Stigorax

A ruthless and intelligent predator encountered by the Doctor during his time in 25th century Birmingham. Stigorax embodies calculated malice, stalking prey with precision and adapting to its environment with predatory efficiency. Its presence alone triggers immediate responses from patrol creatures like Fifi, signaling the regime's descent into overt violence. The Doctor's recognition of its howl as a harbinger of danger underscores its reputation as a persistent threat, one that lingers in memory as a symbol of unchecked brutality.
