Mr Circ - A magician specialized with fire. 

Boss abilities:

• Fire shooting - Boss shoots fire bullets at you for 3 seconds.
• Hats summoning - Boss summons hats that leave a fire trail and chase the player.
• Clones summoning - Boss summons 2 clones that last for 5 seconds and fire bullets at you.
