contact Bombs that place him at risk of self-inflicted damage, even requiring he Stylish Evade his own explosions. Due to the relative predictability of air bombs, Stylish Evade is also his greatest weakness and opponents that can execute the ability consistently can trivialize their power. In addition, Kosaku struggles against fellow zoner types; Fast projectiles can interrupt Impact Ignition Bombs and pop Contact Bombs, ultimately forcing him to be the aggressor.

Kosaku is a technical character whose strange techniques belie a wealth of lethally powerful unblockable attacks, leading to constant high-damage and Heart Heat gain. Maintaining good spacing from the opponent to keep himself safe naturally grants him many opportunities to unleash his deadly bombs. When combined with multiple defensive and reversal abilities including Bites the Dust, Kosaku can quickly compound small advantages into assured victory.

Miscellaneous
If Kosaku is defeated by Okuyasu, he'll whisper to himself that luck was supposed to be on his side.

If Kosaku uses his GHA on Rohan, Rohan will scream Koichi's name as he blows up, referencing his temporary death.
