Koichi Hirose (広瀬 康一, Hirose Kōichi) was confirmed to return for All-Star Battle R during the game's initial announcement trailer.[1]
His moveset is fundamentally the same as his from All-Star Battle, with a few tweaks being made to both balance the character and fit him into the overall gameplay changes that All-Star Battle R brought.
In the English localization of the game, the name of Koichi's Stand, Echoes, is localized as "Reverb", the same name used in the original All-Star Battle.
Yuki Kaji reprises his role from the Diamond is Unbreakable anime, replacing Romi Park. As with the majority of the game's roster, voice lines for Koichi were either added or re-recorded.
Koichi has 900 health and uses the Stand (スタンド, Sutando) Battle Style, which allows him to freely summon and withdraw his Stand Echoes, dynamically changing his moveset in the process.

ON GROUND
Switches between User Mode and Stand Mode. Doing so summons or dismisses Echoes ACT3, changing the skills Koichi has access to.
Stop it! (やめろォーーーッ)
+ ON GROUND
Koichi lunges forward and swings a fist with all his might. If the punch connects, the opponent crumples to the ground. A command normal that can chain into Koichi's skills. (Comboable)
Attack type: High Damage: 35
Rumble Mode (ゴゴゴモード)
Activates below 30% health
This mode is automatically activated once Koichi falls below 30% health. It increases his attack power, as well as the rate at which the Heart Heat Gauge rises, while also decreasing the rate at which the Guard Gauge drops.
Skills [Stand Off] (コマンド技)
I'll never forgive you! (ゆるさないぞ)
+ //ON GROUND
Koichi summons ACT1 to fly forward a moderate distance and assault the opponent with loud and disruptive sound effects. The distance ACT1 travels and the damage dealt increases in order, but the greater the increase, the more vulnerable Koichi becomes. This move has a follow-up. (Flash Cancel comboable)
"Ah, tranquility, seeping into rocky crag, a cicada's trill" (『閑かさや岩にしみ入る蝉の声』)
(When "I'll never forgive you!" hits) //ON GROUND
ACT1 increases the number and volume of its sounds, causing the opponent to take damage multiple times and crumple from the noise. (Comboable)
Attack type: High Damage: 2 × 5 + 5 (15)
Sizzle! (ドジュウウ)
+ //ON GROUND WHEN DOWNED
ACT2 throws its tail end as an arcing projectile sound effect. If it hits the opponent, they will take damage and catch fire, causing them to gradually lose health over time for a few seconds. If it misses, it will leave flames on the ground for a short period of time instead. The opponent will then catch fire if they touch these flames. The distance the projectile is thrown and the damage dealt by the initial hit increases in order, but the greater the increase, the more vulnerable Koichi becomes. The height the projectile is tossed also decreases in this order. This move functions as an anti-air and can hit downed opponents, dealing a small amount of damage to them and setting them on fire. (Flash Cancel comboable)
A counter. Koichi boldly crosses his arms and side-glares at the opponent. If they strike him during that moment, sound effects by ACT2 will reveal themselves on Koichi and produce a forceful explosion, blowing the opponent back. The damage dealt when activated increases in order, but the greater the increase, the more vulnerable Koichi becomes.
Attack type: Counter Damage: 100 / 120 / 140
Boing! (ボヨヨオ～ン)
+ //ON GROUND TRAP
ACT2 slaps a sound on the ground in front of Koichi as a trap. If the opponent comes in contact with it, they'll be blown upward into the air and land in a soft knockdown. The distance forward that ACT2 places the sound increases in order, but the greater the increase, the more vulnerable Koichi becomes. If Koichi himself steps on it, he will be sprung high into the air akin to a Super Jump ability, allowing him to evade many of the opponent's attacks or set up his own attacks from the air. (Comboable)
Attack type: Low
Normals [Stand On] (通常技)

Style/Specials/Etc. [Stand On] (スタイル/特殊技/その他)
Stand ON/OFF (スタンドＯＮ／ＯＦＦ)
ON GROUND
Switches between User Mode and Stand Mode. Doing so summons or dismisses Echoes ACT3, changing the skills Koichi has access to.
Rumble Mode (ゴゴゴモード)
Activates below 30% health
This mode is automatically activated once Koichi falls below 30% health. It increases his attack power, as well as the rate at which the Heart Heat Gauge rises, while also decreasing the rate at which the Guard Gauge drops.
