I think that Sting Chamleon is the hardest boss in the game. Except for the final boss.

Same with me, except if you go against Launch Octopus without any upgrades its extremely harder than if you do have even the leg parts.

Sting is one of the easiest. If you can get the boomerang you can get him in a cycle, you hit him he falls then jumps, hit fall jump hit fall jump, you can get him in a lock then dispose of him at your whim, easy. hardest for me was the final boss, other than that I bassically never got hit except occy man

I think that Boomer Kuwanger is the hardest because even if you keep on firing the missiles at him, he just keeps on coming and he can teleport. Also, his bommerang that he throws is quite annoying.

Hmm, another hard boss is armoured armadillo without the spark shot, he is pretty tough.

I found Spark Mandrill to be the hardest boss for me, if I didn't use the Shotgun Ice. His large size made him difficult to avoid and his punch was surprisingly fast.

I think that the hardest boss would be Sigma. i kno its because he was the last boss and he was made to be hard but it took me forever to beat him. but i gusse if i had to choose another one i would choose Launch Octopuse. But i still say that Sigma was the hardest.

I agree that Sigma's second form is the hardest but if you have all 4 sub-tanks and use the Rolling Sheild on him you should beat him.

I thinks it's Armored armadillo. His attacks aren't too hard to avoid, it's just trying to hit the guy that gives me trouble.

hitting it with the X Buster and not using Spark Mandrill's Weapon is the most difficult.

Well, yeah he absorbs the attacks and sends them back at you. Anyway Storm Eagle on certain occasions is the hardest for me because of the fact that I can't see where he's flying around half the time.

I think that spider thingy in the first Sigma stage is the hardest because he's very hard to hit...

mmm.. DQ, I never knew you played this, I think that Sigma's Pet is hardest

I'd have to say the Launch Octopus was hard.
