Yes, that is how I completed super power island!
get a power flower, and you can walk thru it.
probably to be super hot i do not know why though because he already is super hot
Just walk into the "Masks & Capes" shop, and walk out again. The man behind the counter will say "So you want to be a superhero, huh..." and give you it. Hope this helped.
You have to press the up button. You walk inside it and press the up button again.
Defeat the other 5 super villains (all but Betty Jetty). When you walk past the telephone booth, it will ring. Answer the phone and you will be given the power to fly. Now you can go after Betty Jetty, on the skyscraper Downtown.
You get it from Ned Noodlehead. He's in the comic shop. Click on him and talk to him. He gives it to you. You don't really need it, though. For a complete walkthrough of super power island, see my other answer.
The power to walk away
You don't discover your super power... You have to go to the island left after you get your super power card they give you your power handcuffs.
Once you have beaten them, just click on them and your character will walk up and cuff them. (For how to beat them, see the related question)
Hercules Super power is to be strong
No, there is no "super strength" on super power island glad to help :D
