One bite is a vampire / oneshot hybrid which entered KOTH.org's 94nop hill on 3rd May 2007 and survived 101 challenges before being pushed off on 1st December 2008.

;     Vampiring  is a strategy  that  is rarely  used  nowadays,  but  has a big
; potential.  One bite (pushed  off at the age of 101 @ 94nop)  is an attempt to
; make a modern vampire. It is a pure vampire in the sense that it does not uses
; scanning  and only throws  jmp bombs at .33c.  It may not seem like much,  but
; other advantages (airbag, slim profile) compensate for low speed.
;     Enemy is vamped into djn #0, #0 pit. When main loop detects that the enemy
; process  has been trapped,  it jumps to SSD clear that immediately  overwrites
; the pit with spl carpet.  When fighting a scanner,  there is a chance that SSD
; clear has been found and overwritten  with SPLs.  Even in this case,  One bite
; may  still get a win if it manages  to hit the enemy,  as the trapped  process
; will eventually fall through the djn pit and die.
;     Step that forms a pattern  where bombs are 7 cells apart is used,  because
; we  don't want  to accidentally  stun  ourselves  if djn  in the  clear  falls
; through, and that requires a gap of 6 cells between jmp bombs.
