I can say Nina is pretty good at medicine, thanks to increased mental capacity, intensive training and natural talent, and also specializes on toxins.
She is also highly perceptive with four senses and in combination with K9 she is very good at tracking. She is capable of infiltration and pretty good with long arms/carrying modified hunting riffle. Standard athletic training, including diving and parachute. Also experienced in HtH combat, specilized in Wildcat MA.
Fenrir is hunter&killer. Also able to detect magical threat. Also...able to hunt its prey, scarred as hell, all the day, .
