other powers I just learned Vixen has (because she is the animal kingdom)
heat resistant iron skin/shell from the Volcano Slug
photosynthesis from the leaf slug
EDIT: something I just realized could be possible is a "bubble bullet" via a pistol shrimp
while the cavitation bubble technically shouldn't be possible on land, I think the magical nature of Vixen's connection to the Red could compensate for that. it's the same way it compensates to create the conditions for her to fly without wings. shooting an on-land cavitation bullet would definitely put her on a different league, it's basically the closest thing our planet has to a straight up ki blast. plus, the grip strength, speed, and power pistol shrimp output to create that effect is no joke.
