The Star King

As well as being the final boss and 2 phase, it is actually two bosses. Starting with King Cepheus, he is surrounded with a ring of spiked balls, rotating clockwise. Towards the beginning, he will try to keep you in one place with three thick chains that have a big green arrowhead on the ends facing you for a short period. Once you beat him you will fight Royal Pupils (his eyes). Like the triangle baddies from earlier in the campaign, these two balls will shoot green fire from three points on each eye. When you beat it. You’ll get a little constellation (and credits)
