Hmm, there are a few pairs that could work:
Wrath and Ruin (probably what you were going for)
Death and Destruction (credited to the good Baron)
Crash & Burn
Blood & Gore
Boom & Bust
Eradicate & Annihilate
Smash & Tear
Tyranny & Villainy
If you don't mind a few added suggestions:
Sigrid's Fury & Sigrid's Wrath
The Revenant & The Necromancer
The Brother's Grimm (ha just kidding
)
You could also try something involving the four horsemen of the apocalypse.
Or legendary twins from mythology.
