Absolute Storage

How overpowered would a being be with:

Main power: absolute storage (and with the unique ability to use this power as a medium to store their imagination and bring forth whatever they stored into existence; including powers.)

Passive power: absolute regeneration

Acquired “power”: absolute body

Now this power is definitely broken when used by someone who knows what their doing…anyways what concept (personal concept to be specific) would you guys store?

For me it’ll be the concept of limitation which’ll allow me to gain almighty ascension..or just nigh-omnipotence

So, absolute storage right? Since this power allows the user to store absolutely anything and manipulate anything that has to do with Storing things. Would a user of this power be able to store their imaginations (specifically what they imagine or thought) and then bring said imagination/thought into the physical plane? Like something similar to Gilgamesh’s gate of Babylon but you store your imaginations (and everything else you wanna store) and bring them forth into reality…kinda like imagination manifestation.
