Bug

Bugs
Bugs are glitches in Megaman.exe´s program. This glitches may cause a varienty of side-effects during a battle.

Reasons for having bugs
Many things can cause a bug. This are usually:

-Break a NaviCustom rule: If the NaviCustom is not used properly, then megaman can have a bug. The bug depends on which NaviCustom part was used to break a rule.

-Use of Bugstyle or Hub.BAT: The bugstyle, as its name points, creates many bugs. The bugs of this style can either be good or bad depending on just luck. The Hub.BAT (which, during BN2 can only be accesed by using Hubstyle) imitates every style from BN2 with its abilitys, making it the best style, (or the best NaviCustom part in BN3-BN6) but it creates a HP bug that halves the HP of the player. This side-effect was no longer in the Hub.BAT during BN6.

-Get hit by a bugbomb: In Battle Network 6, there is a "PvP only" battlechip that can bug the other player. Effects are random, but unlike the Bugstyle, there only can be negative effects
