Day 4! The grand queen bitch herself, Infinity!
She's known as the "Tyrant Queen" because she stole the throne from her mother and caused mass mayhem. One of the worst galactic queens out there! which is saying something! I adore her though, she's the catalyst of a lot of the stories in monstra, and if shes not a direct cause she's at least connected to them.
Though shes the mother of Nova and Solar, so she did something good at least.
