I can say that most of Silver's boss struggles are due to the fact that his PK was programmed after said bosses, and the coders of those bosses were long gone in order to make changes. I'm sure new coders will turn up at some point XD In the meantime, it's also a game of balance. I once had Silver able to grab both A.N.N.'s and Metal Knuckles's energy shots. It resulted in A.N.N. being defeated in less than 15 seconds and Metal Knuckles getting chucked off the screen and the game being unbeatable. Might upload a video of that second one for giggles later. As it stands, expect Metal Knuckles to be a whole lot different in later releases. The line between difficult and cheap is a thin one, but it's a work in progress.
