This guy has your Power Bomb and spews it them out at you. There are those little Darkling guys, so shot them to gain more health if you need it. To beat him, there are 4 bomb slots near the top of the room. Use the Spider Ball to get to all of them. After you get to all the slots, a metal plate will crash on top of the gaurdian and crush him. THe power bombs will look all blue adn yellow and explode all over the place killing just about everything they hit. NOTE: After you defeat him, ther Power Bomb still requires ammunition. There also still those Power bombupgrade from the last game. Just so you know!
