Justin Kurtew is normally seen in a leather duster. 

The duster is to hide certain changes to Justin's body. He has been unsuccessfully hybridized with a praying mantis. He has an extra joint in his forearms making his hands whiplash quick. He can retrieve a knife and kill an opponent before they even know he has drawn it.

Justin tends toward combative interactions with other people. Like a mantis, his temptation is to dismember and eat his victims. The worst thing possible is for people to cheer him on. It releases in him a killing instinct that quickly spirals out of control.

Justin lives on Basement 3 level with the unsuccessful hybrids.

We first meet Justin in Book 2 of The Human Hybrid Project, Inside the Darkness.
