The Metroid Prime Series (1-3)is one of my favorite game series of all time. I wanted to kind of make a tribute to it by making a coaster but adding a little gun-killing action. I also wanted to put in a kind of end boss such as: Metroid Prime, Dark Samus, and The Arua Unit. So I added the blue beast and named it: Prime Unit. I wanted to also kind of add in Space Pirates by adding Snarlys. I really like Metroid. So I hope you do to.
