Shadowbug Clone

The Shadowbug Clone is the final boss of the Subspace Event. Upon defeating him you get the message "The Subspace is Leaking into the World!" Once you receive this message, a new biome, The Trophy Realm, will spread from the top left corner of the world. When it spawns it looks like a mass of purple and black orbs that form into the player overtime. It uses Shadow forms of all the strongest items in your inventory (e.g. Meowmere=Shadow Meowmere, Armor=Dark Alternative of that Armor, etc.) and shares buffs with the player(s) fighting it.
