Some of you don't remember Super Mario Brothers 2, but for those of you that do remember that game., it was one of the best Mario games to be released by Nintendo. Now more to the point. Let's start with the 'basic' characters of spiral knights, say those little birds that are always flying to an fro. Now, if only they had a mask covering their face, then they would start to look more like a Nintendo-est character.
And let's not stop there, what about King krogmo?
Remember the final boss in Super Mario Brothers 2 what was his name.. Wart?
If you also pay close attention to the devilites, maybe they were all lay-offs from a dead game and found refuge here?
This even includes all the other monsters, drones included.. I'm just saying the similarities are far too obvious.
They clearly aren't obvious enough. No one has ever made these weak connections before.
