Cannon (BattleChip)

The Cannon series are among the first chips, and stayed the whole series. They are in all of the standard folders. They do damage to the first target lined with the user. 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 Cannodumb virus being replaced with the Canoguard virus, a seemingly 'evolved' version of the Cannodumb.

Cannon
A standard battle chip. The starting folder in each game always contains a few of these.

HiCannon
A Cannon that causes more damage.

MegaCannon
MegaCannon, shortened M-Cannon, is the strongest standard chip in this family.

Dark Cannon
Dark Cannon is a Dark Chip, appearing in 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
ZetaCannon, shortened 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.

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

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