Ichigo Kurosaki was born with four bloodlines including human, Shinigami, Hollow and Quincy. Ichigo Kurosaki has evolved many times throughout the series, each time almost always stronger than the previous version. Let's take a look at Ichigo Kurosaki 's forms on his journey to becoming the strongest character in the Bleach universe.
Ichigo's Mugetsu defeats Aizen at his peak
Mugetsu is Ichigo Kurosaki's ultimate technique after 3 months of harsh training in the Dangai dimension. The perfect fusion with Zanpakuto Zangetsu gave Ichigo the terrible power to destroy Aizen's Hogyo. He appeared with a new form that looked like longer hair and mysterious chains wrapped around his arms.
Aizen has tremendous power after absorbing Hogyoku, turning him into a person with a terrible amount of Hollow. Ichigo, not giving up, launched the final attack, Final Getsuga Tensho. Ichigo's form completely transformed with gray cloth covering his body. Thanks to his Mugetsu, Ichigo with the destructive power pierced through Aizen. However, Aizen still lived until he was sealed by Urahara's secret Kidou.

Fullbring Ichigo under the guidance of Kugo Ginjou
Having lost his Shinigami powers, fate once again led him to accidentally discover his latent Fullbring ability after Ichigo decided to embark on a rigorous training journey under the guidance of Kugo Ginjou.
Ichigo Kurosaki transformed into a skeleton warrior with his entire body covered in hard armor. Fullbring gave him the ability to create powerful Reiatsu energy vortexes, not inferior to Getsuga Tensho in power. However, luck smiled on Ichigo when Ginjou stole his Fullbring, opening the way for Rukia to pass on the Shinigami power. However, the power that was once expected, became one of Ichigo's weakest abilities when compared to the original Zanpakuto power.

The moment of realizing the harmony between Quincy and Hollow
The journey to the Kingdom results in Ichigo's Bankai being cut in half by Haschwalth, and this journey is also the turning point that makes Ichigo realize the inseparable harmony of Quincy and Hollow through lessons from the swordsman Oetsu Nimaiya who teaches him how to communicate with Zangetsu.
Nimaiya has created a masterpiece sword while Ichigo possesses two extremely powerful black ones. Ichigo now possesses the ability to utilize multiple sword techniques at once including the devastating Getsuga Juujishou . Unlike Getsuga Juujishou, this power allows Ichigo to use both swords.

Ichigo's True Bankai
With a single movement of his two swords, Ichigo Kurosaki unleashed the hidden power that created the new Tensa Zangetsu. The ivory-white blade glowed with a mysterious chain wrapped tightly around it. Ichigo's appearance also changed significantly: a sharp horn protruded from his head and black lines ran down his face.
This form is similar to Tensa Zangetsu that Ichigo faced in Jinzen. Yhwach realized this and had to use Almighty to completely destroy Ichigo. Fortunately, this power was restored by Orihime and Tsukishima.

Ichigo's final Zanpakuto after defeating Yhwach
Ichigo Kurosaki's final form left fans gasping. While Aizen and Renji were still important pieces, it was Uryu Ishida who delivered the decisive blow. It was the young Quincy's Still Silver arrow that created enough space for Ichigo to charge straight at Yhwach with Tensa Zangetsu.
Ichigo's Bankai shatters to reveal the original form of the sword that Rukia gave him. It's like a return to the past, to the moment when Ichigo's Shinigami powers were born. Still, this is definitely one of Ichigo's most powerful moments in Bleach.

In short, Ichigo has been constantly evolving with each new form being a leap in power from attack to recovery. Which form of Ichigo Kurosaki do you like the most? Leave a comment below Hobiverse's article!
