|Artwork of Cannopeller from Mega Man 4.|
When Cannopeller is spawned, it will ascend up 1 tile, then descend 3 tiles, then ascend 3 tiles, and then it will repeat ascending and descending 3 tiles from then on. While it is ascending and descending, it will fire cannonballs that travel in an arch. These cannonballs can not be deflected by Shine or Proto Man's shield.
Cannopeller itself has no collision detection with solid tiles, but its cannonball projectiles do, causing them to detonate on contact.
- "Cannopeller"'s name is a combination of the english words "Cannon" and "Propeller".
