Nigel and Sebastian

Nigel and Sebastian is the carnival freak boss of the Carny level of The House of the Dead: Overkill. Nigel is a dim-witted giant roughly three times the size of the average human, while Sebastian is a well-versed tumor-like growth protruding from his stomach. Nigel is apparently dependant on Sebastian for survival, and will protect his conjoined twin above all else. However Sebastian is fully capable (if crippled) of surviving without Nigel.

They are initially seen gnawing on the head of a struggling mutant. Upon spotting the players, Sebastian commands Nigel to attack, excited by the prospect of "good eats".
