All-Star Battle R/Parallel World Diego

"THE WORLD... it's Me Time now. (オレだけの時間だぜ)"

Parallel World Diego (並行世界から来たディエゴ), along with THE WORLD, was confirmed for as the fourth paid DLC character on May 31, 2023. He is slated for release on June 16, 2023, or June 14 for season pass owners. Like the first three paid DLC characters, he is included in the game's first season pass, and consequently the Digital Deluxe Edition and Ultimate Edition as well.

As in, Parallel Diego's name is localized as "Alternate World Diego" in the English localization of All-Star Battle R. Furthermore, THE WORLD's name is fully capitalized, differentiating it from 's version of The World.

His moveset is similar to that of his appearance, with modifications made and new aspects added to better fit in with All-Star Battle R's different gameplay style.

As the voice actor for Parallel World Diego, among other iterations of Dio Brando, since Eyes of Heaven, Takehito Koyasu reprises his role in All-Star Battle R as well. As with the majority of the game's roster, voice lines for Parallel World Diego were either added or re-recorded.

Gameplay
Parallel World Diego has 920 health and uses the both the Mounted (騎乗) and Stand (スタンド) Battle Styles, fighting foes with Silver Bullet and THE WORLD. During a fight, he can use several different attacks that were featured in Steel Ball Run. Unlike most other characters that use the Stand Battle Style, Parallel World Diego cannot manually summon and dismiss his Stand; instead, the Stand remains active as long as the user is dismounted, and appears instantaneously for any attacks that utilize it while the user is mounted.

Three parts of the Holy Corpse will slowly appear scattered across the stage when Parallel World Diego is a combatant. He can pick up these pieces to receive blessings that boost his performance in combat. If Parallel World Diego is pitted against, , , , or another Parallel World Diego, both players will have to fight over the three Corpse Parts, as only one set will appear.

 * input={{ASBInput|S}} {{Input|on ground}}
 * desc=Parallel World Diego can summon his horse, Silver Bullet, to mount it, or dismount and send it away while summoning THE WORLD, shifting his movement and available abilities. Silver Bullet improves his basic mobility, attack range, and power. However, he loses the ability to Stylish Guard and will be forcibly dismounted if he is hit by a move that hard knockdowns. To note, Parallel Diego's Guard Gauge will not regenerate while he is Mounted unless he is in possession of all three Holy Corpse parts.

If the Style input ({{ASBInput|S}}) is chained from normals while unmounted, 'Quick Mount' is triggered at the cost of Heart Heat, whereby Parallel Diego mounts Silver Bullet much faster, and the act of flipping onto his horse can knock the opponent into the air. This provides an easy and quicker method of mounting as well as transitioning Diego's unmounted combo into a mounted one. }} {{Game Move|name=THE WORLD!|Color=SBR
 * input={{ASBInput|2}}x2 + {{ASBInput|S}} {{Input|on ground}}
 * desc=If Parallel Diego has a minimum of one and a half stocks of the Heart Heat Gauge, he can use his Stand's signature ability, "THE WORLD!". If the lengthy start-up animation completes, Parallel Diego will stop time for 3.4 ~ 6.9 seconds depending on how much of the HHG he has; The ability normally takes several seconds to activate and leaves Parallel Diego especially vulnerable to being interrupted, but executes drastically faster if he has a full three stocks of Heart Heat when performing it.

All animations, including the HHG flame and the countdown on the battle timer, will temporarily cease, and the opponent is frozen in place and completely unable to act. Damage dealt to the opponent that is not a Throw or HHA is reduced, but the opponent is otherwise absolutely vulnerable. When the ability ends and time resumes, the opponent will suffer all damage dealt to them at once.

Any projectiles unleashed through Parallel Diego's various abilities will hang in the air (knives thrown via "I'll skewer you!", the jerrycan tossed via "My trial is to conquer and kill at all costs.", and the lit matches thrown via "This is where the fun begins..."), notably doing more damage if they hit the opponent after time resumes than if they were to have connected immediately. Parallel Diego may use his HHA with impunity if he has enough Heart Heat to do so. He is even capable of hitting opponents that were down when the ability was activated, 'resetting' them into a standing position once hit. The ability is best used with normal attacks in mind in order to deal the most damage within the stopped time, as they execute quickly and their damage reduction within stopped time is insubstantial.

If Parallel Diego's Throw or HHA is used, time will immediately resume with the HHG drained to zero; As his GHA requires Silver Bullet, it is unavailable in stopped time.

If fighting against DIO or either version of Jotaro, Parallel Diego can use this ability to begin moving within the opposing fighter's stopped time, and may even outlast his opponent if their Heart Heat depletes before his. }} {{Game Move|name='''It's useless.

 * input={{ASBInput|3|M}} {{Input|on ground}}
 * desc=THE WORLD slowly delivers an overhead chop that leaves the opponent crumpling, striking as a middle attack that cannot be blocked crouching. This is a command normal that can chain into Parallel Diego's skills. (Comboable)
 * type=Middle

 * ref=
 * input={{ASBInput|236}} + 3 ATK Buttons, or {{ASBInput|G}} {{Input|on ground}}
 * desc=Parallel Diego's GHA can only be performed while Mounted, and will automatically summon Silver Bullet if used while Unmounted. Stating aloud that he has a plan, Diego has Silver Bullet lunge forward in a forceful full-body tackle. If it connects, the opponent is knocked back as Parallel Diego quickly jumps to the ground, summons THE WORLD, and stops time. Pulling out a revolver while his Stand advances toward the frozen opponent, he takes a bullet from the cylinder and roughly strikes its primer against the hammer of the gun to ignite the propellant (as the gun cannot normally fire in stopped time).

Reloading the bullet and lifting the revolver up to eye level, Parallel Diego carefully takes aim at the opponent's neck. He finally resumes time, allowing the shot to discharge as THE WORLD throws a hefty punch aimed at the opponent's face. A slow-motion shot of the opponent's shocked expression is shown, and the two attacks connect at the same time, completing the assault and blasting them away. }} }}
