Acoording to naruto series, slug, frog and snake are three way deadlock. So snake>frog>slug>snake. If you dont believe me ,you can watch naruto shippuden. Forgot the episode no. But its a hilarious part including gamabunta and katsuyu in the frog bar.Poor use of A>B>C logic. Tsunade and her Anbu guards survived without Katsuyu as well. Is that supposed to be a feat worth mentioning?
And yes, he is. That is exactly what is shown in the Manga regardless of you wanting to believe it. Katsuyu cannot beat Manda and an exchange ends up with Katsuyu being defeated without someone saving her.
