The biggest question is the fans Whiten manga has included The Millennium Blood War is the rushed pacing and barebones exposition that many characters and plot lines have. Due to Tite Kubo's rapidly declining health, he was unable to write the arc the way he wanted. He had to rush the story to get to the end he envisioned before his body succumbed to his many ailments. The other half of the arc suffers from this. Many characters' fates are left unanswered, many plot points are barely resolved and character development is not fully fleshed out.
With Tite Kubo's involvement in Bleach: Thousand-Year Blood War anime production, he tries to correct this problem with the original manga. Working alongside series director Tomohisa Taguchi, he added tons of new scenes to the story that further expanded on what was established in the manga. And the last Quincy, Uryuu Ishida, is perhaps the biggest recipient of this.

More background for Quincy's face
Manga readers knew that Uryuu Ishida would eventually betray Ichigo and the Gotei 13, but the build up to this was always very lacking. Readers have hardly any explanation behind his betrayal. However, the anime adaptation of Thousand-Year Blood War built heavily on this. Already in part one, Uryuu gets several new scenes, further expanding his involvement in the war. He is shown reading his grandfather's diary and learning the truth about the war a thousand years ago. They also hint that his mother may be involved in his father's motives for renouncing Quincy.
In part two, he gets even more new scenes, giving him more time with Jugram Haschwalth and the other Sternriders. This further helps the audience believe that what they see in him is not what it seems. The audience gets the suspicion that Uryuu might be hiding something. In this way, Jugram acts as an audience, always suspicious of Uryuu. There is a constant lingering sense that something is hiding behind Uryuu's apparent betrayal.

Uryuu's new powers in the anime
A true Quincy
During the Quincy Royal Guard's battle with Senjumaru, Uryuu now shows hints of his newfound ability. Uryuu is now Sternritter A -The Antithesis, an ability that allows him to turn the battle in an instant. And that's exactly how he defeats Senjumaru. Uryuu gets a brand new fight with Squad 0's representative. He leaves behind a power far beyond anything he's ever shown before that allows him to overcome the Soul Reaper's extraordinary world-shattering powers.
And now with the latest episode of the series, he has a brand new battle with his best friend, Ichigo Kurosaki. Here he shows more of that incredible Quincy power he's been given thanks to his king. He can effortlessly conjure and shoot arrows without even showing a Quincy bow. And most importantly, he now shows an ability that he had never used in the original manga, Vollständig.

A brilliant episode with an invisible battle between Ichigo and Uryu, who has defected to the Quincies and will help Yhwach collapse the kingdoms.
Uryuu's Vollständig is one of the biggest anime-only additions Tite Kubo has given fans to properly develop their beloved characters. Part two gave characters like Shinji Hirako and Senjumaru Shutara brand new Bankai. The former was already established in the Can't Feel Your World novels, but the latter had never been given such honor, even in supplemental material. Senjumaru's Battle with the Royal Guard was anime only and so was this new battle between Ichigo and Uryuu.
Tite Kubo and Studio Pierrot continue to blow away fans and everyone's expectations with every episode of Thousand-Year Blood War. So far, part three has been a huge departure from the source material in the best possible way. Instead of completely changing the story, the anime has shown completely new material that enhances the impact and emotional weight of Bleach's final arc. As well as fleshing out all the possible plot points and characters that needed help to further deliver the fantastic storytelling that Whiten is known for.
We're only a few episodes into part three and, as writer Tite Kubo said earlier, this part will see the largest number of anime expansions of this series. Fans are more excited than ever to see what else will be added to the story of this incredible anime. Right now, Quincy Survivor is the talk of the town thanks to his extraordinary new stages and powers.
