I don't think there is such a thing as a half-Grimm. You are either a Grimm or you're not. Nick's father as far as we know was not a Grimm like his mom and aunt.

As for Zauberbiest, there appears to be a difference in powers and abilities between a full and half Zauberbiest. Sean has not shown telekinesis like Bonaparte, but appears to have enhanced strength and endurance compared to a human (something Grimms seem to have).

It all comes down to what effect the spell Adalind was using at the time Kelly was conceived, and if it will finally come into effect since the suppressant Adalind took wore off.

So if Kelly turns out to be a hybrid, the most likely option is that he will be a Grimm who is also a partial Zauberbiest, so perhaps his strength, endurance, and senses will surpass those of a normal Grimm or half-Zauberbiest. So perhaps telekinesis would be the least likely power he will have, but not to be ruled out, since Kelly being born of Grimm and Wesen (together with magic being used when he was conceived) is highly likely unprecedented.
