Could Ichigo Have Won Without the Final Getsuga Tensho?

In the anime series Bleach, Ichigo Kurosaki's utilization of the Final Getsuga Tensho during his climactic battle against Sosuke Aizen is a pivotal moment. This technique grants Ichigo immense power but comes at a significant cost, as it results in him losing his Shinigami powers afterward.

The Power Level Disparity

By the time of their final confrontation, Aizen had reached a level of power that surpassed most characters in the series. Thanks to the Hogyoku, he transcended the limits of a Shinigami, mastering powerful techniques like Kido and achieving near-invulnerability. His abilities made him a formidable opponent across the series.

Ichigo's Growth and the Final Getsuga Tensho

Throughout the series, Ichigo had undergone significant growth in power. However, Aizen's strength was on an entirely different level. The Final Getsuga Tensho represented the culmination of Ichigo's training and power, allowing him to challenge Aizen directly. This technique provided the raw power needed to confront Aizen effectively.

Strategic Advantage and Surprise Element

The Final Getsuga Tensho not only provided Ichigo with the power needed to fight Aizen but also allowed him to surprise Aizen, who had become overconfident. This element of surprise was crucial in turning the tide of the battle. Had Ichigo not relied on this technique, the result might have been different.

Limitations of Other Techniques

Ichigo's previous techniques, while powerful, were not enough to overcome Aizen's defenses. The Final Getsuga Tensho was specifically designed to be a last-resort, capable of delivering a decisive blow. Without this technique, the outcome of the battle might have been uncertain.

Alternative Scenarios and Speculation

Some speculate that if Ichigo had killed Aizen earlier instead of engaging in battle, he would have retained his Shinigami powers and the power from Dangai training. This would have allowed him to carry the Dangai training into the future arcries, specifically the Time Training With Byakuya (TYBW) arc. However, it is uncertain whether Aizen's fight with Yhwach would have changed the story in this scenario.

In conclusion, while it is theoretically possible that Ichigo could have found another way to defeat Aizen, the narrative strongly suggests that the Final Getsuga Tensho was essential for his victory. It served as a necessary sacrifice to achieve the power needed to confront an overwhelmingly powerful foe. The Final Getsuga Tensho, despite its high cost, is a critical element that ensured Ichigo's ultimate triumph against Aizen.
