Reborn as Ultron to travel the multiverse

So if you were given the chance to change your race what would you do. You would probably accept it and change your race in something like a elf a dwarf or even vampire but in my opinion all of those are so worthless so insignificant as they all will be shackled by one thing and that is there Flesh, what the point of being stronger, faster and smarter if your very race do not have the ability to adapt to change at your leisure and without consequence unlike the so called immortal vampire who does with a simple stake to the heart or mirror that reflected the sun just right witch will kill him instantly even if he has lived for 100, 1000 or even a 1,000,000 years. So follow me and let's see what I could do as a machine.
