Diavolo/Misc

Trivia

 * Diavolo's character was probably inspired by the song "21st Century Schizoid Man" by King Crimson, since he is a 21st century man and his two personalities share schizoid traits. Furthermore this song and Epitaph were released on the same album, In the Court of the Crimson King in 1969 and together as singles in 1976.
 * Given the circumstances of his defeat, Diavolo is neither dead or alive. He is in an endless cycle of deadly situations. Along with Kars and Magenta Magenta he suffers a "fate worse than death", condemned to never die.
 * Diavolo is the second antagonist to have a Stand whose key ability involves chronokinesis and the third overall to have chronokinesis.  The first is Dio, who can stop time, and the second would be Yoshikage Kira's Killer Queen's Bite the Dust, which rewinds time.
 * According to a Top 10 List published in Weekly Shonen Jump in 2000, Diavolo is Araki's second favorite antagonist and 4th favorite character overall.
 * Strangely, despite his fervent desire to destroy any and all things connected to him that could have exposed his identity (up to and including his own daughter), he spared Donatella.
 * His desire of keeping his identity a secret from anyone is very similar to Yoshikage Kira's desire of no one finding out about him, and like Kira, Diavolo kills anyone who tries to find out about him or, in Leone Abbacchio's case, anyone who tries to send information to others about his identity.
 * However a key difference here is that Diavolo has a split personality, he shifts into physically and mentally to stay hidden while Kira has to get rid of any evidence of his murders using his Stand.

Golden Whirlwind
Diavolo appears as the enemy faced on chapters 12,13 (as "The Boss", where only his silhouette is seen), 18 and 21, as he utilizes King Crimson to, in the game's perspective, alter time so he can take the advantage.

On 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 he throws him away (much like he did to Buccellati on his story debut) 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 about how Diavolo's see King Crimson's effect. However, during chapter 21 you play as Giorno Giovanna with Gold Experience Requiem, if G.E.R is not activated Giorno will not be able to counter attack, if G.E.R is activated, Giorno will stay slow, but Gold Experience Requiem can freely move, this is due it's power (returning something to "point zero").

All Star Battle
Diavolo is a playable character in All-Star Battle. As expected of one of the seven main antagonists, Diavolo is stronger than most characters, though his lacking moveset limits the combos that can be used. His Stand, King Crimson, is one of the more dangerous stands in the game due to it's Epitaph and raw strength. King Crimson's power can also works as a "dash" for Diavolo, if the player taps forward two times in a row, Diavolo will "skip" time and appears a little more forward than his original position (the same goes to tapping back-forward or left and right sides).

Diavolo's HHA is Epitaph, allowing him to see into the future with 100% accuracy, while in this mode, Diavolo dodges most of the enemy's attacks automatically with a Stylish Action but without depleting his Guard Gauge. King Crimson's GHA special works as a counter-attack: if the enemy hits Diavolo during one of his poses, the screen will enter into King Crimson's world for a short period of time (similar to the first time Bruno Buccellati was attacked by the Stand), during this time the opponent is unable to move, allowing Diavolo a chance to make a high level attack, if Diavolo got hit by the enemy, he will shows that actually was the "future" and he managed to prevent that by appearing behind the enemy and makes King Cirmson chops the opponent's head (similiar to how he "killed" Bruno Buccellati).

Diavolo is the only villain from Part V 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", while his second features the football team T-shirt he wore to disguise himself and manages to kill Abbacchio. For two of his victory poses, Doppio is used instead of Diavolo.
