|“||Reality itself, bend to my will!!||”|
—Heaven Ascension DIO
Originally existing from an alternate universe where he killed the Joestars, this DIO achieved his goal of "obtaining heaven" and as a result, has obtained complete god-like powers and the "ultimate Stand" referred to as The World Over Heaven.
DIO is dressed in a long white robe and white chaps with a golden trim, adorned with golden kneepads, golden boots and a belt bearing a "D" motif and arm cuffs engraved with his name. His chest is covered with a white tank-top and an Egyptian-esque neckpiece that bears a "D" on it. DIO's hair is much longer, while his skin has taken a slight purple hue; not unlike Star Platinum. His face itself now has a golden star on his forehead with ceremonious markings running down his cheeks repeating the word "DIO"; the marks themselves are similar to Enrico Pucci's hair once he created Made in Heaven.
Heaven Ascension DIO originally existed in an alternate reality whereupon the events of Stardust Crusaders ended in tragedy for the Joestar Group. DIO succeeded in killing all members of the group along with Jotaro Kujo. Now free to pursue his original goals of "obtaining heaven", DIO collected the 36 sinners required alongside Enrico Pucci as he evolved his Stand and became the perfect being with godlike power, Heaven Ascension DIO. Now unrivaled and unstoppable, DIO proceeded to conquer the world and rewrite humanity.
Around this time, during the ending of Steel Ball Run, President Funny Valentine tried desperately to escape from the "infinite spin" set on him by Johnny Joestar. In the process, Valentine skipped through dimensions until he eventually came to the reality belonging to Heaven Ascension DIO. DIO used the power of his Stand, The World Over Heaven to remove the infinite spin from Valentine and in return, Valentine told DIO of the Saint Corpse Parts and that his reality was merely an alternate branch of the main dimensional universe. Having already conquered his world and desiring the satisfaction of doing so to the original universe as well, DIO used his power to travel through dimensions; resurrecting his fallen acolytes and brainwashing new ones from other timelines to serve as his army.
DIO, armed with the Spine of the Holy Corpse, set his followers out to battle the Joestars and their allies. He patiently waited as his brainwashed minions were defeated one by one until the Joestars collected all of the remaining Corpse Parts. DIO then summoned the Joestar Group to his realm, where he easily defeated Gold Experience Requiem and Tusk ACT4. DIO stole the Corpse Parts from the group and planned on sacrificing them to perform the ritual of "obtaining heaven" all over again to increase his powers even further. However, Jotaro managed to hang on to his Corpse Part and escaped along with the others.
DIO, now irritated but still collected, spread out the Corpse Parts to his generals and sent them to eliminate the Joestar group. In the meantime, DIO managed to discover that Valentine was secretly a turncoat and was trying to discover which of the Joestars possessed the power to defeat DIO. Confronting Valentine about his treachery, Valentine fought DIO throughout many dimensions but in the end, lost. DIO, not wanting to waste such a powerful Stand user, offered Valentine forgiveness in exchange for his eternal loyalty. Valentine, however, retained his integrity and refused only to be swiftly killed by DIO. DIO then confided in his friend, Pucci about how he was troubled over the Joestars in this timeline being more problematic than he anticipated. Pucci reassured him that everything would go according to his plans and went off to confront the Joestars himself. Pucci ultimately lost to Jotaro and his daughter, Jolyne Cujoh. As Jotaro questioned Pucci about the secret to DIO's Stand, Pucci instead committed suicide while pledging his love and service to DIO even in death.
With Jotaro and the others having re-obtained the other Corpse Parts, they traveled to Cairo where DIO planned to face against them all in battle. DIO fought against Jotaro and Johnny and subsequently lost. However, he negated the damage done to him using The World Over Heaven. Jotaro, now witnessing DIO's power up close, discovered his Stand's ability to overwrite reality itself through the use of its fists. DIO claimed that Jotaro knowing his secret was futile and banished the other Joestars, excluding Jotaro and Jolyne, to other dimensions to stall for time to charge his Stand's power. As the others proceeded to battle their brainwashed allies, Giorno Giovanna realized too late that it was a trap. DIO unleashed the full power of The World Over Heaven and killed all of the Joestars and their allies before absorbing their souls into himself.
Now gloating over his victory to Jotaro and Jolyne, DIO combined the Saint Corpse Parts with the 36 souls to ascend to an even greater form of existence, causing the fabric of space itself to start crumbling away. Jotaro and Jolyne teamed up to take down DIO. While they managed to defeat him, it was a temporary victory as DIO healed himself once again and killed Jolyne before absorbing her soul as well. DIO proceeded to deliver a fatal punch to Jotaro as he gleefully relished in his victory. However, Jotaro mysteriously negated the damage done to himself which caused DIO to recoil in shock. DIO remembered that Star Platinum and The World Over Heaven are still the same type of Stand and by DIO evolving his Stand, he inadvertently caused Star Platinum to evolve as well.
Now armed with Star Platinum Over Heaven, Jotaro regained his composure as DIO began to break down. DIO, trying now to quickly kill Jotaro, let out an attack only to punch the armlets of the original timeline's DIO. Jotaro had secretly acquired these armlets after Valentine informed him that if two identical objects from different dimensions collide, they will violently cancel each other out. The armlets fused and exploded with DIO's current ones, resulting in both of his arms being destroyed and leaving him powerless. DIO desperately tried to use his blood to blind Jotaro, however the attempt proved futile; just as it did in the original timeline. Mirroring his original downfall, Jotaro delivered a single final punch to DIO, which caused his body to crumble and explode as hundreds of souls poured out of him.
With Heaven Ascension DIO dead, the timeline reversed itself into a new timeline where the events of Eyes of Heaven never took place, yet caused every heroic fatality throughout the original universe's Parts to be negated. This ultimately resulted in a universe where none of the Joestars and their allies died, bringing about an era of peace.
- Main article: The World Over Heaven
DIO's evolved Stand, The World Over Heaven, in addition to his ability to stop time, can now overwrite reality itself as well. This also allows him to rewrite anything within any timeline (except for changing his stands range), granting him godlike power.
The World Over Heaven also retains The World's original super strength, speed and incredible precision, but more enhanced than Part 4 Jotaro's Star Platinum: The World.
DIO in his ascended form has the powers of teleportation, instantaneous regeneration, resurrecting the dead, mind control and can summon lightning bolts to attack and target his opponents. He also appears to have the ability of dimensional travel, similar to Valentine's D4C.
This form has a weakness of being connected to his self from Part 3's timeline. As no two versions of the same person or thing can co-exist in the same dimension, should Part 3 DIO or something connected to him, like his golden bracelet rings, come in contact with Heaven Ascension DIO or their matching item, both versions will collide and explode.
- While Funny Valentine is immune to mutual destruction when two versions of himself coexist in one dimension due to his Stand D4C, Heaven Ascension DIO does not share the same trait. When the bracelet of DIO from the original timeline comes into contact with Heaven Ascension DIO's bracelet, they both explode.
- This version of DIO is unplayable and only meant to be the final boss of the game.
