Other appearances
Although the castle itself had not actually appeared yet in the Mega Man Archie Comics series, it was mentioned in Issue 34, where Break Man tells the other third generation Robot Masters, including the recent recruit Shadow Man, to convene at the castle's building site and finish it up. It was mentioned again in Issue 36, during Flash Man's status report to Dr. Wily, and in Issue 37, citing that, even if Mega Man, Pharaoh Man, and Bright Man managed to escape his trap, it still will buy his Robot Masters enough time to finish up construction of the castle.
