You Dodge the green orbs that she throws as you fly after her. If you get hit five times you fall. Try to avoid them for about one or two minutes and by then you can get close enough to her to knock her down.
Betty Jetty's not on TimeTangked Island she's on Super Power Island
The hero who defeats Betty Jetty will receive the Island Medallion! (hmm...see the related question)

At the end of Super Power Island, you go to the phone booth. (click on it) Then, you will get flight!!!!!!!!! You have to defeat Betty Jetty!!!!!!!!!
When you have captured the first 5 super villains (all but Betty Jetty), the pay phone on Main Street will ring. Answering gives you your super flying power, which is turned on and off by the icon at lower left. Now you can chase Betty Jetty at the top of the skyscraper.
On Super Power Island, Betty Jetty is atop of the skyscraper in the Downtown area. The building is cordoned off with yellow warning tape. To chase her, you will need to fly. Defeat the other five super-villains (without the flying power), and you will receive your flying power. (The phone in the phone booth will ring.) Go to the skyscraper and chase her when she flies away.
Open the booth when you have beat all the other villains besides Betty Jetty. Then you should get the power to fly and put Betty behind bars. :)
You only get one power : flying. Defeat the other 5 super-villains and you receive the flying power to catch Betty Jetty. (see related question)
