The HP parts series are NaviCust parts that increase MegaMan's HP value.
When bugged, HP parts cause two different bugs:
- The Battle HP Bug causes MegaMan to continuously lose HP during the turn, depending on the level.
- The Damage HP Bug occurs whenever MegaMan is Flinching or receives an attack that applies Drag. It increases the current Battle HP Bug level by 1.
Notes
- The maximum HP Bug level that can be caused through the Navi Customizer is level 3.
- The level of the Battle HP Bug can be increased up to level 7, in which MegaMan looses 1 HP every 10 frame.
- Since bugging an HP part gives two bugs, it automatically widens the range of
Static by 2 levels. - HP+300 has the same size and shape as AttackMAX which makes them interchangeable.
Competitive Overview
Having more HP allows the player to survive more damage from the opponent, hence making it harder for the opponenet to delete them. While MegaMan has a base HP of 1000, it is strongly recommended to have at least 1500 HP, due to the many high damage dealing chips.
Counterplay
While having much HP let's you withstand more damage from your opponent, that isn't enough in order to win the game. In the case of decreased Custom times caused by 
FstGauge, turns pass by much quicker. This can cause a situation in which having more HP might result in the player loosing to Damage Judge if they didn't dealt enough damage.
