This is a bit tricky but eventually you'll do it.You must keep the red line within the green area unless you go out of control.Don not look at the nightmare or you will not win.Sometimes it changes direction and goes fast.
The strong lightfoot is a challenge, but there is an esay way to get past it. Take the back end of a pen and run it back and forth across the A button during the strength test. This will easily defeat him in 5 seconds.
Here is how to defeat Andross. When he is at the Korzoa part of him, dodge the beams he shoots from his mouth while shooting his eyes and the crystal thing on his head.
Then he'll turn around and try to defeat you from there. Shoot his hands until the other hand comes up. Then he'll shoot rocks and health at you. If you need to, grap the health. He'll then try to suck you up. Don't get suck up or you will have to fight him as the Krozoa part all over again.
Destroy his hands and he'll turn to the Krozoa head. This time is harder. Keep flying around his head and shoot the stuff at the same time.
This time he'll shoot missles at you. Do the same as last time. Destroy his hands and he'll try to suck you up. There is nothing you can do now. Just let him suck you up.
Just before you enter the mouth, Falco will come in and shoot him. He will say: "Different time, different planet and you still need Falco's help. Good to see you buddy.
" He will toss you bombs when Andross blows rocks and health at you (sometimes. Just before he sucks you up).
When he tries to suck you up, shoot the bombs Falco gives you into his mouth. Then, shoot his brain. Repeat until he is destroyed.
