Infinite energy reactors make no sense
Yes I know this is fiction, but still.
Let's say that the maximum output of 17's reactor is X Watts. Now if he trains and becomes 10 times stronger, suddenly his reactor can generate 10X Watts? How does that work? It's a mechanical device, how does it become more powerful just because he trained his organic body? And why not make the reactor that powerful to begin with? Why is there even a limit to the amount of energy it can generate per unit time, if it never runs out and can become more powerful?
