My sona's complete eyes.

I always associated myself to dimensional travels, so it's no wonder I based myself on that.

My hat once was a cover to a wormhole on my head, then a living being capable of traveling through dimentions, then my actual self, then just a gadget again.

Able to travel over the limits of the imaginable, entering people's minds and everything that could be interpreteded as a universe, the only price was my own life and own soul.
