Please define everyone, because I don't see many people on that level

"If anyone has a number of highly-trained, highly-skilled soldiers that were both naturally and genetically altered to war, with proper leadership and loyalty, then they could easily wipe out a superior-numbered force" Depends on the numbers

Anyway, Ducks classification of the Equestrians as second is superficial when you think about it. They may call themselves second place to the Collective when excluding the Supremes and Aetherii, but they are still trailing behind, so its hardly as if the supposed second place is coming close to the level you are talking about. What are the criteria for "highly advanced"?
