Not only are Linx and Jinx the reincarnations of two powerful beings from billions of years ago, but they also have five forms.
Their human form is the form they naturally take, which is their first form. It would allow them to blend in like how Pickle Berry, Nari, and Kathy are doing.
Then, there is their second form, which is their enhanced human form, in which everything about them is enhanced by three times for five hours every day.
Just like with Nari, in this form, all wounds would be healed, regardless of how badly injured she was in her human form.
Their third form is their demi-beast form, which they call their Extreme Yin-Yang form. According to them, this form allows them to become one with their respective energies.
Linx becomes one with the yang energy, and Jinx becomes much colder thanks to her yin energy.
