My ideal body (that includes very specific things such as it being unaltered by time or any kind of force exerced on it (in other words eternal and indestructible), unless I will it, this body's muscles are also infinitely strong when needs to be... flight, space travel, no need to breath, extreem speed (higher than light for space travel) etc etc.... in all, a body like the one I alread have but with the age thing added).
The power to control life and death (and age) on any other being (So I could raise the dead and make them young again)
Omniscience.
