It will always be the same spirit, except it grows stinger- e.g. when Ichigo first had a Zanpakuto, it was nameless, but Zangetsu lied within. He had to "awaken" it, thus "changing" it. The power is still the same, just a new look.

I didn't say Zangetsu's power changed, changes to Zangetsu are reflected in Shikai and Bankai appearance. After Zangetsu and Ichigo's hollow merge Ichigo's bankai changed appearance. Therefore, Zangetsu appearance should be different now that his Shikai and Bankai looks different.

But my concern is why we no longer see Zangetsu.
