The music is "Finger on the Trigger", it's just extremely slowed down. Bonus: I made an Inves Myst sprite, which includes Overlord Byakko Myst. Having a more nature-themed foe would contrast the mostly technological aspect of games like this, so it would be refreshing. Rules for signing up: Don't use a google image cause I won't be able to make it. Put your A.I. in the Notes and Credits.
c2a Overlord Byakko Myst(or OLBM for short) is a version of Myst that has been turned into an overlord inves through some Kamen Rider Gaim shenanigans or something. He would not appear at first, but sooner or later he will come through places where vines are growing. He cannot see(for the most part), so he will rely on sounds and touch to get around; so make too noise and it will create a free trail for him to get to you, although he will not always come to you straight away(he is an Overlord Inves, so he isn't a complete monster). The only way to make him go away is by playing "soiya!" through the cameras or by putting up your doors when OLBM is nearby. Special mode: Helheim Night - Only OLBM is active, but on full alert.
