If the blood of a Grimm is ever some how injected or consumed in the body of a hexenbiest, she will lose her powers and become a human and no longer be wesen… However, if a human ruthless enough to be willing to take the life of hexenbiest and cut out her heart, there’s a spell and various rituals that can be performed for said human to become a Hexenbiest but its a very long and extremely painful process and not just anyone can be approved, even if said persons goes through the effort it’s up to the magic and energies to decide rather to give such a power to another. In another episode, a very strong and revered Hexenbiest was able to bring her son back to life right after he died.

Adalind is a very talented witch and has even been able to make a spell to change her appearance as someone else completely, she’s very ruthless but does show care for a few things. her mother when faced with another Grimm fell to her demise when trying to defend herself. But not all Hexenbiests have powers as strong as others, depending on how pure and strong they are~ Adalind Schade for example (the first Hexenbiest shown on Grimm) has the ability to make people kill themselves as was shown in one of the episodes, vs. However, Hexenbiests are physically powerful enough to give Grimms a degree of trouble. They are not as strong as Grimms as on three separate occasions Grimms were able to gain the upper hand in a fight with Hexenbiests. They are able to casually overpower a grown man and rip him apart, but they can only access these powers in their Hexenbiest form and not their human one. Hexenbiests are also shown to possess superhuman strength. Hexenbiests are one of the most top feared wesen in the wesen world and past humans who knew of them are usually very afraid except for the royals of course. As far as I know they are meant to live along time as well, they are very wise but they can make choices too quickly based on defense and this can cause problems for them - If you watch Grimm you can see that portrayed. They are of course witches and practice witch craft but deal mainly in dark magic. They cloak themselves to appear very beautiful in human form but when they woge (turn to their wesen/real form) they look like zombies/corpses, their flesh is decayed and they’re very heinous and wicked, their strongest characteristic is being sociopathic which makes them stronger in their relentless efforts to keep who they are meant to be protected because they aren’t meant to get emotionally involved. Hexenbiests are said to be kind of like guardians of the royals, they’re also known to help them with spells and protection even in magic practices.

I am in love with that show! Out of all the wesen, honestly I relate to Hexenbiest the most. ‘Hexenbiest’ is from Grimm as far as I know of. No need to apologize I appreciate the inquiry ^_^
