This thing is the source of all hate and corruption in the scratch universe. It resided in Haipa Shinoru, before later on manifesting in Omega. After Omega's heart was defeated though, the Heart of Corruption was freed, meaning it can possess other beings, but it's evil has also subsided in it's vessels, letting their true untainted colors shine. The Heart of Corruption cannot be hurt or destroyed. It's first target is Troll-ge, which will fully turn them into The Trollge.