Skills [Stand On] (コマンド技)
Hit them, ACT3! (くらわせろ『ＡＣＴ３』ッ！)
+ //ON GROUND
ACT3 flies forward a moderate distance while rapidly punching, pushing the opponent away. The distance ACT3 travels and the damage dealt increases in order, but the greater the increase, the more vulnerable Koichi becomes. (Flash Cancel comboable)
ACT3 rises upward and comes down, punching with the power of 3 Freeze active, knocking the opponent down. The distance forward ACT3 travels before delivering its downward barrage increases in order, but the greater the increase, the more vulnerable Koichi becomes. This skill functions as an anti-air, can strike a downed opponent, and inflicts 3 Freeze for a short duration. While under the effect of 3 Freeze, the opponent will be put in a gravitated state, preventing them from dashing in either direction, running, jumping, dodging, stylish guarding or dodging, Flash Canceling, or using skills, command normals, or Style actions (excluding Stand On/Off and Mounting). A Stand Rush skill that Koichi can disconnect from to freely act while it is executing. (Flash Cancel comboable)
Of note is that this skill will not lose its Middle-hitting property when Stand-Rushed, allowing Koichi himself to assail a defending opponent with crouching normals while ACT3 simultaneously attacks from above, resulting a high-low offense that is difficult to defend against.
(While taking damage or guarding) + for 2 HH ON GROUND
While being hit or guarding against attacks, ACT3 suddenly releases a potent burst of air that launches the opponent back. If the opponent is in the air when this skill is activated, instead of being pushed away, the opponent will instead be knocked to the ground. This is a combo-breaking skill that costs 2 stocks of the Heart Heat Gauge to use.
Attack type: Unblockable
Throw (投げ技)
Fwoosh! (ドヒュウウウ)
2 ATK buttons near opponent or ( to back-throw) ON GROUND
Koichi shoves the opponent off-balance while ACT2 whips them with a "Whooosh!" SFX from its tail, sending them flying in the desired direction.
Attack type: Throw Damage: 100
Heart Heat Attack / Great Heat Attack (ＨＨＡ / ＧＨＡ)
Echoes ACT3: Freeze! (必殺『エコーズ３ＦＲＥＥＺＥ！！』)
+ 2 ATK Buttons
ON GROUND
Koichi sends ACT3 flying forward a considerable distance, rapidly punching with the power of 3 Freeze active for an extended period of time. The opponent is pushed away, and the final hit will knock them down. Successfully landing the attack inflicts the 3 Freeze effect for about 5 seconds, preventing the opponent from dashing in either direction, running, jumping, dodging, stylish guarding or dodging, Flash Canceling, or using skills, command normals, or Style actions (excluding Stand On/Off and Mounting). This HHA does not require an initial hit to connect in order to work, and will not stop until it finishes or Koichi is interrupted. This HHA deals considerable Guard Gauge damage, dealing about half the Gauge, making it very easy for Koichi to get guard breaks if he so desires.
If this HHA hits Yoshikage Kira's GHA, Sheer Heart Attack, it will cause both it and Kira to be affected by 3 Freeze, causing SHA to slow down, use a unique voice line, and Kira to perform a special animation where he holds his hand while crouching.
Attack type: High Damage: 5 × 14 + 120 (190)
“
Echoes ACT3: Freeze! (必殺『エコーズ３ＦＲＥＥＺＥ！！』)
”
Does this mean I've gotten stronger?! (ひょっとして成長したんですかァ！？ ぼく！？)
+ 3 ATK Buttons or ON GROUND
Koichi first summons Echoes ACT1 to throw a "BAM!" sound projectile forward. If it connects, the opponent is assaulted by loudly-repeating booming sounds, forcing them to cover their ears. ACT2 then flies in and slaps a sound on the floor beneath the opponent, blasting them skyward. Finally, ACT3 appears above the airborne opponent and charges up 3 Freeze, before assaulting them with an intense barrage of punches. The final strike causes ACT3 to pass through the opponent, before they fall with increased gravity, smashing harshly into the ground.
This GHA inflicts the 3 Freeze effect for 5 seconds.
Due to how high ACT1 is when it throws the sound effect, this GHA will miss against crouching and short opponents when used point blank.
Attack type: High Damage: 318 / 381 / 477 (depending on HH gauge)
“
Come on Echoes! I got ya! Echoes ACT3: Freeze! (行けっ！ ぼくのエコーズ！ 必殺ッ！ 『エコーズ３ＦＲＥＥＺＥ』)
”
Assist System (アシストシステム)
Assault Assist (アサルトアシスト)
ON GROUND
A two-stock assist. Koichi lands in and summons Echoes ACT3 to rise into the air and come down, punching with the power of 3 Freeze active, knocking the opponent down and afflicting them with 3 Freeze, preventing them from dashing in either direction, running, jumping, dodging, stylish guarding or dodging, Flash Canceling, or using skills, command normals, or Style actions (excluding Stand ON/OFF and Mounting). Koichi then dismisses his Stand and poses before jumping back off-screen.
Attack type: Middle Damage: 91
Reversal Assist (リバーサルアシスト)
ON GROUND
A one-stock assist. Koichi jumps into the opponent while Echoes ACT3 punches them away. He then dismisses his Stand and poses before jumping back off-screen.
When hitting an aerial opponent, this attack no longer causes a soft knockdown, instead causing basic hitstun.
