Fight Shocker again:
You can see Shocker even after you have defeated him. Sometimes in a City Event, Shocker will appear and you must fight him. It will not be a Boss battle, though -- just a fight against a street thug, who has some very powerful blasters. Note: He is also stronger than all street thugs.
See Boomerang:
Boomerang can also appear in a City Event.
