The Big Bang is a boss of a Challenge 2 in Epic War 4.

Epic War 4
The Big Bang is a giant bomb that appears in challenge 2. Unlike other bosses it never stops moving no matter what (unless the player uses the skill called "Time Stop"). It must be destroyed before getting too close to your castle or it will destroy your castle. If the bomb is destroyed, then any units fighting the bomb will die (unless the player uses the skill called invulnerable). The best way to win is to destroy the enemies castle as early as you can.
