Power Up Items

Many up grades or power ups exist in the MegaMan Battle Network series that are used to power up MegaMan.EXE.

HP Memory
HP Memory increases a netnavi's max HP (Hit Points). It appears in every game in the series and increases a navi's HP by 20. In each game there are 45 HP Memories (in total raise a navi's HP by 900) giving MegaMan a base maximum of 1000 HP.

Power Up
Power Up is used to increase MegaMan's buster stats: Attack, Rapid, and Charge. Each Stat can be upgraded up to level 5 creating a total of 12 Power ups to be found in the game. Only available in MegaMan Battle Network and 2.

Sub Chip Memory
Introduced along side the concept of Sub Chips in MegaMan Battle Network 2, Sub Chip Memory increases the maximum number of Sub Chips one can carry. Appears from Battle Network 2 onwards.

Regular Upgrade Memory
Regular Upgrade (known as "Reg Up") increases the memory capacity for one's folder's regular chip. Each battle chip has a certain MB and if a folder has enough Regular Memory, this chip can be set to appear first in every battle. MegaMan Battle Network 2-6.

Expansion Memory
Expansion Memory is collected to increase the map space of the Navi Customizer. Only 2 exist in each game after MegaMan Battle Network 3
