The HP parts series are NaviCust parts that increase MegaMan's HP value.
When bugged, the HP+ parts causes two seperate unique bugs:
- The Battle HP Bug causes MegaMan to continuously lose HP during the turn, depending on the level.
- The Damage HP Bug increases MegaMan's Battle HP Bug by 1 level when hit by a damaging attack without having Super Armor (causing him to flinch) or a damaging attack that inflicts Drag.
Notes
- The Damage HP Bug can only be obtained from the NaviCust.
- The maximum Battle HP Bug level caused through the Navi Customizer is 3.
- The Battle HP Bug level can be increased up to 7, in which MegaMan looses 1 HP every 10 frame.
- Since bugging an HP part gives two unique 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 lets 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 deal enough damage.
