Sasuke IS Uryu

Uryu Ishida and Sasuke Uchiha share lots of  similarities it's not even funny anymore. In facts, I'd go as far as to say that they're the same person. Allow me to make my case. 

THE LONE SURVIVORS 

At the beginning of both series, Uryu Ishida and Sasuke Uchiha are introduced as the last survivors of their respective people: the Quincy Race and the Uchiha Clan. Each of these clans was wiped out in a devastating massacre, with Uryu’s people (the Quincy) being exterminated by Soul Reapers to prevent a greater catastrophe befalling the cycle of life and death, while Sasuke’s Uchiha clan was slaughtered by his older brother, Itachi, under orders from the Hidden Leaf village inorder to foil a brewing coup which would have destroyed the village whether or not it was successful. 

However, the “sole survivor” narrative doesn’t hold for long in either case. In Bleach, it is later revealed that Uryu’s father, Ryūken Ishida, is alive and has distanced himself from the Quincy heritage and Uryu himself. Similarly, in Naruto, us viewers were introduced to Itachi later on in the story after assuming Sasuke was the one and only Uchiha left. In both cases, us viewers are forced to reassess their identity as the last surviving members of their clan/race when these family members resurface.

TRAGIC CLAN LEGACIES AND THE PATH OF REVENGE 

Both Uryu and Sasuke are deeply shaped by the tragedy of their clans’ destruction. Sasuke’s entire arc in Naruto revolves around his pursuit of revenge against his brother Itachi for slaughtering their family. This desire for vengeance consumes Sasuke to the point he defects from the village, leaving his friends behind and seek out strength under the tutelage of Orochimaru and later becoming a key player in the Fourth Great Ninja War.

Uryu’s motivations, while less centered on revenge, also stem from a deep loyalty to his heritage. As a Quincy, he initially harbors resentment towards Soul Reapers: becoming a foil to Ichigo Kurosaki for a time. Blaming them for the near-extinction of his race. His quest for power and identity leads him down a dark path when he aligns himself with Yhwach, the Quincy king, during the final arc of Bleach where not only does he become a Sternritter, but declared Yhwach's successor. 

Both Sasuke and  Uryu's loyalty and decisions are influenced by his clan's tragic history and the actions of its elders.

THE PATRIARCH AND THE GREAT WAR 

Another parallel arises in the final arcs of both series: The Fourth Great Ninja War, and the Thousand Years Blood War respectively. Here the true scope of the protagonists’ clan/race histories is revealed. 

In Bleach, Yhwach, the progenitor of the Quincy, returns to lead a massive war against the Soul Reapers and destroy the Soul King inorder to revert all existence to its prior state where the line between life and death becomes blurred to nonexistance. 

Similarly, in Naruto, the history of the Uchiha clan and their connection to the Sage of Six Paths is unveiled, leading to the resurrection of Madara Uchiha, the legendary Uchiha leader, who seeks to plunge the world into eternal darkness by using the Infinite Tsukiyomi to put every living person under a genjutsu where they live their best life. 

Both Yhwach and Madara represent the ultimate expression of the Quincy and Uchiha power, wielding godlike abilities that include manipulation of time. 

Yhwach absorbed powers of his Sternritters as his own, in addition to The Almighty: an ability that allows him to see all possible futures and pick whichever one he wishes to happen. This grants him near-omnipotence. 

Madara on the other hand gains the Rinnegan, Hashirama Cells, and Becomes the 10 Tails Jinchuuriki. This grants him the deepest pockets in terms of Jutsus and abilities in the whole of Naruto Shippuden. His most notable jutsu is his Limbo clones which exist in a different dimension, can interact with his own, and are near impossible to sense or deal with without Six Path abilities. 

Both antagonists serve as the final obstacle in the great wars that conclude Bleach and Naruto, respectively, bringing the tragic legacies of their people to a head.

THE POWER OF THE EYE 

This isn't about Uryu and Sasuke directly, but about their progenitors. In their final forms, Madara and Yhwach both gained at least 1 extra eyeball: Madara's one Rinnesharingan on his forehead and Yhwach's many eyes of the Almighty. Just wanted to point that out before moving on. 

MASTERS OF ARCHERY

Both Uryu and Sasuke are one of, if not the best archers in their respective series. While it's pretty obvious for Uryu, Archery isn't the first thing that comes to mind when viewers think of Sasuke, with his swordsmanship and all. 

It was revealed in a filler episode that Itachi taught Sasuke to use a bow, his proficiency in the art didn't reemerge until his Susanno evolved to the point it was revealed his weapon was the bow and arrow. He could fire these at such insane speeds, only the fastest individuals in the verse have any hope of dodging them. 

Overtime he began adding Amaterasu to the arrows or even firing arrows made of Amaterasu entirely. It's even his strongest attack: Indra's Arrow. 

For Uryu, however, Bows and arrows is his whole shtick. He's very proficient in Quincy Arts used over a 1000 years ago. In fact, he uses the bow way more often than his modern quincy counterparts. Despite this, he's not disadvantaged and can toddle with the best of them. 

CONCLUSION 

Uryu Ishida and Sasuke Uchiha serve as parallel figures in Bleach and Naruto, respectively, embodying the themes of loss, revenge, and redemption. Both characters share the burden of their clan’s tragic legacy, wield powerful abilities rooted in their bloodlines, and experience complex journeys of self-discovery. Their arcs mirror each other in many ways, from being the last survivors of their clans to facing off against powerful patriarchal figures in the final wars of their series. In the end, Uryu and Sasuke stand as two of the most iconic rivals and allies in the world of anime.
