Diavolo/Misc

Golden Whirlwind
Diavolo appears as an enemy in Chapters 12 and 13 (as "The Boss", where only his silhouette is seen), as well as 18 and 21, where he utilizes King Crimson to, in the game's perspective, alter time.

In Chapters 12 and 13, he just "teleports" near the player, pretty much how a normal person would see the effects of King Crimson, he also uses a strong hook that crosses the player's body and then throws them (simialrly to his attack on Buccellati in the manga) and punches the floor trying to hit the player with stones.

During Chapters 18 and 21 when Diavolo uses King Crimson, he creates a "slow motion" effect on the screen (with inverted colors), where only Diavolo can freely move, making this version Diavolo's point of view during King Crimson's effect. In Chapter 21, the slow motion effect can be enabled when activating Giorno's Gold Experience Requiem.

All-Star Battle (PS3/PS4)
Diavolo is a playable character in All-Star Battle. As one of the seven main antagonists, Diavolo is stronger than most characters and his ability to cause massive damage per hit makes up for his limited combos. As one of the majority of playable characters in the game with the "Stand" Style, Diavolo can turn King Crimson on/off, changing movesets. Though unlike the vast majority of Stand Users in the game, he does not have access to the Stand Rush ability that returns from the Capcom game; None of his skills allow him to attack in conjunction with his Stand.

King Crimson acts as a powerful Stand whose melee attacks knock the opponent off their feet. When it is on, Diavolo's Heavy air and ground attacks down the opponent, and his crouching Heavy attack knocks the opponent into the air; His crouching Medium attack fills in the role of tripping the opponent. These melee attacks can be used to set up combos as his skills lack the potential to.

Exclusive to Diavolo is the ability "Erasing Time", activated automatically by skills marked with a star. During this brief period of erased time, the opponent cannot move, and Diavolo is invincible. Time returns after a moment or as soon as Diavolo performs an attack or skill.
 * I've eliminated 0.5 seconds!: Replacing the common forward and backward dash, Diavolo erases time to 'teleport' short distances, granting him small bursts of invincibility.
 * Time has been erased...: A counter. This skill is marked with a star. Diavolo and King Crimson pose, and if struck by a non-Throw/HHA/GHA, "Erasing Time" will activate.


 * Such futility!: This skill is marked with a star, and can only be performed as soon as Diavolo is hit by a non-HHA/GHA attack. "Erasing Time" will activate, and Diavolo will left be completely unharmed. This skill's function is similar in effect to "Time has been erased..." but consumes the Heart Heat Gauge as it is not a counter that can be triggered by the opponent.

While King Crimson is off:
 * Throw - You're not getting away!: King Crimson hoists the opponent up by their collar and delivers a devastating punch to the face.
 * The passage of time resumes!: Diavolo summons King Crimson to deliver a punch to the opponent's abdomen. leaving them crumpling to the ground (Comboable). This move can be charged to eventually increase its range and become unblockable, but Puttsun Cancel is required to follow-up on the charged attack.

While King Crimson is on: Diavolo's HHA activates Epitaph, allowing him to see into the future with 100% accuracy until the bar is used up. While in this mode, Diavolo dodges most of the opponent's attacks automatically with a Stylish Dodge without depleting any of the Guard Gauge, and any of the opponent's attempts to Stylish Dodge are nullified as well.
 * This is the end!: Diavolo summons King Crimson to punch the ground. The punch has enough force to emit a shockwave, downing the opponent if they are hit, and capable of hitting an already-downed opponent. This move can be used twice in the same combo without a reduction in damage on the second use.
 * Your life is mine!: King Crimson chops the opponent down the middle. Diavolo's skills can be instantly performed following this move. (Comboable)
 * King Crimson!: A Throw. King Crimson executes a short jab. If it connects, King Crimson will punch the opponent twice, hitting them into the air, before hooking them in the face with enough strength to send them flying. This Throw cannot be comboed into.
 * Now I'm really angry!: A Throw. King Crimson jabs at an upward angle. This move acts as an anti-air. It has the bonus effect of hitting opponents taller than Diavolo without them needing to be airborne. If it connects, King Crimson grabs the opponent by the face and slams them into the ground hard enough for them to bounce. Using its other fist, King Crimson punches the opponent in the abdomen and sends them flying.

Diavolo's GHA, "Pinnacle of Eternity", as with his other abilities that activate "Erasing Time", works as a counterattack: Diavolo will smile as he and King Crimson openly present themselves to the opponent. If he is then hit by the enemy with any form of short-to-mid ranged melee attack that is not a Throw, including HHA and even GHA, Diavolo's GHA will activate. Diavolo will disappear and reveal that what the opponent actually hit was their future selves, appearing behind them shortly afterward. Diavolo promises to end the fight as King Crimson delivers a singular powerful chop down the middle of the opponent. Notably enough, this GHA deals roughly 42% of the opponent's max health in damage, making it the most powerful Great Heat Attack in the entire game.

Diavolo is the only villain from Part 5 to appear in the game as a playable character and also the only character to have 2 characters appearing during his intro (Diavolo and Doppio). Diavolo's first alternate costume reflects his initial appearance as "The Boss"; completely disguised in shadow and wearing a tuxedo, while his second features the football team T-shirt he wore to disguise himself and kill Abbacchio. For two of his victory poses Doppio is used instead of Diavolo, and Doppio speaks several of his own (his "phone's" ringtone, answering the phone, his statement about the world being filled with idiots, etc.).

Eyes of Heaven (PS3/PS4)
Diavolo and Doppio were confirmed for Eyes of Heaven alongside their daughter and Buccellati.

Tournament
He is paired with Joshu Higashikata in the Eyes of Heaven tournament, but was eliminated in the preliminaries by Buccellati and Trish.
