Sometimes villains battle one another. Let's say a three-way fight broke out between two sets of the Crushers and the Destroyers. Which group would win?

CRUSHERS: CRIMEWAVE TEAM
F.I.S.T.
Mercury Mercenary
Temper
Vulture
Bull
Shrew

CRUSHERS: CITADEL TEAM
Mocker
Hornet
Mace
Shocker
Stormlord
Marionette

DESTROYERS
Annihilator
Behemoth
Electrocutioner
Iron Maiden
Ratman
Shapeshifter

I'm of a mind to state Destroyers as well...but there are a couple of x-factors with the Crushers that make it a bit more of a tossup.  Merc Merc, Shrew, Mace, and - to an extent - F.I.S.T., Shocker and perhaps Marionette could put some real beats on Annihilator and his boys/girls.

A considerable element of this also relies not on just individual power-level, but also on the degree of cooperation and sheer team capability the specific groups would be able to muster.  In that respect, both Crushers and Destroyers would have a couple of standout strong points and potential crippling weaknesses.

In consideration, I honestly believe the Destroyers would do better against the entire Crushers group at once; there's every chance the dozen of them would end up impeding each other more than helping.  Against the individual Crushers' teams...might be a bit more of a straight-out face off.

Destroyers got my vote after some consideration. It came down to commitment and in a battle between ruthless people, the Destroyers seem more committed to the task.
