The first show from what I remember was in London and it followed three kids. They thought they had physic abilities and tested them on a school bus with flash cards. They each individually woke up on an island and walked along a beach and found a circle, when they rubbed it they got sucked in and met something that gave them super powers or something. I also remember there was a lady that drove a limo that would release a small fly type thing to kill her passengers in the back. I think it may have came on nickelodeon. Early 90's late 80's
The second show I feel was called Exo something. Basically some kids had exosuits one was purple. They were kind of open on the sides and were dome shaped, and walked in two legs.
Both of these shows were live action.
Any insight would be greatly appreciated.
