(I'll comment, but mainly on the idea she's top 25, not top 5)
Except 1 or 2, she's always won but he's pretty consistently hung in there for a bit.
But he's also largely trying to avoid her and just keep away. And he can normally play keep away much longer against strong foes than that.
There are also indirect showings like Catwoman/Batman owning Cheetah
Those simply showed *massive* misunderstanding of Cheetah's power level, they were writing her like the animated version (who's a scientist mutated by cat DNA, as opposed to a god). Cheetahs have taken down Flash and Superman.
Compare to Cheetah owning the Secret Six... while not using her speed. Bane comes at her, she gently shoves him into a wall, etc.. They got away by pointing a high power electricity villain at her.
The Secret Six is almost all highly skilled fighters, and they were badly outmatched against Cheetah, even as a group.
on different occasions and I believe Ra's beat Diana in a sword fight.
Trinity mini-series, non-canon elseworld (it had a few other problems like her lasso being easily broken. That WW is lower power than canon one, Wondy normally gets the short end in elseworlds).
