You get... BUCCANEER HIJACK!!

You get this weapon from defeating Buccaneer Woman. borockman summons a remote control, that emits a frequency that overrides a minor enemy's programming. This effectively makes the minor enemy an ally of borockman. The new ally keeps its original attack pattern. Only one enemy can be affected at any one time.
