Cannon (Battle Chip)

 The Cannon series is among the first obtainable battle chips and stays throughout the whole series. They are in all of the standard folders. They do damage to the first target lined with the user. The battle chips can be obtained from Canodumbs or Canguards, depending on which game in the series is being played.

Cannon
A standard battle chip. The starting folder in each game always contains a few of these. Causes 40 damage in all games.

HiCannon
A blue Cannon that causes 80 damage. 60 in MMBN2-3.

MegaCannon
Shortened to M-Cannon, is the strongest standard chip in this family. Causes 120 damage. 80 In MMBN2-3. 180 In MMBN6.

DarkCannon
A Dark Chip appeared in MegaMan Battle Network 4. Its damage dealt is equal to the difference between your current and maximum HP, similar to an unrestricted ranged Muramasa. However, as with all Dark Chips, it has a glitch after being used, and this one drops all of MegaMan's Buster Stats to 1.

ZetaCannon
Shortened to Z-Cannon, is a Program Advance. It's created by combining three Cannon chips in code order (like A, B ,C). Z-Cannon1 is created with three Cannons, Z-Cannon2 with three HiCannons, and Z-Cannon3 with M-Cannons. The Z-Cannon in Mega Man Network Transmission is created by using Cannon, HiCannon, and M-Cannon.

OmegaCannon
O-Cannon is almost same as ZetaCannon, but is formed from the A B C D and E codes, and lasts longer.

Powered Cannon
This cannon is activated by combining Shotgun K + CrossGun K + Spreader K + Mega Cannon K and only appeared in MegaMan Battle Network. This creates a massive cannon firing in a spreader pattern.

GigaCannon
ZetaCannon changed to GigaCannon in MegaMan Battle Network 4, but it works differently. Instead of shooting multiple Cannons, it does a single hit of massive damage. In MegaMan Battle Network 6, it spreads to the 8 panels surrounding the point of impact as well.

Trivia

 * When the Cannon Battle Chip in used in the anime, it can be used either as a cannon in the NetNavi 's arm or summon a Canodumb.
 * Unlike most chips that come from Viruses that disappear in proceeding games (which become a 'black' version of the virus on the chip with damage usually in between the 3) all 3 cannons stayed in the entire series, despite the Canodumb virus being replaced with the Canguard virus, a seemingly 'evolved' version of the Canodumb, in MegaMan Battle Network 5.
