Canodumb

Canodumb (キャノーダム) is a virus in the MegaMan Battle Network series made up of a cannon on a base. These viruses cannot move, but they attack when MegaMan moves into the same column as them. The Cannon series of Battle Chips can be obtained from Canodumbs.

 * Canodumbs are green and have 50 HP in the first game and 60HP in later games. When a NetNavi stands in front of them, they send out a cursor. If the cursor comes in contact with a target, it will fire its cannon down the row of panels.

Trivia

 * Canodumb also had short appearances in the anime MegaMan NT Warrior. When the Cannon Battle Chip is used in the anime, it can be used either as a cannon in the NetNavi's arm or to summon a Canodumb.
