One of the early things in Gwenpool was that even a joke villain is still dangerous and competent if the situation calls for it. Gwen even says in this issue that she’s worried about Batroc going back to being a joke due to another writer ignoring his character here.

During the JLA/Avengers crossover, Batman fought Batroc the Leaper. He defeated him but only after having a long battle with him and called him "one of the strongest adversaries he ever faced"

They guy who defeated Superman had trouble taking down Batroc
