Err..., mimicking the stature and grow a longer end-tail spike just because a monster saw it is pretty... impossible... and unnecessary.

While I agree that she might took over some attacks of other monsters after she saw it, but the internal organs can hardly copied from another monster. I believe she just evolved a stronger flame sac and produces/gathers another chemical for using stronger attacks. Also the strength just comes with a better adaptation and evolving stronger muscles, for that she doesn't need to copy anything.

And from what monster exactly did she mimic the gas attack or the Doragyurosu lightning if she comes to none of the areas to meet them (I don't know if she lives also in the Highland but on the page there is at least nothing noted that she does)?

With that only Espinas remains what I think could be possible.
