Benjamin Fuest seems an anomaly in the Corona Tower's basement warrens. His final hybridized form hasn't revealed itself yet.

Benjamin has a large forehead with a small mouth, bordered by heavy eyebrows and a scraggly beard. His face lights up when he smiles, although he rarely does. 

Benjamin tends to point out the negative in situations before noticing the good that surrounds him. 

Benjamin's erstwhile DNA contributor is that of a caterpillar. It is hoped that he will undergo a metamorphic change into something more. A butterfly, perhaps? No one knows for sure.

We first meet Benjamin in Book 5 of The Human-Hybrid Project, The Glass Siege.
