"Then, when all is in commotion, and we have created a race of our superior electrical beings in sufficient number, we will unleash the wild beasts, our electric rats, to destroy and feast on what is left of the humans."
This quote reveals the depths of Hatch's insanity. What began as a vague plan to make the electric children rulers of the world in the first book has evolved into a specific four-step plan to create a master race and annihilate the rest of the world's population. He plans to "destroy and feast on" the non-electric humans, creating a world of purely powerful people. This is the future Michael, the Electroclan, and the Resistance are fighting against: the extinction of humanity.
"If we fail, the world will fall into a state of captivity it has never before experienced – not in its thousands of years of recorded history. It would be Orwellian."
This quote from Simon, spokesperson of the Resistance, spells out the enormous importance of their fight against the Elgen. If they lose, Dr. Hatch will lead a world revolution under his electric protégés and institute a regime that resembles 1984 in its strictness and brutality. Simon is making a literary reference to underscore the undesirability of that terrible future.
"Nonel is the term Hatch uses to refer to nonelectric humans. It is ironic that Hatch himself is a Nonel."
Gervaso is highlighting an essential and ironic part of Hatch's character. He coins a (horribly cheesy) term to refer to the others, indicating a severe dichotomy in his mind between people who matter and people who don't. He puts himself in the former category, of course, but its only other occupants are the electric humans. The irony is that he himself is nonelectric, but he chooses to disregard that fact in his folly, assuming his value will outweigh his lack of powers.
