Barrier

Barrier is a commonly seen battle chip from the MegaMan Battle Network series and has easily appeared in each version.

They come mainly in three forms: Barrier, 100Barrier, and 200Barrier.

A Barrier negates the corresponding damage (A 100Barrier will negate 100 damage.)

The NaviCust has a 'FirstBarrier' which activates a Barrier in the start of a battle. (It is always a 10dmg deducing barrier, same as a "Barrier" chip)
