"HOOH BOY, don't let the name and stats fool you. His AI difficulty is set to two by default and thus he might have an AI of moderate difficulty at its peak performance. And also, you can now fully control him without needing to configure the settings!

That said, this is one of my preferred edits I've done in a while, as it really had been a long time coming."
