To defeat the Alpha Blogg, you must first scan him if you want a good ending. However, this is optional. Once you are fighting him, make sure you always have him locked on. Sometimes he will shoot air bubbles at you, then charge at you. When he is charging, charge the Power Beam. Just before he hits you, fire the Super Missile. Do not do this too soon or late or you will hit his side. You will still get hit, but it will not do much damage if you have the energy tanks. Keep doing this until he is defeated. Additionally, the Alpha Blogg can be eliminated the same way you would take care of the normal Bloggs. The only differences are that you can move freely with the Gravity Boost and that the Alpha Blogg shoots sonic waves which will stun you and your gun for a few seconds. To kill it, charge your Power Beam and wait until it rams you. When it gets close to you, it will open its mouth. At that point, shoot like mad. The Super Missile will damage it the most. After you shoot, strafe and dash using Left or Right and B. Repeat this about four to five times to win.
After obtaining the Gravity Booster, you will have to face Alpha Blogg. While fighting this giant Boss, keep an extremely far distance from it. When attacking, Alpha Blogg can do one of two things. It can shoot blobs of goo which causes you to lose sight and lower your gun, or it can charge at you like regular Bloggs. If it starts shooting you, side-dash to dodge it. It will most likely charge at you afterwards. While charging, it will open its mouth just before it hits you. You can shoot a charged Power Beam shot or a Super Missile into its mouth. After shooting it, immediately side dash to dodge it because it does not stop charging after it gets hit. This Boss is not difficult if you keep a safe distance away from it.
