I think if Vixen has the right marketing or tv show/movie her character could really be popular. Just read an article on readers digest about animals with special abilities and was blown away with what some of them can do. Bumblebees have a sixth sense. Sloths can survive any wound. Lyrebirds are master imitators. they can mimic chainsaws, car alarms, a dog's bark etc.. I imagine with this she could mimic Black Canaries sonic cry. Sea cucumbers can regenerate their organs. Vixen can be a multiple organ donator or just pull out her heart and pretend to be dead when going out against an enemy. and then regenerate it. Vixen probably needs a compendium that highlights her mimicking animals with unusual abilities. I would like to see her use super speed against a bunch Amazo robots which forces her to use multiple animal mimicking in a short period of time. This would really highlight what she can do.
