After Catstrong's Defeat (Who's real name is Owen Charles Renderox), the heroes encounter APEX, he was experimenting Cyborg Guard, Wolfen came, and APEX retreats, the Heart of Chaos prepares for a fight one last time. Rules: Be Balanced, no max stats rule for now. Don't be big or small. Be sure the Boss damages you and the heroes heals you. Don't be OP. Don't remove anything unless its yours. (Or requested.)
Merc is back for the third time, looks like he couldn't get revenge on APEX, but hey, he helps destroy the Heart. Fix any bugs, please.
