Hey Kyurem147. I'm sorry I'm late. Got sidetracked with category cleanup & addin' new pics. Also caught seein' vertical lightnings & rainbows today.

That's an excellent question. The answer is simple: Robotroplis is a location & a namesake city like Akkaba Metropolis (named after one of Apocalypse's 2 faithful cults), while the Eggman Empire is a group & a eponymous dictatorship like the Vigoor Empire (named after Vigoor) and the Gestahlian Empire (named after Emperor Gestahl).
