Hello...Well yeah, thats what I have been wondering for some time. Ive noticed it is pronounced slightly different in the different incarnations of the Transformers. In the G1 cartoon, it was pronunced "Ener-john" kinda like that. Similar to energy, only that and o replaces the y. In the Michael Bay movies, it is alsp pronounced "Ener-john", but also there are some individuals that pronounce it "Ener-gohn", the go syllable sounding like the one in gospel. Optimus pronounces it Ener-john, also Megatron, also Jetfire. But Starscream pronounces it "Ener-gohn", in ROTF, in the bit when he says "Without more Energon, the Hatchlings will gonna keep dying" I speak japanese, italian, english and my mother language is spanish, and in the latin-american spanish dubbing of the G1 cartoon, the word was pronounced "Ener-gohn", just like Starscream says it in ROTF. So, whats the correct form? At least in english, which would be the true form.
