Official summary
Gregor is one of the twelve Sinners. ProjectMoon’s manual describes him as comparatively easy to deal with in personality while emphasizing spontaneous physical transformation.
Transformation risk
The official profile says strong emotion or an abrupt environmental change can cause parts—or potentially all—of Gregor’s body to transform into insect-like tissue resembling a carapace.
How the manual frames him
ProjectMoon advises the Manager to control visible disgust rather than treat Gregor rudely. It notes that he can speak cynically but remains someone who can be reasoned with.
