Concrete Man

Concrete Man (コンクリートマン) is one of the Robot Masters from Mega Man 9 whose period of use had expired and was scheduled to be scrapped. Concrete Man is a construction robot built to be the supervisor of dam construction. He is stubborn and will tell off any lazy robots.

Boss Strategy
He tries to stop the player with his Concrete Shot, jumps from the top of the screen and shakes the floor, which will make Mega Man stumble, or tackles.

Concrete Man's weakness is the Laser Trident due to it's ability to penetrate most shielding. It can also cause critical damage to him, and can pierce through the blocks of the Concrete Shots.

Sub-Boss Strategy
There are three sub-bosses, which are metal elephants. They all have balls in front of them, then they'll roll or throw them toward Mega Man with thier trunks, then suck the ball back, then so on.

The first one is really simple. He has a pink ball and collar, so the ball will roll. There is a ladder right above the ground, and Mega Man can easily blast the elephant. The second one has a green ball and collar, so he will try to flip the ball upwards. Stay near the elephant then start firing. The last elephant also has pink gear, however, there is no ladder and there are holes in the ground. So if Mega Man gets hit with the ball when the elephant pulls it back, he will probably fall to his doom.
