The ability to gain the properties from anything I consume followed by the ability to ingest anything without dying. This has the power to evolve endlessly and assuming I could find a piece of someone (even a clump of hair or after eating a dust mite even a few dead skin cells should work) I would be able to gain any abilities that they possess at the time said thing was a part of them.
Of course I am hoping that I don't have to manifest the form of everything I have ever consumed at once because if I did, I would end up looking like an Eldrich Abomination by the end of the week.
