02Appearance
Parallel World Diego is virtually identical in appearance to the base world's Diego Brando. He is a young man of below-average height and slim to medium build. He has light hair, dark eyebrows, and light, bold eyes. He commonly wears an equestrian helmet with the letters "D", "I" and "O" mounted on bending pins emerging from a small ribbon tied at its front, a turtleneck jumper patterned with a diagonal grid, light, mid-forearm-length gloves, light, wide-legged breeches, and tall, dark riding boots.↗
03Personality
This incarnation of Diego Brando shares several personality traits with his base world counterpart: like the original Diego, he is misanthropic and ambitious above all, sharing his counterpart's desire for power and dominion over society. However, the methods by which he achieves his goals demonstrate far more overt cruelty and violent tendencies than the original Diego.↗
Parallel World Diego is self-centered and has no apparent capacity for empathy. Furthermore, he is absolutely ruthless, prepared to kill anyone in his way by inventively violent methods, including throwing knives, setting up wire traps, and even using gasoline and matches to burn others alive. He is capable of sacrificing innocent people without a second thought, going so far as to taunt Johnny for accidentally killing the adoring fans he uses to shield himself.↗↗↗↗
Due to his Stand's invincible power to stop time, Diego displays unshakable self-confidence and openly shows contempt for others. He only becomes distressed when he loses the upper hand or is shaken by an unexpected development, such as Tusk 's ability to move within stopped time. When he is cornered by Lucy, he finally loses control of his emotions, screaming with rage and disgust his disbelief that the girl would dare to defy him.↗↗↗
04Abilities
Stand
Parallel World Diego's Stand, THE WORLD, is a powerful humanoid Stand capable of stopping time for up to five seconds.↗
Horseback Riding
The original Diego Brando is one of the most talented jockeys of his generation, and his alternate counterpart demonstrates the same level of expertise in riding and handling horses.↗
05Story
SPOILERS
Background
Parallel World Diego's history prior to his encounter with Valentine is unknown. It can be inferred that, like the original Diego, he chose to participate in the Steel Ball Run race for the prize and prestige. Unlike his base world counterpart, however, Parallel World Diego chooses not to pursue Valentine onto a moving train, a decision that cost the original Diego his life when he was split in two by its wheels.↗↗
Late in the 8th Stage of the race, Parallel World Diego is suddenly confronted by the president of the United States, Funny Valentine. After being afflicted with the infinite Spin by Tusk ACT4, Valentine turns to Diego and his ambition as a final backup plan, in case his attempt to win Johnny Joestar to his side fails.↗↗
High Voltage
Parallel World Diego hides underground until Valentine is finally killed by Johnny Joestar. While Johnny, Lucy Steel, and Steven Steel are distracted, Diego emerges and steals the Saint's Corpse, hiding himself among the other top competitors of the Steel Ball Run race. Johnny eventually tracks down Diego, but Diego reveals his Stand, THE WORLD, and stops time. Remembering Valentine's advice, Diego is careful to avoid Johnny's nail bullet as he throws a handful of knives at the jockey.↗↗
Diego arrives at the 8th Stage's goal in second place, and quickly boards a boat to New York. Johnny boards a subsequent boat and pursues Diego into the alleys of Brooklyn, where the latter stops time again to prepare a wire trap for Johnny. Caught off guard by the wires, Johnny shoots the wall to both shield himself with the debris and attack Diego from the resulting hole. As the hole catches up to him, Diego stops time as Tusk ACT4 shows itself and prepares to slice off its arm.↗↗↗↗
The World of Stars and Stripes
Johnny exits the sewers and rejoins the other competitors as they approach Brooklyn Bridge, preparing to shoot Diego from the very edge of his range. Diego stops time once more to create a pincer move: as he fires a gun at Johnny from in front of him, THE WORLD moves to attack him from behind. As time resumes, Johnny turns to face THE WORLD, causing Diego's bullet to pierce him in the neck and topple him from his horse.↗
Heeding Valentine's advice, Diego rides directly to Trinity Church, placing the Corpse in the vault beneath the church. As Diego prepares to seal the vault, Lucy Steel appears behind him with an object wrapped in cloth. Diego uses THE WORLD to pin Lucy against the wall. After confirming that no one has followed her, Diego interrogates Lucy as to her plans.↗↗↗
