Go fourarms, doge his attacks until his hand gets stuck in the ground then attack his belly. that should do the trick!
A2
: 
Turn into Heatblast now dodge his atacks like the blue lazer crouch down now when his red lazer goes up jump then when he smashes his hand in the ground jump and dodge the atack and the reason I told you to turn into Heatblast is because when he smashes his hand in the ground his hand gets stuck then with Heatblast you go right up to him and jump and press B and keep reapeting that. Hope that helped! :-)
A3
: 
Fourames, then jump twice when he uses his hand and press down when it is a blue beam, when it is a red beam go at the complete left and keep jumping, then you will have to destroy his hed go to the right and destroy the generator do the same with the left then attack his hed with X.
PS. I did this ALL in 1 night! -

(part 1) turn into any alien, first when the giant robot you fight shoots a giant beam at you,duck then it should shoot a shock wave you jump then its arm should be on the ground go toward the arm and climb up the arm and attack the chest keep doing this until the setting changes. to be continued
A5
: 
(part 2) go fourarms then in the second part of the fight go completely left and climb up the lader then you should see a generator destroy it then the screen should flash blue if it doesn't then destroy the right one when the big guy fall's attack his head keep repeating this accept destroy the other generator then congrats you have beat the level
A6
: 
Use heatblast. get in as close as you can, then as he starts to bring his hand up to knock you away press x 3 times. if he swats you and tries to use the blue beam duck. for the second part use XLR8 and break the generators on either side of the level, then hit him while he's down!
A7
: 
Go XLR8 and dodge his smacks and when he Slams himself against the dam jump and his other attack will be dodged then attack his belly its how I killed him
A8
: 
You have to turn into xlr8 , if he tries to chuck you away, keep on jumping and deafeting him , half way though his lives section. Until you will see a thing smoking wich is his genarator,when he shoots a red beam stay very close to its legs or if it is a blue beam duck wich is down on the control pad.That was just a hint,now for the easy bit.You will see that he's genarator is still smoking,now keep repeatng this turn into fourarms go right and left ,climb up the lader and whatever you see destroy it, destroy both then go to him keep on deafeating him.then after you get can get cannonbolt level 5,14 levels to go!

: 
Make sure you have the alien boost & defense boost upgrades for 4 arms . Duck the lasers and jump the arm crashes and keeping hitting the belly of big guy . Once he falls down - keep hitting him . If he gets up - run to 2 generators of either side and crash them - this will bring the big guy down again . Repeat this and voila - you r on your way !
