Renard is the bastard brother of Eric Renard, born to a Hexenbiest.
As such, he is a half-Hexenbiest (or technically, half-Zauberbiest) aware
of the supernatural world and has plans to use Nick as a Grimm
to his own advantage since Nick has not yet learned where he fits into
the world. He protects Nick from all harm but is determined to make
sure no other Grimms are nearby.

As he is half-Wesen, he can woge, but very rarely does, even in moments
of extreme tension. He also seems to possess some Zauberbiest powers,
such as superhuman strength. Renard is also highly trained in hand to
hand combat, and was able to fight Nick on a near equal level, a feat few
have accomplished.
Renard is a great marksman, as well as a capable leader, a charismatic
speaker, and is very good at keeping secrets. Multiple organizations think
he is on their side.

Zauberbiest (TSOW-bər-beest; Germ. Zauber "magic"
or Zauberer "wizard" + Biest "beast").
