If the Japanese series was still G1 and seems it was mentioned as Atlantis: 1. Where was King Nurgill and his subjects? 2. His kingdom sunk in the ocean nearest America so it wouldn't have gone anywhere- was the Victory story taking place in America? 3. With all the advanced high-technology post movie and beyond, why didn't Galvatron bring his Decepticons as he had knowledge of how to harvest the energy (he certainly would have learned about this)? 4. If Galvy harvested the energy the way he did in Atlantis Arise, would he be powerful enough to take on Deathasaurus? Something just doesn't feel right!
Don't look too deep into it, continuity can get preeetty loose between not only G1 itself, but JG1 as well.
