Sakrets is an enemy that appeared in Mega Man 9.
It is a cannon-type enemy that has a cannon to fire on its top and wheels to move in a wall. It goes up and down in a wall and periodically fires a projectile that goes straight and goes still for a while before dividing in 8 directions. The Sakrets itself is susceptible to gravity.
The projectile can divide itself earlier if it is attacked. The minor parts cannot be destroyed.
