To answer your question DYBAD, the limit is Entropy. Absolutely every single thing that the D.I.N. does requires entropy, and if energy is used up, they can't re-use it. They also can't reverse entropy, so once energy is gone, it's gone. It's one of the reasons why they don't expand to the rest of the universe. If a civilization at their level encompassed the whole universe, then energy would be used up much quicker.

As for you, Discord:

1) Limitless. They can control their own sub-atomic structure to become practically anything they want. They don't even have to be conventional matter; they can convert their bodies into tachyons or whatever.

2) Nope. They can make a milkshake that never runs out because you can't see it. That being said, the rest of the milkshake has to be coming from somewhere. Matter is never created nor destroyed, after all.

3) They have stomachs with liquid plasma instead of stomach acid, and it instantly eliminates all food they swallow. Food consumption isn't really necessary for Neohumans since they can gain energy from their surroundings. Their brains also exist, albeit made out of femtomachines that allow them to transfer to other bodies and connect to Virtual Reality. They also have sex organs for reproduction. Other than that, nope, they don't have any other organs. No hearts and no blood vessels, no stomachs or other organs since their transhuman bodies can be entirely sustained by ambient energy and all waste products are just converted to more femtotech inside of their bodies.
