Summary
- The antagonists of the series, Bleach Aizen Sosuke and Yhwach will battle with each other
- Ichigo will use the most powerful form of bankai to defeat Yhwach
- Yhwach awakens the almighty power of the Quincy King
One of the most exciting hypothetical fights in Bleach Thousand Year Blood War is those, where the main characters Ichigo Kurosaki, the protagonist, and Aizen Sosuke, the antagonist of Bleach face Yhwach together. It shows that all the characters are so powerful that if join forces they are capable of posing a great threat to Yhwach the Quincy king.

Battle for the Seireitei and Soul Reapers
The battle starts with both Ichigo and Aizen starting a double strike. For a time during their confrontation, Aizen employed the use of the Kyoka Suigetsu to fake numerous opportunities to strike Yhwach. Ichigo produces these moments as opportunities for high-speed attacks and Getsuga Tensho blows. However, Yhwach’s Almighty allows him to change these scenes, and thus most of these initial attacks are useless.
Yet they know it would be impossible to go around the Almighty so Aizen and Ichigo change their approach. For this reason, Aizen decides to tease Yhwach into underestimating his ability with complicated illusions. On the other hand, Ichigo performs unpredictable, high-temperature rises to try to disrupt Yhwach’s future altering. A special technique that plays on the difference between Ichigo’s brute force and Aizen’s wits puts Yhwach on the back foot.

Kurosaki and Sosuke’s strong blows against the Quincy King
When the fight becomes more spirited, he takes on the full strength that involves Hollow powers as well as the Quincy powers. Aizen going even further might increase his destructive powers, he fires Kido spells that are damaging. Despite the show of power of Yhwach, the humility of Ichigo going for a full-on attack and Aizen’s full-on tricking puts the battle on an even keel. Still, if the enemy is Yhwach, who absorbs almost all strengths including Mugetsu or Hado No. 99 – it remains a problem.

The drive to change something could appear if Aizen manages to take advantage of the temporary inability of Yhwach to manipulate the future. Aizen was able to create a complex Zanpakutō illusion that not only even fools the Almighty for a split second. Ichigo could then capitalize on this and strike with a finishing blow although this can only be given a speculation as the ending is left wide open for a new and perhaps more enhanced form of Getsuga Tensho.
The end of the Thousand Year Blood War between the Quincies and the Soul Reapers
Yhwach proceeds to declare that his powers let him wipe out the future and even his death and Ichigo tries to strike him again – but is knocked back by a burst of black Reiatsu as Tensa Zangetsu disintegrates. Since Reiatsu has spread even to Shakonmaku, Yhwach shouts that both the human world and Soul Society will become one before his power; but he gets interrupted by Uryu shooting an arrowhead of Still Silver through his chest since Still Silver can counter Yhwach’s powers for an brief moment after coming in contact with his blood as explained by Uryu’s father. As Yhwach’s Reiatsu weakens, Ichigo picks up Tensa Zangetsu and by Uryū’s command jumps towards him.
