The Scarecrow, also known by his real name Kenneth Jesperson, is a removed character from Manhunt.
However, his persona of a tramp suddenly changes whenever he puts on his mask and he becomes suddenly violent, wielding a home-made axe. During Halloween, Scarecrow puts a pumpkin on his head.
The following was taken from the bio included with the Scarecrow artwork.
Bio - Formerly the head hunter amongst the Smileys, Kenneth Jesperson was stripped of his mask and rank for being responsible for the Piggsy debacle. Now chastised and long past simple derangement, he sleeps rough in the streets of the arenas, desperately hoping to find and kill Piggsy and redeem himself in the eyes of the commander and his sponsor..... Dressed in rags he resembles any other derelict until he dons the mask and weapon of his scarecrow persona.
Weaponry - Jesperson has a crude yet deadly home made axe wielding it with savage intensity.
Audio - If encountered as a tramp, Jesperson just makes indistinct mumblings and typical drunken rants, however when transformed into the scarecrow his past as a smiley comes to the fore and he descends into maniacal tittering and sibilant hissing.
