The return of Belial in Season 9 signals more than just another boss fight—it suggests major story implications for Diablo 4's future. Here's why his comeback is significant:
Power Struggles in Diablo 4 Gold Hell
With Mephisto gone and Lilith defeated, the balance of power in the Burning Hells is shifting.
Belial may be using this chaos to establish himself as the next major antagonist.
Potential Alliance with Azmodan
In Diablo 3, Belial and Azmodan worked together to overthrow the Prime Evils.
If Azmodan returns, they could reunite to conquer Sanctuary once again.
Revenge Against Diablo
Diablo used and betrayed the other Evils in Diablo 3, absorbing their power.
Belial may be seeking vengeance, leading to Diablo IV Gold an eventual showdown with Diablo himself.
