Cosmotron, the guardian of space

Cosmotron is a hard mode/war mode post-Moon Lord boss. He can be summoned using the Cosmic Idol.

Appearance
He appears to be a floating entity with a humanoid figure. You can say he is the space itself for he is entirely made of galaxies, stars, or even universes.

Behavior
Unlike Clockwork, who is totally passive, waiting for your death, this boss is a huge pain in the head. He hovers over you and spams lots of attacks covering the screen that the chance of dodging is very little. He can shoot falling stars at you, summon black holes, supernovas, quasar lasers, and big bang for expert mode. Hopefully, this guy has less HP than Clockwork.
