This is an interesting thread. While Frenzy is awesome, I think Venom is a bad match for her. So Venom for the majority.

Frenzy beats the breaks off of Venom. She oneshotted She-Hulk.

That requires high heral level strength. Is that the usual level she operates at or a high showing? Because Venom has plenty of those. And he's very difficult to put down. Especially with brute force.