Style/Specials/Etc. [Stand Off] (スタイル/特殊技/その他)
Stop it!
+ ON GROUND
This command normal now causes a crumple instead of launching the opponent away. It is also now a High rather than a Middle. Furthermore, it executes faster now, making it slightly less reactable. It can also be canceled with Quick Stand on now.
Skills [Stand Off] (コマンド技)
I'll never forgive you!
+ //ON GROUND
Echoes ACT1 now travels much farther than it did in All-Star Battle for the and variants. Also, on hit, it now launches the opponent. It also does significantly more damage. Additionally, the translation for the name of this skill is slightly different. Previously, it was "I won't forgive you!" in place of "I'll never forgive you!".
"Ah, tranquility, seeping into a rocky crag, a cicada's trill"
(When "I'll never forgive you!" hits) //ON GROUND
The input for this follow-up has changed. Previously it was + // in place of //. The translation for the name of this skill is also different. Previously, it was "Cicada's cry etched in stone" in place of "'Ah, tranquility, seeping into a rocky crag, a cicada's trill'".
Sizzle!
+ //ON GROUND WHEN DOWNED
When ACT2 tosses its tail end, it's arc is now different based on what variant is inputted, with the and variants tossing the projectile a farther distance forward but at a lower angle. It also travels faster. The flames that the projectile leave on the ground now have a hitbox as well. If the opponent touches it, they will not take damage like they would if they were hit by the projectile, but they will catch fire and take damage because of that. The projectile can also hit downed opponents now. Additionally, the amount of damage it deals is much greater now and increases as the strength of the attack button does instead of staying the same across variants. All variants of the skill also have its damage distributed over two hits now instead of only hitting once.
Kaboom!
+ //ON GROUND
When this counter is successfully activated, the opponent is not flung nearly as far as they were in All-Star Battle. The damage dealt when successfully activated is significantly higher now though.
Boing!
+ //ON GROUND TRAP
Where ACT2 places the "boing" SFX now changes based on the attack button inputted instead of being placed at the same distance, no matter the variant.
Normals [Stand On] (通常技)
Standing Light Attack
ON GROUND
This attack now causes a soft knockdown when hitting jumping opponents.
Standing Medium Attack
ON GROUND
Echoes ACT3 moves out a significant distance now when it attacks. This attack also hits twice now instead of only once.
Standing Heavy Attack
ON GROUND
Echoes ACT3 flies forward a greater distance than it did in All-Star Battle.
Crouching Medium Attack
+ ON GROUND
Echoes ACT3 moves forward a greater distance than it did in All-Star Battle.
Crouching Heavy Attack
+ ON GROUND
Instead of causing a hard knockdown on hit, the opponent is now launched into the air, suffering a soft knockdown when they hit the ground. This allows Koichi to extend his combos naturally without any special conditions or costs.
Jumping Medium Attack
IN AIR OK
The hitbox of this attack has been extended outward, allowing for this attack to now hit grounded opponents. It also now launches opponents on hit and hits twice instead of only once.
Skills [Stand On] (コマンド技)
Hit them, ACT3!
+ //ON GROUND
While ACT3's travel distance still increases with the strength of the attack button, ACT3 travels a significantly shorter distance than it did in All-Star Battle for all variants. This results in the opponent not getting pushed as far away from Koichi now. All the variants also deal less hits, resulting in them also dealing less damage.
S-H-I-T
+ //ON GROUND WHEN DOWNED
Instead of pausing before barraging the opponent, ACT3 now continues its movement immediately once it rises into position. However, to keep the duration of the skill similar, ACT3 now punches and travels downward slower than it did in All-Star Battle. The variants also deal more hits now, with the number of hits increasing as the strength of the attack button inputted does. Additionally, Echoes does not travel all the way to the ground when it attacks, and while this doesn't affect typical gameplay, this means that this skill is no longer able to hit and slow down Sheer Heart Attack.
Wh-What is this wind?!
(While taking damage or guarding) + for 2 HH ON GROUND
The input for this skill has changed. Previously it was + // in place of + . This skill will no longer knock Koichi back, meaning it also no longer damages him. It also no longer damages the opponent either though. Furthermore, it now costs two stocks of Heart Heat rather than only a portion of a single stock. Additionally, the translation of the name of this skill has changed. Previously, it was "This air pressure!?" in place of "Wh-What is this wind?!".
Heart Heat Attack / Great Heat Attack (ＨＨＡ / ＧＨＡ)
Echoes ACT3: Freeze!
+ 2 ATK Buttons
ON GROUND
ACT3 delivers its barrage slower than it did in All-Star Battle.
Does this mean I've gotten stronger?!
+ 3 ATK Buttons or ON GROUND
The translation for the name of this GHA has changed. Previously it was "I'm really getting stronger?!" in place of "Does this mean I've gotten stronger?!".
General Changes
Koichi's run speed in User Mode has been reduced.
