Act 1:
This is the boss for Launch Base. It would first appear from a box.
As you can see, this guy has two hands revoloving around itself. Don't go near it at this point. If he whacks you, you either lose rings or die if you don't have any.
Only when it stops, then you can whack it.
After a few whacks, the boss would lose a hand. A few more whacks and you win!
For Knuckles, you have two machines coming towards you! So watch out Knuckles players.
