Powie

Powie, also known as Flappy, is a virus from the Mega Man Battle Network series. They hop around their area for a short while before jumping over to the player's side and becoming a weight that crushes down on the square which the player is standing on, cracking it in the process. They land faster as their version level increases.

Powie/Flappy
Powies are white and gray.

Powie2/Flappy2
 Powie2s are red, and their quakes leave an aftershock that can still damage its target if the target is within range (same column).

Powie3/Flappy3
 Powie3s are yellow, and their quake aftershocks are cross-shaped.

PowieEX/Flappy
 PowieEXs are light-blue, and their quakes leave an aftershock that can still damage its target if the target is within range (same column)

Powie2EX/Flappy
 Powie2EXs are purple, and their quakes leave an aftershock that can still damage its target if the target is within range (same column)

Powie3EX/Flappy
 Powie3EXs are dark-green, and their quake aftershocks are cross-shaped.

BigFlappy
BigFlappys are white and gray. This is normally the large version of regular Flappys when they are quaking their target. However, in Mega Man Network Transmission, this appears as a regular virus that continuously floats up to quake down. It paralyzes and damages MegaMan if he is still grounded.

Battle Chips
Powies leave Quake (アースクエイク, Earthquake in Japan) Battle Chips.
