Recommended Strategies

Quickman is quite tough for an early boss, since he can't be hit when he's standing still, or hopping from square to square. You can only hit him when he's unleashing an attack. Fortunately, he doesn’t have too much Hp, which is his weakness, so hit him with chips like Gutsman (or Airman, if you got it from his ghost) which are high power chips at this stage of the game, and you should be able to defeat him.

V2 is like going to KotoSquare except when you see the security cube you go to it then turn left.
V3 randomly appears in KotoArea.
He is one of the hardest bosses in the MMBN2 game, because you have to hit him while he is attacking. A suggestion is Toadman V2/V3 with a whole bunch of Attack+ 10/20/30 and Navi+ 20/30/40 and Elec+ 20/30/40 and the Gater P.A. While he is jumping around, just stand in one spot (on the middle tile for people with slow reflexes). Once he attacks dodge, come to the front row, and use multiple Toadman V2/V3 or just one with four power adding chips once the custom gauge is full. Once he is paralyzed immediately go to the screen for the Gater P.A of rid chips. Once you defeat him, save.

Another easy way of beating Quickman is to use your Flamethrower (if you have a Heat Style) while Quickman is skipping around the panels; he'll easily be nailed by the Flamethrower for up to 100 points damage per hit.
