Basically the international hero course is the best international hero course in the world, the HQ is also like MASSIVE. It has a much more advanced technology and training, meaning that everyone there becomes very powerful if they ever get the chance to study there. ‘Elites’ are the elites of the school, the strongest, kinda like the big three in a way.
