Here is an impulsive taken screenshot of my first endboss (ever). A classic 4 - part boss with some classic weak points and ... ahh you have to find out your own when the game is finished (in a year or so...maaaan....).
I built it out of some parts i got from my great npc drawing friends.
And yea, its def. inspired by mother brain. Its just my favorite endboss ever (even better than most HD 3D Superbosses of god of war etc.)
