Not for mortals

You're to be given exactly one tangible item that you desire. It can't be anything of the mundane world i.e. it should be something that couldn't possibly exist or defies the rules of the world as you know it. Example 1: An enormous statue of myself with a shining penis of pure gold that spans the entire known universe. Example 2: The One Ring. What is it?

The charisma of James Bond

Shotgun Gauntlets.

A truly everlasting gobstopper.

A girlfriend

Cybernetic implants that enhance my physical prowess, i.e. the stamina of a fucking race horse, the strength of a coked-out ox and the ability to have multiple full body orgasms, and the ability to cum buckets.

I'd like a hyperbolic time chamber. Just as long as it doesn't cut into my lifespan.

The ability to charm anyone I please without fail no matter what I do

The Ability to shape shift to and from a purple grape flavored slime girl at will.
Said slime girl will also have shape shifting, morphing, and stretching abilities.

A dimensional portal that allows me to travel to and from any and all alternate dimensions.

The Ironman suit.

A working TARDIS from Doctor Who.

Infinite stamina and never be in pain would do me fine.

I swear the human foot was not meant for standing on for 7 hours straight.
