What do you guys think of this guy's theory since this thread is getting ridiculous.

So let’s get the obvious things out of the way.

No, Ichigo very clearly doesn’t have some rule creating power like other characters.

Symbolism is clearly something Kubo likes to use instead of outright explanations.

I’m just a guy yapping who’s liked bleach since I picked it up in middle school. Feel free to disagree or tell me where I’m wrong. I got thick skin.

TLDR: Ichigo is heavily inspired by Kali, the Hindu goddess of…a lot really. Transformation, destruction, yet also love and nurturing, the power of the universe. Thus I believe Ichigo’s power is complete destruction, to be death for those that cannot have it. I believe Ichigo’s role at the end will be the force that completes what the original soul king seemed to set out to do: to create an end for those that cannot.

Kali does not represent only destruction of outside forces. She represents destroying inner demons such as fear, ego, attachment.

So where does this leave Ichigo?

Tensa Zangestsu once had a sauvastika, a symbol that is associated with Kali. Ichigo has genuine transformations based on his defeat of ignorance, dual natured in ferocity and kindness. Protector and destroyer.

And couple that with the knowledge of the arc that shall not be named that too strong of souls go to hell, and the fact Yhwach genuinely seemed to fear his Bankai, leads me to think Ichigo’s power is death. Purification. Destruction at its highest level to create something new.
