BugFrag Trader

BugFrag Trader (Merchant)
In MegaMan Battle Network games, BugFrag traders are merchants who exchange various battle chips or Navi Customizer parts for varying amounts of BugFrags. These merchants are notable in that they often are the only sources of rare Battle Chips that cannot be obtained through other means, and in each game starting from BN3, one of these merchants always holds a Giga Chip which requires at least 100 BugFrags to trade for.

BugFrag Trader (Machine)
A form of chip trader found in MegaMan Battle Network 3 Blue and White verisions in Secret Area 3. This trader allows the player to trade 10 BugFrags for a Chip. The trader can give out many kinds of chips, including V4 Navi Chips with the exception of the other version's exclusive Navi chip. For example, in the Blue version, you cannot obtain MistMan V4 battlechip, eventhough you can obtain his V1, V2, and V3 chips through the BugFrag Trader; same thing holds for the other version and BowlMan chips.

By using the trader 30 times (i.e. trading 300 Bug Frags), the player can then face Bass GS, an upgraded version of the regular Bass (certain other conditions have to be met: defeated Serenade, which in turn requires the player to have completed their Regular 200 Chip library).

This trader also appears in the subsequent MegaMan Battle Network Games.

Tip: In order to get multiple bugfrags quickly, fight Gutsman.EXE in the world three headquarters. Countering him will result in you getting 10 bugfrags. This works for any Navi, but Gutsman is the easiest to counter.
