Aquaman's trait does not work on fully charged low laser and bite combos when executed properly.
Bite is punishable, indeed. He gets 20% + knock down. If bite connects, Zod gets 40% + knock down. The mix up is in your favor.
I either do the mix up or fill the screen with force balls and end with MB low laser + more force balls to waste time for the trait.
I have beaten all Aquaman players who have tried to out turtle and/or out zone me, including Tom and Theo. However, when the fools start playing footsies, I start losing. Zod cannot compete with b+1,2, which leads to 40% combos and 45% combos with background interactable objects, so I see no point in rushing down. You cannot afford to lose that much damage in this match because winning becomes very, very difficult.
