So first, you go inside the Masks and Capes building, and you talk to the man inside there, and he will give you an ID Card. Now pick out a suit! There are plenty to choose from, and you can mix and match as well. For example, I used the blue and orange suit's shirt, the red and yellow suit's pants, the pink and yellow suit's cape, the purple and yellow suit's belt, and the green suit's mask.
But then I relized I didn't like that and went with the blue and orange, but with the purple's mask. Anyway, go left to the island with the prison and talk to them all. Most will give you things. In total, you'll get the prisoners profile reports and some anti-powered handcuffs. Now go right, to the bank. Talk to the distressed banker. He will tell you that the villan, Copy Cat, is inside. To catch her, you will need to catch all of her copies. Once there is only one, you will capture her, too, with the handcuffs. You have to catch her before the place smokes up completely. If you fail, just try again.
You will be taken to the prison with her afterwards. Simply go right until you find the subway. Go down there and get on the train. Now we have to catch Speeding Spike. You have to lure him to the puddle in the first train car so that he slips and falls, and you can catch him. Simply do this by dodging his attacks. Each time you do, he will get madder and madder until his head gets red. Then he will run past you completely (If you dodge) to the next train car.
Again, you will be taken back to the jail. Just go right until you find a man selling hotdogs. Get one, because it will be needed later. Anyway, here you meet Sir Rebral. Dodge his attacks and make them hit him instead of you. When the ground starts coming up, find a rock and push it on the loose ground. Keep doing that until it hits him.
After the jail, simply go back to where you met Sir Rebral, but now go to the bathrooms. Go down the hole.
(Second one above was taken by ShirtDogNintendo) Now go left until you get to a
and you click it. Then go right until you find another one, and click that one, too. Find another in the middle, and click on it. Immediately go left and wait for the water to raise you to the door. Enter. We now find Ratman. Go to the top right until you find another one of those, dodging rats along the way. Click it, and water will pour out on Ratman, causing his flies to leave him and attack you. Dodge their attacks and get to Ratman to handcuff him.
NOW go past all of that this time and go to the junk yard. So now we have Crusher. He will stomp and try to make you fall. You have to get up onto that crane thing and move the lever's position. A fridge will smash him, and now he will be throwing things at you. Dodge him again and get back up there. This time, when you pull the lever thang, he will be crushed by the hood of the car.
Now, go to the phone booth, which should be ringing. You have gained the power to fly! Go to the really tall building and get to the top of it. Now we have Betty Jetty. Dodge her attacks while closing in on her, until you are able to knock her out of the sky. The comic book store guy comes out of nowhere and bashes her. He ends up with all the credit.
Go talk to him. He's in his Comic Book shop. He says he'll trade the medallion for a hotdog. Good thing we have that!
